Reliable and durable chimney made of galvanized steel

A sturdy chimney is essential to keeping our houses toasty and comfortable throughout the colder months. An exceptionally strong and efficient chimney made of galvanized steel is a top option for homeowners. This resilient material has several advantages, including longevity and resistance to inclement weather. Let’s explore the benefits of installing a galvanized steel chimney for both heating and insulation in your house.

Durability is the most important factor to consider when choosing materials for important home elements like chimneys. Given its reputation for strength, galvanized steel is a great choice. Steel is coated with a layer of zinc to prevent rust and corrosion through the galvanization process. This coating guarantees that the chimney can endure the harsh conditions of continuous use and weather exposure in addition to extending its lifespan.

In addition to being long-lasting, a galvanized steel chimney has exceptional resistance to moisture and temperature changes. These chimneys are dependable for securely venting smoke and gases from the fireplace or heating system because they can withstand high heat without warping or weakening. Furthermore, because of their resistance to moisture, the chimney’s integrity is not compromised over time by the growth of mold, rust, or other damages.

Additionally, galvanized steel chimneys are relatively simple to install and maintain, which increases their appeal to homeowners. Steel chimneys are frequently prefabricated and assembled on-site, reducing installation time and costs when compared to traditional masonry chimneys, which need substantial construction and sporadic repairs. Their smooth surfaces also facilitate easier cleaning and maintenance, which adds to long-term time and cost savings.

Apart from its functional advantages, a chimney made of galvanized steel can improve the overall appearance of your house. Its sleek, contemporary appearance adds sophistication and blends in with a variety of architectural styles. A steel chimney offers design flexibility without sacrificing functionality, whether you’re building a new home or remodeling an old one.

In conclusion, it is a smart choice to purchase a galvanized steel chimney for the insulation and heating needs of your house. Its strength, ability to withstand harsh environments, simplicity of installation, and visual appeal set it apart from other chimney materials. Homeowners can benefit from the comfort and peace of mind that come with a well-built and effective chimney system by choosing quality and dependability.

What you need for the manufacture of galvanized pipes

You will need a sheet of tin plate at home to create a galvanized pipe; the material is soft and malleable, so it doesn’t require extra work.

Tin is produced industrially from thin sheets of steel that range in thickness from 0.1 to 0.7 mm using rolling machines. Following this, a protective layer of zinc, tin, or chrome is applied to prevent corrosion. The billets are then finally sliced to standard widths of 512 mm to 2000 mm.

These products are just as strong as their steel equivalents, even with the addition of stiffening ribs. However, they are much more flexible and can be used to manually install complexly shaped pipelines. The pipe is shielded from the outside environment by the anti-corrosion coating.

Due to the inadequate bending strength of these pipes, stiffening ribs are incorporated into the design during the manufacturing of non-closed parts in order to reinforce the final product.

  • In stores there is a wide range of such pipes of different sizes: single-circuit;
  • double-circuit (made in the form of a sandwich and consisting of an inner and an outer pipe);
  • corrugated, characterized by increased flexibility.

Kindly take note! It is technically feasible to create a single-circuit pipe at home. The pipe’s intended use should be considered when determining the sheet’s thickness.

For example, high anti-corrosion qualities and enhanced resistance to high temperatures are required for galvanized pipe used for smoke exhaust from solid fuel stoves and fireplaces.

The pipe’s intended use should be considered when determining the sheet’s thickness. For example, high anti-corrosion qualities and enhanced resistance to high temperatures are required for galvanized pipe used for smoke exhaust from solid fuel stoves and fireplaces.

It’s crucial! The thickness of the pipe walls should increase with the temperature of the working environment. Instruments


To bend, accurately measure the bend’s angle, and cut the pipe of the necessary section for the task, special tools are needed.

A collection of instruments required for the task:

  • metal shears;

Take note: The formation of an even edge on the product is dependent on the sharpness of the scissors’ blades. Sharp edges are created when cutting with a blunt instrument and need to be removed. It’s critical to keep an eye on the sharpening quality to prevent needless labor.

  • hammer with a rubber pad, mallet (a carpentry tool made of wood in the form of a hammer);
  • Bending pliers;
  • workbench for cutting and marking;
  • pipe for calibration of more than 100 mm and an angle with edges of 75 mm;
  • ruler or tape measure;
  • marker (sharpened steel rod).

Instructions for making a galvanized pipe

To create a strong seam in the future, the first step is to mark the iron sheet by drawing folds and bends on one side twice, each measuring five millimeters. The fold on one side should be wider than the second. Using pliers and a corner, bend the sheet 90 degrees on both sides.

It’s crucial! Gently bend the shape, going along the bend line from one edge to the other. Next, rotate the workpiece to create the folds and adjust the angle to between 135 and 140 degrees. Gently tap the tin’s edges with a mallet or hammer using a soft striker to avoid damaging the product’s material.

You can start creating the pipe itself after creating the folds.

After that, rotate the workpiece to create folds and adjust the angle to between 135 and 140 degrees. Gently tap the tin’s edges with a mallet or hammer using a soft striker to avoid breaking the product’s material. You can start creating the pipe itself after creating the folds.

Place the billet on the calibration template and tap it again until the folds are not connected to give it the desired shape.

Once more, the wide edge is bent at a 90-degree angle parallel to the product’s plane.

Using a mallet to create a flat seam to join the ends together is the final step.

After aligning the rebates, bend this seam and press it firmly against the pipe plane. Next, bend the second rebate’s horizontal portion and wrap it around the first rebate.

With the use of a welding machine, it is possible to further reinforce the location of the rivet connection using metal, though galvanized pipes joined by a flat seam typically do not require this extra support.

Preparation for the assembly of the galvanized chimney flue system

Anyone, even someone with minimal training, can install galvanized chimneys because they are so simple to put together. To ensure the best possible assembly organization, the following preparatory work needs to be done:

  • Select pipes of suitable diameter (from 100 to 1000 mm) and segment lengths (from 250 to 1000 mm), taking into account the conditions:
  • power of heating equipment;
  • How many devices will be connected to the structure (preferably 1);
  • what kind of fuel will be used for heating.

