Metal tiles: what is useful to know about them? How metal tiles are made.

In this article:

Metal tiles are roofing profiled steel with a decorative and protective color coating. This reliable, durable and beautiful view pitched roof every year there is increasing consumer demand in low-rise, cottage, dacha construction. Attracts people spectacular appearance simulating natural tiles; lightness of the metal, allowing you to save on power roofing structure, foundation, affordable price and ease of installation.

The growing pace of low-rise construction (10-14% annual growth) and the gradual change in consumer demand for outdated coatings (slate, roofing felt) towards durable and beautiful ones metal roofs suggest that every year the demand for metal tiles will grow steadily.

Legal registration of production

To start the production of metal tiles, it is recommended to choose LLC as the form of ownership for the legal registration of the future enterprise. The taxation system is on a general basis.

When registering, you must indicate the following code for the main activity: 27.33 “Production of bent steel profiles.”

Sales of metal tiles are planned to be carried out in three ways:

Wholesale sales to dealers, construction depots, specialized construction supermarkets;
Retail sales, work on special orders;
Wholesale and retail supplies to construction stores.

Therefore, it is necessary additional types activities with the corresponding codes: 51.53.24 " Wholesale other building materials", 52.46.73 " Retail metal and non-metallic structures, etc.”

Metal tiles are not subject to mandatory certification, but in order to undergo voluntary certification and receive the appropriate quality certificate, it is necessary to adhere to standards during production GOST 24045-94.

Features of choosing a room for the production of metal tiles

The room for the production of metal tiles must be heated (not lower than +4 C°), be connected to all communications, be divided into a warehouse and production area, and have access roads for trucks. When choosing a room by area size, you should take into account the dimensions of the standard line 15 x 2.7 x 2 m (length-width-height) and storage features that do not allow storing packages of sheets in multi-layer structures to avoid damage to the coating. That's why the optimal size of the mini-plant area with one operating line is 250-300 m2.

Other requirements:

flat floor surface with concrete covering;
lifting special equipment;
380V power supply.

Metal tile production technology

Full technological process production of metal tiles(production of sheet steel, hot rolling, galvanizing, coating with protective anti-corrosion layers and subsequent running through a metal bending machine, cutting and packaging) is quite complex, so only large factories do it.

For small and medium-sized enterprises, the production of metal tiles using the cold rolling method involves the following technological process:

1. Ready-made galvanized sheet steel roll with polymer coating installed on the unwinder;

2. The beginning of the steel strip is passed through the front rollers of the rolling mill;

3. The automatic control system (ACS) is given a program with the necessary parameters (sheet length, wave height, wave step width, etc.). Maximum length sheet - 8 m, but such sizes are made exclusively for special orders, since the length increases the risk of refraction during storage, transportation and installation. The optimal length is 4 m, the width in any case is standard – 1250 mm;

4. By pressing the button the line starts. The sheet, passing through the rollers of a metal rolling mill, is subjected to longitudinal rolling with transverse stamping, and takes the desired “wave” shape;

5. Hydraulic shears (guillotine) cut each sheet of metal tile in a figurative manner in accordance with the wave pattern along the length programmed by the operator, after which the finished sheet is fed to the receiving table;

6. On a pallet, the sheets are stacked into bundles for subsequent packaging and storage.

7. Metal tiles are packed into pallets, secured to wooden pallet using a metal wire. To avoid damage decorative coating During transportation and storage, the sheets should be lined with paper or plastic film, protecting the sides of the stack with cardboard spacers.

Metal tiles are made from profile steel, onto which a special protective covering different colors With decorative properties. Owners of cottages and private houses are increasingly choosing this building material. In country house