Stainless steel pipe is the queen of the market

Raw materials for stainless steel are highly sought after. It has well-known benefits as well as depressing drawbacks.

The true stars of the market, pipes, proudly display the following advantages:

  • durability;
  • environmental friendliness;
  • safety;
  • attractiveness;
  • availability;
  • practicality;
  • reliability;
  • lightness;
  • flexibility;
  • ductility;
  • rigidity;
  • resistance to the destructive action of mechanical factors;
  • resistance to the harmful effects of biological factors;
  • resistance to the destructive effect of chemical factors;
  • fearlessness to the negative influence of climatic factors;
  • resistance to the negative impact of thermal factors;
  • ease of installation
  • easy maintenance.

Furthermore, installing stainless steel pipe in a finished home is a simple task. It is also very convenient that it can be brought out at any angle. Stainless steel chimneys also clean themselves.

Regarding the drawbacks, they are as follows:

  • high price;
  • the need for insulation to avoid condensate formation.

When weighed against other raw material types, the drawbacks are minimal.

Stainless steel pipe blends in beautifully with:

  • solid fuel boilers;
  • liquid-fuel boilers;
  • gas-fuel boilers.

So, my dear friends, a great way to make a chimney channel is with stainless steel pipe. By the way, when constructing a structure, remember to include a gate valve—which is likewise composed of stainless steel.

Is it possible to paint a chimney made of galvanized steel

Galvanized steel can be painted; in fact, painting it is required. Paint will be a good way to add extra protection since rust does eventually start to seep through the zinc layer.

But the adhesion of the galvanized surface is not the same as that of, say, black steel. That’s why standard oil and alkyd paints won’t work here because they oxidize when they come into contact with zinc, losing their adherence and pealing off the painted surface.

Unique arrangements have been created:

  • Zicrol, a matte acrylic paint with high hiding power, lightfastness and adhesion;
  • Nerzhalux enamel, which is characterized by high adhesion and wear resistance;
  • aluminum enamel Silver, which reliably protects against rust and is adapted to outdoor use;
  • a number of other compositions that can provide long-term protection from rain, sunlight, temperature fluctuations, and do not harm the human body.

Painting should ideally wait until a year has passed after the chimney duct installation. During this period, its surface will develop the required roughness, resulting in a stable adhesion for coloring agents.

Advantages of using galvanized pipes

The primary benefit is the existence of the previously mentioned protective layer. It was discovered that any metal exposed to condensate will eventually rust, which compromises the tightness of the chimney channel and the effectiveness of its operation. However, the product will last a lot longer if it is well-protected from moisture. As a result, galvanized chimneys have grown in popularity recently.

Kindly take note! Good quality sheet steel is employed in production. Prior to molding, it is submerged in a zinc solution, where a chemical reaction occurs with the help of reagents.

This creates a protective layer that is more than enough to prolong the operational life.

Additionally, chimneys composed of this material offer the following benefits.

  1. High speed of heating and, as a result, almost instantaneous formation of a draught. This allows heating appliances to work as efficiently as possible.
  2. Such chimneys include several modules, which, if necessary, are quite easy to assemble.
  3. Installation of products can be made on any heating devices. Simply put, another of their advantages can be considered versatility.
  4. All galvanized pipes are resistant to fire, and therefore fire safe. And this is especially important for wooden houses.
  5. The installation requires a minimal amount of free space.
  6. Large variety of variations.
  7. High resistance to condensation (especially against the background of brick analogs). Only chimneys made of "stainless steel" are more efficient in this respect.
  8. Finally, the smooth surface prevents soot from collecting on the walls, making cleaning faster and easier.

Kindly take note! Considering everything mentioned above, we can say that stainless steel pipes are the only item of lower quality than galvanized products, which are far superior to brick. As a result, savings are thought to be their primary benefit (both on the purchase and installation work).

But keep in mind that cutting corners on the quality of the material you buy can frequently result in high maintenance and repair costs.

Features and advantages of galvanized pipes

Moisture by itself is harmful to most iron-based alloys because it oxidizes the metal and causes rust. The products of fuel combustion, which include a variety of chemically active substances that, when combined with water, exacerbate the damage to the inner surface of the chimney flue, travel through the flue channel with the constantly moving condensate.

Iron pipes are coated with zinc to shield the metal from the corrosive effects of water. To achieve this, premium sheet steel is submerged in a zinc solution, causing a chemical reaction that results in the formation of an extra layer of protection on the metal’s surface. The sheets are then cut and stitched into pipes.

Pipes made of zinc are widely used:

  • Due to the lightness of the material.
  • The cost of pipes is significantly lower than that of ceramic and copper products.
  • Smooth inner walls prevent the settling of combustion products and condensate accumulation.
  • Durable metal, protected by a layer of zinc, withstands temperature, chemical and mechanical stresses.
  • The metal walls of galvanized pipes heat up quickly, speeding up the appearance of the draught.
  • Convenient shape of pipes allows you to install chimneys of different configurations with your own hands.
  • The material is suitable for the arrangement of a combined chimney outlet.

Note: Heating appliances that operate at temperatures higher than 350 degrees Celsius cannot be connected to chimneys using galvanized pipes. Strong heating causes the protective coating, zinc, and other materials to oxidize when there is moisture present in the pipe. release harmful vapors that are harmful to health

Manufacturing of galvanized pipes with your own hands

Three steps are involved in the production of galvanized steel cylinders and covers:

  1. Preparatory. It starts with marking and ends with cutting out the finished "pattern".
  2. Molding. At this time, a given profile of a chimney or ventilation box is formed.
  3. Final. At this stage, the opposite edges of the workpiece are joined together.

We will now go into great detail about the manual process of making galvanized pipe.

Cutting out the blank

Cutting tin with scissors is simple.

Draw a sketch of the product on a sheet of galvanized tinplate. Follow these steps:

  • Cut out the resulting measured piece of sheet metal on which you have drawn the outline of the product you require.
  • Roll out the galvanized sheet on a flat area of the workbench. Measure the length of the box from the top edge and make a mark there.
  • Take an angle and from the mark of the product length draw a line perpendicular to the side edge of the plate.
  • Mark on the upper edge of the workpiece and the marked line of the length of the product the size of the perimeter of the ventilation box or the circumference of the chimney cylinder.

Note: To form joint edges, the circumference or perimeter should actually be increased by 15 mm.

  • Connect the obtained marks at the top and bottom.
  • Cut out the "pattern" from the sheet by making a side and longitudinal cut.

Note: You can use a tape measure or the school geometric formula to determine the circumference of the galvanized chimney pipe based on its diameter. Add the dimensions of each side of the box to find its perimeter.

Shaping the profile

Using pliers to bend the sheet is preferable.

Now move on to creating the future structure’s profile.

  • Mark along the billet bend line rebate (on one side 0.5 cm, on the other – two times 0.5 cm).
  • Bend the folds at an angle of 90˚ to the plane of the workpiece, which was previously placed along the steel angle (its edge should coincide with the line of the fold bend).
  • Deform the sheet with hammer blows until it makes contact with the second plane of the corner.

Crucial! The sheet should be gradually reshaped by moving slowly along the fold line. Use pliers to assist with the task at first.

  • Make an L-shaped bend on the 1 cm rebate along a 0.5 cm line parallel to the plane of the workpiece.
  • Now start molding the body of the chimney. Place the workpiece on a calibrating plane and tap the galvanizing with a hammer until you have a profile of the desired shape. The rebates at the end must meet.

Machining of the butt joint

Align the vertical rebates together to crimp the butt joint. In order for the horizontal portion of the L-shaped rebate to encircle the vertical rebate of the opposite edge of the structure, fold it down. Press the extending "sandwich" up against the chimney plane by bending it.

The problem of how to construct a chimney out of galvanized steel has been resolved. We hope you have success!

Material characteristics

Under factory conditions, thin sheet steel coated with zinc must adhere to GOST 14918-80.

The primary attributes to consider when making a decision are:. Sheet épaisseur

The most typical thicknesses for galvanizing are between 0.35 and 3 mm.

Processing a sheet becomes simpler the thinner it is, which is crucial for home product manufacturing. Remember, though, that less thickness equals less strength.

  • Thickness of zinc coating

Based on the thickness of the zinc coating layer, three classes of materials exist. For ease of use, let’s summarize the information in the table.

Class of steel by thickness of the zinc layer Weight of the protective layer present on both sides (g) Thickness of coating (µm)
P (Elevated) 570 – 855 40-60
I 258-570 18-40
II 142.5-258 10-18

GOST permits certain thickness variations and the existence of certain flaws.

  • NR is normal thickness variation;
  • SD – reduced thickness variation.

Variations in the sheet’s appearance:

  • CR – With crystallization patterns (some cracks and darkening);
  • MT – without patterns.

An essential feature in the production of pipes is the metal sheet’s capacity to draw:

  • H – normal drafting;
  • D – deep extraction;
  • VG – very deep extraction.

The ductility of steels marked VG is the highest, while that of steels marked H is the lowest.

Species diversity of steel pipelines

  • Single-circuit type. The system consists of the galvanized steel pipe itself and various connecting parts (fittings). These include tees, bends, gates, revisions.
  • Two-circuit insulated chimney pipe, because of its design, which received the name "sandwich", is available in two versions:
  • It consists of three parts: the inner pipe, made of stainless, acid-resistant steel; the outer casing of galvanized iron; insulation – basalt wool. High-quality, with a long shelf life and much cheaper construction than completely made of stainless steel.
  • It consists of three parts. First – the inner pipe, which will be subjected to a large thermal load, is made of galvanized steel with a thickness of 0.6 – 1 mm (not less). The other is an external, also galvanized pipe, with a wall thickness of 0.5 mm. To give a better aesthetic appearance, the outer pipe is covered with special heat-resistant means: enamels, powder spraying. It is also possible to polish the product.

Installing two-circuit chimneys is preferable since they contribute to the heating appliances’ increased efficiency. Nonetheless, in order to give their visible portion an appealing appearance, work must be done on its design. For instance, constructing a chimney box out of polymer-coated corrugated sheet or covering it in brick.

Advantages of using galvanized pipes

The primary issue with galvanized flue ducts is the damaging effects of condensate buildup on the chimney’s inner surface. The manufacturers apply a unique anti-corrosion composition to the structure of these chimneys in order to prolong their service life. Such a protective layer typically has an average thickness of 60 microns.

The following are the key benefits of installing galvanized chimneys:

  • high fire resistance;
  • increased resistance to fire;
  • quick and easy installation;
  • versatility of application;
  • wide range of constructions;
  • ensuring good draught;
  • high thermal efficiency;
  • smooth inner surface, not capable of accumulating soot and grime.

At the customer’s request, additional thermal insulation is installed, which improves performance parameters.

It is advisable to use special pipes with the presence of an additional thermal insulation layer when installing a galvanized steel chimney system in areas with harsh climates.

How to make a pipe with your own hands.

For self-manufacturing of a pipe with a round cross-section, you will need thin sheet steel black or galvanized, 0.45 – 0.5 – 0.55 mm thick. This thickness of material is sufficient for the device of low-pressure or household ventilation, exhaust from gas equipment, drainage system. On the sheet of metal, use a sharp metal scribe and a long ruler to draw the outline of the future pipe. Measure the length of the blank equal to the length of the pipe. If the pipe will be inserted into the next pipe, add the length of the "bolt" (e.g. 7 cm) to the length of the blank. Calculate the width of the pattern by multiplying 3.14 by the inner diameter of the pipe in millimeters: D*3.14 (mm). Add rebate allowance to the resulting size – 14 mm on both sides, or 28 mm to the width of the pattern on either side of the pipe. Final formula for the width of the blank: 3.14D+28 (mm). Cut the delineated blank out of the sheet with hand-held metal shears.

Draw and bend two edges in different directions along the length of the blank for the pipe rebate connection. The bent edges measure 7 mm in width. These edges can be bent obliquely, for instance, 7 mm for one end and 9 mm (or 6 by 8 mm) for the other end of the future pipe. After that, inserting the pipes into one another is simple and secure. The following figure illustrates the rebate joint preparation sequence:

A thick-walled metal pipe with a diameter of 80 to 100 mm, suspended horizontally from a board or a flat wall in two "clamps" made from strips of thin sheet steel, is required to give a straight sheet of tin plate the shape of a pipe, as illustrated in the accompanying figure. Place the pipe pattern with the ready-made rebates in the space between the board and the hanging pipe. Then, progressively bend it to take the desired shape around the reference pipe, pressing the blank down with each bend:

Take the workpiece out of the fixture, check how correctly and evenly it is "rolled" into the shape of the pipe. Lock the folds. Make sure that both fold edges are securely seated into each other along the entire length of the joint. Place the rebated workpiece (or part of it) on the rail section extended outside the workbench. Seal the folded seam of the pipe with a wooden mallet. Along the entire seam to precipitate the material, that is, undercut with the edge of a hammer or mallet, thus creating an additional lock, which will not allow the folded edges to extend out of the connection. The assembly can be secured with rivets.

Straighten irregularities and possible ribbing of the homemade pipe on the rail with a wooden hammer or mallet. Select the sheet steel for the manufacture of pipe products such that the surface of which does not remain at all, or leaves little noticeable trace when it is bent and unbent. This property of metal can be checked by slightly bending and immediately unbending the tin plate in the corner of the sheet. If roll material or galvanized sheet, obviously cut from the roll, is used for pipe manufacturing, it should be cut in such a way that the direction of bending, rolling of the billet coincides with the direction of the rolled roll – this will reduce the appearance of ribs along the deflection lines. The optimum length of the pipe is 1 m or 1.25 meters, which coincides with the transverse dimensions of standard tin sheets.

The page "Manufacturing of ducts" provides a brief description of the different methods used in the mechanized manufacture of pipes from thin sheet steel using machines.

Types of galvanized steel chimneys

There are two varieties of galvanized chimneys available: insulated single-circuit and double-circuit chimneys.

Stainless steel and galvanized steel fittings

Single-circuit chimneys

Such a chimney’s design is made up of pipes and shaped components, including revisions, bends, tees, and vents.

The stove operates more efficiently when the brick chimney is lined with galvanized pipe.

Mostly single-circuit chimneys are used to lay the flue duct inside the room or placed inside a brick chimney. The disadvantages of single-circuit galvanized chimneys include the formation of a large amount of condensate, especially if they are connected to modern heating appliances with high efficiency and low temperature of exhaust gases. To avoid this, it is necessary to insulate chimneys, which will reduce the heating time of the chimney, accelerate the formation of the necessary draft, reduce the formation of condensation and prevent heat loss. Single-circuit galvanized chimney pipes are often used for quick and quality repair of brick chimney flues (see "Single-Circuit Galvanized Chimney Pipes"). Chimney repair). Instead of repairing deteriorating masonry, a prefabricated modular structure made of galvanized pipes of suitable diameter is installed inside the brick chimney after cleaning and removal of collapsed elements. A layer of non-combustible mineral insulation is laid between the pipe and the brick walls to increase the efficiency of the new chimney. It is not recommended to use galvanized pipes as an external chimney. If necessary, they should be insulated from the outside.

Double-circuit chimneys

The name "sandwich" refers to the design of these chimneys. Although galvanizing is a less expensive material, stainless steel is typically utilized to make them.

Sandwich chimney made of stainless steel with a galvanized steel exterior

The following sandwich variations made with galvanized steel exist:

  1. The inner tube of the sandwich chimney is made of high-quality stainless steel, and the casing is made of galvanized steel.
  2. Both inner and outer pipe – galvanized steel.

Corrugated sheet chimney boxes coated with a polymer

Take note! The primary thermal load-bearing internal galvanized chimney pipes should be constructed of steel with a minimum thickness of 0.6 mm, ideally 1 mm. A half-millimeter wall thickness is adequate for an external chimney.

To give the structure a more attractive appearance, the exterior of the chimney can be painted in a decorative pattern or coated with heat-resistant enamel or polymer-powder spraying. Installing an insulated two-circuit chimney is preferable to installing a chimney from a single pipe because it improves the efficiency and functionality of heating appliances. But sometimes, a galvanized chimney detracts from the building’s overall aesthetic. One of their few drawbacks is that it can be concealed by building a box out of appropriate material or just covering the visible portion of the chimney on the roof with bricks.

But sometimes, a galvanized chimney detracts from the building’s overall aesthetic. One of their few drawbacks is that it can be concealed by building a box out of appropriate material or just covering the visible portion of the chimney on the roof with bricks.

Advantages of steel construction

The galvanized element’s ability to produce smoke with a layer of protection on the metal walls is one of its primary benefits. As you are aware, any metal exposed to the acid in the condensate will eventually corrode and actively rust. As a result, the chimney structure depressurizes and the stove’s or fireplace’s efficiency is significantly decreased. On the other hand, long-lasting and flawless material performance is guaranteed by effective moisture protection of the metal. The zinc layer that covers the steel base provides this defense. Acids cannot rust metal because zinc does not react with them.

Galvanized metal sheets are the best and strongest available. The process of manufacturing involves lowering the steel billet into a container containing liquid zinc. This initiates a series of chemical reactions that result in a dense bond between iron and zinc molecules. This substance is entirely new; it is not merely an alloy. Only a few tens of micrometers make up the tiny thickness of the zinc layer on the steel base. Whether the products are buckets or stove and fireplace chimney elements, the thin layer successfully shields the steel from all chemical influences and greatly extends their service life.

Chimneys composed of a thin layer of zinc-coated steel have a number of advantages over all other comparable materials.

  • The construction is not monolithic, and the assembly of several steel parts into a single unit is a very simple process, which is quite feasible with your own hands.
  • Any product made of galvanized iron is absolutely unaffected by fire and does not pose any fire hazard, which is extremely important when constructing stove equipment in buildings made of wood and other flammable materials.
  • Versatility – steel elements can be fitted into any type of fireplace, stove or boiler appliance.
  • Rapid heating of such structures provides literally instantaneous draft force, thanks to which the efficiency of stoves and fireplaces of any design increases significantly.


The variety of galvanized steel chimneys available in today’s building material market is simply astounding. Certain replicas even incorporate an insulating layer into their design, which enhances the functionality of items constructed from this material and raises the stove heating system’s efficiency. Selecting the best single, double, or even triple-wall chimney for a given design is very simple and will be the best complement to the intended stove, fireplace, or solid fuel boiler.

Usually pipes with one wall are used when this heating element is installed not by itself, but inside the brick construction. The device of such a chimney includes several parts, which, in turn, consist of different elements: bends, revisions, tees and some others. All these details are very important in maximizing the efficiency of the removal of combustion products. The bare pipe must not be used outside the room. Basically, the undesirability of such an application is explained by the formation of a large amount of water condensing from the air, which at negative temperatures will freeze and adversely affect the efficiency of work. So for the exterior of the pipe it is better to use double-walled structures with insulation or an air layer. In such constructions there are two layers of metal, an inner and an outer wall with insulation material in the middle. Condensate on such an element practically does not form, and the appearance of a double-walled construction is much more aesthetic and optimally fits into any modern design of the exterior of the house.

It is important to note that there are two varieties of pipes with two walls. One of them has two walls made of galvanized metal, while the other has an inner wall made of regular stainless steel and only the outer surface galvanized.

Application of zinc

The only way to galvanize is on a production line. In order to accomplish this, the steel billet is submerged in a unique mixture that permits the metal to amalgamate with zinc ions. When viewed in good light, the resulting layer of protection resembles crystalline divots. This gives galvanized chimneys a rather unique appearance.

Since the zinc layer is so thin, it naturally starts to lose its protective and aesthetic qualities over time. However, the zinc coating itself offers superior damage resistance to the chimney pipe and significantly prolongs the system’s lifespan.

When compared to other types of constructions, galvanized pipe chimneys offer a clear advantage. For instance, there are two major issues when combustion products are released through a brick chimney: first, there is a lot of soot, which requires frequent cleaning of the chimney; second, the structure is large and heavily weighted. These drawbacks do not apply to chimney galvanized pipe since gas layers form on the inner surface of the pipe very slowly as it passes through the channel.

For any chimney, soot buildup is a major issue, particularly when there is cooling vapor present that condenses. Moisture trickling down the building’s walls causes tiny irregularities on the chimney’s surface, which increases the likelihood of buildup and reduces draught. The release of gas into the atmosphere via galvanized pipes will eventually cease, which may have unfavorable effects.

You can remove the problem’s effects but not its causes by cleaning the chimney on a regular basis. The truth is that condensation will always happen, and the chimney’s condition will deteriorate over time. A galvanized stove pipe with a unique valve that lets you remove extra moisture from the channel is a good solution. Furthermore, you can employ passive methods to prevent corrosion in the structure, such as insulating the chimney all the way around and using materials that won’t rust.

Chimney insulation

A single-wall pipe’s galvanized chimney is vulnerable to a lot of condensation because of the temperature differential between the smoke and the surrounding air. Furthermore, condensate has a detrimental effect on the heater if the chimney itself experiences little moisture buildup. Drops that form on the pipe’s exterior cause the draft to deteriorate and have a destructive effect on the roof. Chimney insulation aids in the solution of this issue.

Thermal insulation is achieved by using fireproof insulation materials.

  • Basalt mineral wool, produced in the form of elastic fiber plates or ready-made dense cylinders;
  • backfill: broken bricks, slag, expanded clay.

The pipe is wrapped in rolled mineral wool, and a brick shaft is built around the finished structure. If you use cylindrical basalt insulation, place the cylinder on the pipe first, and then either build a shaft around it or cover it with a steel casing. When employing backfill materials, the flue duct is put together, a shaft is constructed around it, and insulation is then poured into the shaft.

If the combined chimney’s exterior is made of metal, it can be painted; if the shaft is made of brick, it can be plastered.

Calculation of the diameter of the chimney pipe

If the height is selected individually under the general characteristics of the house, taking into account the parameters of the attic room and the angle of the slopes, then the diameter of the pipe will depend on the heating unit. From the productivity of boilers and stoves depend on the volume of released fumes – respectively, under the power potential is selected and the design of the outlet channel. So, for units with power up to 3500 W it is desirable to install structures with a thickness of 80-100 mm. The size increases as you get closer to 5200 watts. For such boilers are recommended standard galvanized pipes for 120 mm. Chimneys with a large diameter must also be calculated taking into account the presence of auxiliary layers – both insulation and reinforcement.

Two-circuit configurations and thick walls are characteristics of structures that have a thickness of 120 to 150 mm. In other words, there is an additional technological layer of insulation that has no effect whatsoever on flow capacity. For instance, the insulation may take up to 15-20 mm in a galvanized one at 150 mm. It is worthwhile to discuss thermal insulation materials separately, though.

Completion of galvanized flue pipe

A lot of docking swivel components are included with galvanized chimneys, which makes installation much easier, especially when going through floor slabs and roofs:

  • pipe – on sale is available in a variety of diameters, which allows you to connect to a variety of heating appliances;
  • tees – used for connection to the heating system and installation of branching;
  • elbows – facilitate the installation of bends, as they come in different degrees;
  • additional elements – for easy passage of the chimney through the roof;
  • revision tees with a door for cleaning the construction from impurities;
  • Condensate collectors – elements for eliminating condensation;
  • mouth – the last element, one side of which has a layer of insulator;
  • clamp – is used when fixing the chimney to the wall;
  • support console – a base, which can be either floor or wall-mounted.

How to make a perfect galvanized pipe with your own hands step-by-step instructions

Greetings, valued visitor!

In 1867, the first galvanized sheet was removed from a British factory’s conveyor belt. But all that was covering the metal at the time was silver and gold. However, parts with a zinc protective layer were first manufactured prior to World War I, and ever since then, their popularity has skyrocketed.

This is to be expected since zinc multiplies the half-life of iron by 20–30. Items composed of galvanized steel are far more resilient, rust-proof, and behave no worse in daily use than stainless steel—all at a significantly lower cost.

In this post, I’d like to draw your attention to this underappreciated material more and show you how to DIY a galvanized pipe.

Advantages and disadvantages of such a chimney

Steel, which has numerous unquestionable benefits, is the main material used in galvanizing.

Among them are:

  • Durability,
  • Ability to withstand high temperatures,
  • Excellent thermal conductivity,
  • Low cost compared to other materials.

However, black metal is prone to corrosion, rusts easily, and becomes damaged if it isn’t coated. This issue has been effectively resolved by galvanizing. Furthermore, galvanized products have several benefits over steel pipes, even though their shapes are the same.

Extra benefits of galvanized products:

  1. Corrosion resistance, ability to resist negative environmental influences,
  2. Longer service life,
  3. Increased durability,
  4. Wide range of working temperatures,
  5. High resistance to mechanical influences,
  6. Galvanized pipe can withstand high internal and external pressure,
  7. Simplicity and ease of installation,
  8. High resistance to fire,
  9. Zinc kills all pathogenic microorganisms,
  10. Galvanized iron is practically as good as low-alloyed stainless steel, but it costs an order of magnitude cheaper.

Nevertheless, the pipeline made of galvanized iron is not perfect, just like any engineering solution.

  • Not very attractive design,
  • Expensive compared to conventional steel,
  • Zinc makes welding more difficult,
  • Unlike plastic, in the presence of protrusions on the walls, to provide a smooth transition in the design of galvanized pipes, almost impossible.

Do it yourself or order it

Which is better, going to the store to purchase a ready-made item or purchasing a galvanized sheet of the necessary thickness and bending the pipe yourself?

Selection tips

As is customary, let’s begin with the cost. For you and me, a pre-made pipe measuring 100 mm in diameter and 3 meters in length will set us back about 500 rubles. In this instance, the cost of the material was 150 rubles; the remaining amount came from labor and the seller’s markup.

And if setting up an entire gutter system is the plan? As you can see, paying too much for pre-made items will have to be done three or four times. The financial load will be greatly reduced if pipes are produced on-site.

Furthermore, factory products are defined by strict dimensions, and it can be challenging to find the exact one that fits your system. Yes, and the finished pipe’s thickness typically doesn’t go above 1 mm.

Keep in mind that, in contrast to homemade products, factory-made goods are strictly regulated by OTK and feature flawlessly rounded surfaces and precise welds.

It is far from certain whether the home master will be able to guarantee adherence to all of these requirements.

What material to choose

If the decision was made to manufacture the part independently, the first thing you should do is choose the material—in this case, galvanized sheet—and the necessary thickness.

Material characteristics

Under factory conditions, thin sheet steel coated with zinc must adhere to GOST 14918-80.

The primary attributes to consider when making a decision are:. The most typical galvanizing thicknesses range from 0.35 to 3 mm.

Processing a sheet becomes simpler the thinner it is, which is crucial for home product manufacturing. Remember, though, that less thickness equals less strength.

  • Thickness of zinc coating

Based on the thickness of the zinc application layer, three classes of materials exist. For ease, let us compile the data into a table.

How to create an ideal galvanized pipe by hand: a comprehensive guide Benefits and drawbacks of galvanized pipe, properties of the substance. detailed instructions, including dimension calculations, drawings, and schemes, to assist you in making a galvanized pipe by hand.

Work process

Let’s get our hands dirty and start creating a tinplate pipe.

The entire procedure can be roughly split into multiple primary steps:

  1. Preparation. This includes marking out the product and cutting out individual blanks from a piece of tin plate.
  2. Forming. At this stage, the initial formation of a round cross-section pipe takes place.
  3. Connection. Here it is necessary to finally sew the parts into the finished product.

Let’s take a closer look at each of them.

Step 1. Preparation

Mark and cut a blank from a large piece of tinplate to the required size before beginning to make a tin tube. (See also the article Features of exhaust pipes.)

You won’t need any complicated instructions because everything is this easy:

  • The sheet is placed on a level area (workbench or floor);
  • from the upper edge is measured a section equal to the length of the future pipe (marks can be put marker or a special marker);
  • then a line perpendicular to the upper edge of the sheet is drawn through the mark using an angle bar;
  • On the upper edge and the line drawn below, the width of the blank is measured, which is equal to the length of the circumference of the pipe (and to this parameter it is necessary to add 15 mm for the arrangement of the joint);
  • all the marks are connected, after which the blank is cut along the resulting lines.

Advice: Using the well-known formula L = π D, where π – 3.14 and D – the diameter of the future part, you can quickly determine the length of the circle (the width of the blank) if you know the diameter of the pipe.

Proceed with caution when marking the workpiece.

Step 2. Forming

Forming the future pipe’s round profile is required after obtaining the blank.

This work is completed as follows:

  1. A line for folds is marked out. Its width is 0.5 cm on one side and 1 cm on the other. The folds are bent at an angle of 90 degrees to the plane of the sheet of tin plate. A steel angle and a mallet can be used for this purpose.

Method of bending a tin sheet to form a pipe

After positioning the tin plate sheet on the table’s edge and offsetting it to the required length, the edge is gently bent with a rubber mallet blow. It should be firmly in contact with the angle’s bottom plane at the conclusion of the work.

Throughout the whole length of the workpiece, the work must be completed uniformly. You can use pliers to make the procedure easier.

  1. Then on the centimeter fold another bend in the shape of the letter G is made. The upper part (its width should be 0.5 cm) should be made parallel to the sheet of tin plate. It is desirable to make markings in advance for this bend as well.

Using pliers to bend a sheet of tin

  1. After finishing the work with the folds, we move on to work on the pipe itself. For this purpose, you can use a pre-prepared round piece. Having placed the sheet of tin sheet on it, it is necessary to give it a rounded shape with the help of a mallet. This should be done gradually along the entire length of the sheet until the bent edges meet.

Step 3. Grime

All that’s left to do is join the edges and secure the seam. This is accomplished by bending the larger rebate’s horizontal section downward to cover the opposing edge. Next, using a mallet, bend the projecting seam to the pipe’s plane.

In order to prevent water from getting under the seam and into the inner space of the pipe, the bend must be made in the opposite direction from the L-shaped rebate.

Plan for joint rebate

Asbestos product go away, old lady, I"m in sorrow

For a very long time, asbestos pipes shone in the brilliant light of glory; however, or fortunately, their heyday was short lived as new and creative raw materials came into existence. Naturally, one benefit of them is their affordable price. That’s the only thing. However, there are numerous drawbacks. They are listed in the following order:

  • short service life;
  • formation of condensation that destroys the walls of the product;
  • susceptibility to cracking;
  • The formation of suction, which contributes to a significant deterioration of the draught and penetration of combustion products into the room;
  • content in the composition of environmentally hazardous substances;
  • The accumulation of extremely huge amounts of soot, as the walls are not characterized by smoothness;
  • susceptibility to fire, which is fraught with a powerful explosion.

Experts advise against purchasing raw asbestos materials for building a chimney. Please don’t, unless you are obviously sick of living. It should be noted that the purpose of this kind of pipe was never to create a conduit for the combustion products to exit the building. They were created to meet agricultural needs.

Variants of asbestos were used when private homes were being built in large quantities and the nation was experiencing widespread shortages. There were plenty of adversaries. So, what are your options? In Africa, a shortage is a shortage. Additionally, homes had to be built. But, my readers, there are many cutting-edge materials available now that are renowned for their strength, resistance to deterioration, beauty, and safety.

Application range for chimneys made of asbestos pipes: gas boilers, gas columns, etc. Using the pipes to build chimneys for solid fuel fireplaces, stoves, and boilers is strictly prohibited.

Friends, asbestos material is not worthy of your attention. Consequently, I implore you to decline to buy these goods.

Galvanized steel for chimneys

Steel sheets with a galvanized finish

How it is produced?

The main enemy of any metal product is corrosion. Iron is particularly susceptible to destruction from moisture and other aggressive environments, so people are constantly inventing ways to protect it. The invention of steel alloys solved this problem only partially, but it was still possible to defeat corrosion when a man came up with the idea of applying a thin layer of zinc to the surface of the metal. For this purpose, thin sheet steel or its products are immersed in molten zinc. As a result of a chemical reaction, zinc and iron molecules bond together and form a protective layer on the surface of the metal with a thickness up to 60 microns. Zinc coating extends the life of steel products for decades, protecting them from corrosion.

As a point of reference. In our nation, cold-rolled carbon steel is used to make galvanized steel, as per GOST 14918-80.

Advantages and disadvantages

If we contrast galvanized chimneys with brick and stainless steel chimneys, it will be simpler to weigh the benefits and drawbacks of each material.

  • Galvanized as well fire-resistant and fire-safe, as stainless steel.
  • Also rapid heating of the chimney, which is very important for creating a quality draft. Brick chimneys need more time for this purpose.
  • Galvanized chimneys universal, They can be installed on heaters operating on solid, liquid and gaseous fuels.
  • Convenience of installation and the minimum required installation area.
  • The same wide, as with stainless steel, the range of products, the possibility of manufacturing double-walled chimneys with thermal insulation.
  • Compared to brick chimneys, galvanized chimneys Better resistance to the aggressive effects of condensate, But if you compare them to stainless steel chimneys, they have lower resistance to corrosion from acids and condensation.
  • Smooth inner surface of galvanized chimneys does not allow soot to accumulate on their walls in large quantities.

In summary, a galvanized chimney is preferable to a brick chimney, particularly if it is insulated, but it lacks the benefits of a stainless steel chimney. The chimney’s installation costs are lower, which is its sole benefit over stainless steel structures. It should be acknowledged, though, that cutting corners on material quality frequently results in a need for more frequent chimney repairs and quicker replacement.

Galvanized or stainless steel

The most popular products after galvanized products are stainless steel stove structural components. They can even be mistaken for one another if you are unfamiliar with the different kinds of metal. It can be challenging to determine which type of iron is superior, stainless or galvanized, if you do not understand the nuances of technology. The following technical characteristics of the two types of steel must be learned in order to compare and determine which option is the most effective:

  • In terms of fire safety, it is impossible to identify the leader. Steel, whatever it is, does not burn, so both zinc-coated and stainless steel are absolutely equally safe.
  • Heating of the material when the stove is fired up is equally fast when both materials are used in the chimney construction. Accordingly, and the thrust force in pipes made of metal with a layer of zinc and stainless steel, exactly the same.
  • Manufacturing of the construction from elements of both types of steel can be made on any type of heating equipment. The volume occupied is the same, the complexity and speed of installation do not differ – both galvanized and stainless steel parts are mounted simply and very quickly.
  • Galvanized pipes, unlike stainless steel products, can have insulation in their construction.
  • Stainless steel, however, beats galvanized steel in its ability to keep condensation from forming.

As a result, no discernible difference between the two analogs is noteworthy. Both financial constraints and aesthetic preferences may influence the decision. It will be feasible for them to put products together by hand in any situation.


The best option for installing a chimney for installed solid fuel or gas fireplaces, stoves, and boilers is to use galvanized sandwich pipes made of AISI 309 steel. This grade of steel has a composition that includes 20% nickel and 25% chromium, which increases the steel’s resistance to high temperatures and strength properties. Here is a summary of the various types of chimney flue screens:.

The image displays the AISI 309 heat-resistant stainless steel double-wall chimney’s component parts.

Because of the middle thermal insulation layer, two-circuit sandwich pipes are resistant to temperature variations between outside air and flue gases, and their service life is significantly longer (30 to 40 years) than that of single-circuit pipes.

The kit’s parts required for installing a galvanized steel chimney are displayed in the picture.

Because they can be purchased for relatively little money, galvanized steel chimneys are highly sought after by average-income consumers. Because of their heat-resistant enamel or powder coating, galvanized steel chimneys are visually appealing and don’t require extra decorative elements.

Necessary tools

The list of instruments and supplies required to create their own galvanized chimney pipe, given the softness and malleability of tin. Processing this kind of material doesn’t call for extra steps that are required when handling sheet materials.

Thus, in order to make tin pipes for the chimney, the following set of tools is required:

  • Scissors for cutting metal. This tool helps to cut the sheet material into the necessary pieces without much difficulty, since the largest thickness of the tinplate reaches 0.7 mm.
  • Hammer with soft striker. You can also use a wooden hammer, a mallet, or a steel tool with a soft rubber lining. However, the last option is used very carefully or not taken at all, as it can cause deformation of a thin sheet of tin and spoil the entire work.
  • Pliers. With the help of this tool solve the question of how to bend a pipe made of tin, because it is steel, although thin, therefore, it is impossible to bend it with your hands.
  • Workbench. This device is necessary when cutting the material and when applying markings.
  • Calibrating element. It can be a tubular product with a diameter of more than 10 centimeters, as well as a corner with a face of 7.5 centimeters. These elements need to be well fixed, since on their surface will be performed riveting of the joining seam.

You should also have a marker, which is a steel rod with a sharp edge, and a ruler or tape measure ready in addition to these instruments.

Making galvanized pipes with your own hands

Factory-made galvanized pipe’s most important feature is its sturdy welding seam.

It matters if you are an excellent welder and own an argon machine at home. You will undoubtedly receive a sight to behold rather than a pipe.

Selecting a galvanized sheet for the pipe is the first step. Experts create bends with walls that are 0.55 mm thick. Simultaneously, it should be remembered that a material is easier to bend the thinner it is.

Tools and materials needed

  • hand scissors on metal;
  • a mallet-peg with a wooden striking part;
  • tape measure;
  • angle;
  • metal ruler;
  • pencil, preferably a construction pencil;
  • pliers.

Provide a straightforward workbench with markings for ease of bending work. Place a steel round mold with the necessary diameter and a metal angle (40 x 40 mm or greater) that is at least 100 cm long on the table.

Cutting out the blank

Think about how to construct a 100 mm-cross-section pipe.

Determine the workpiece’s width:

  • determine the length of the circle as the product of the cross-section by the value of pi, equal to 3.14;
  • 15 mm are allocated for the bends for the connecting seam.

For a 100 mm branch, the total width of the blank cut should be 3.14 x 100 mm + 15 mm = 330 mm.

It is considered that pipes are manufactured with a slight cone shape to facilitate socket method installation. As a result, as shown in the figure, one side is measured at 330 mm and the other at 340 mm.

Profile formation

Mark the bend line for the 5 mm rebate on one side and the 2 mm rebate on the other side of the cut billet.

Arrange the sheet so that its edges line up with the corners of the workbench. Using a mallet, gradually bend it at right angles. The bend is then piled onto the web after the billet has been turned over.

Similarly, bend one edge of the sheet to a length of 10 mm and another to a width of 5 mm.

Afterwards, a mallet is used to manually bend the workpiece on the molding tube.

Processing of the joining seam

Once the workpiece is shaped into a circle, it is placed on a circular mold or another corner and the folds in the lock are joined by tapping the edges with a mallet. The rebates in the future pipe are slightly curved at the narrow end. To seal the rebates, a mallet is used to tap the joint all the way along. The seam becomes nearly indestructible.

Features of the operation of the steel chimney system

Single-circuit pipelines are installed, in most cases, indoors inside brick chimneys and as a separate chimney channel.
The main disadvantage of the system is the formation of a large amount of condensate. In addition, if the design is connected to modern equipment with high efficiency and low temperature of exhaust gases, the rate of condensate formation, as well as the destruction of the pipeline increases.
To improve the situation, it is recommended to make external insulation of the steel pipe with foil non-combustible insulation 5 mm thick. It is fixed with special glue, clamps, foil tape.
With the single-layer pipe, an efficient repair of a brick chimney is carried out. Instead of substantial reconstruction of the stove masonry, galvanizing is installed in the chimney. To reduce condensation, it is insulated with a heat-resistant heat insulator.

In this article, we delve into the benefits of installing a reliable and durable chimney made of galvanized steel for heating and insulation in your home. Galvanized steel chimneys offer longevity and resilience against weather elements, ensuring they endure for years to come. They provide efficient venting for fireplaces and heating appliances while effectively containing heat and preventing heat loss. With their sturdy construction, galvanized steel chimneys require minimal maintenance, saving you time and money in the long run. Additionally, their sleek design adds a modern touch to your home"s exterior. Overall, opting for a galvanized steel chimney enhances both the functionality and aesthetics of your heating system, offering peace of mind and comfort throughout the seasons.

Advantages of galvanized steel chimneys

Condensation is the fundamental foe of all kinds of flue ducts. It builds up inside the pipes and eventually causes them to burst. Manufacturers apply anti-corrosive coatings to them that do not react negatively to moisture in order to prolong. This leads to the production of dependable, long-lasting goods with a low specific weight that can be used for many years. Galvanized steel chimney flues are one type of such product.

They are made in the manner described below. After submerging sections of thin sheet steel in molten zinc, a chemical reaction takes place that results in the combination of zinc and iron molecules to form a robust, damage-resistant layer that is 60 microns thick. This layer gives the steel pipe a long service life and dependable protection against moisture.

These kinds of chimneys also have the following benefits:

  • high fire resistance and resistance to fire;
  • rapidity and ease of installation
  • versatility;
  • a wide range of varieties on sale;
  • rapid heating, providing good draught and, consequently, high heat output;
  • the presence of an additional thermal insulation layer (the product is completed at the request of the customer);
  • smooth inner surface, preventing the accumulation on the walls of soot, soot and a large amount of condensate.

Advice: It’s best to purchase a pipe with an extra layer of thermal insulation if the galvanized steel chimney will be installed in a harsh climate.

Features of the assembly of the gas duct

Following preparation, you can start building the system right away by following this order:

  • Installation of the chimney pipe should start from the heating unit, lead in an upward direction.
  • Gradually build up the sections by inserting the narrower part of the segment into the wider one.
  • The joints of modules should be treated with fireproof sealing compound and connected with clamps.
  • Install fasteners along the entire length of the pipe. The distance between them is determined individually, approximately 1.5 meters.
  • Place an umbrella and cover on top to prevent water from getting on the insulation.

Piping, as you can see, is not difficult to assemble. Although it is better to do it by professionals to avoid various unforeseen situations.Of course, the chimney made of galvanized steel needs regular maintenance: cleaning from soot, sealing small cracks that can occur due to high temperature.
Cleaning can be done independently 1 time a year. A cleaning tool should be used – a pole to which a metal ruff is attached. The diameter of the brush bristles should be larger than the diameter of the pipe. The entire system contour is cleaned through the windows. Finishing cleaning, it is necessary to treat the inner surface of the chimney with an anti-soot composition, which prevents the formation of soot. Finally, the heater must be well heated.
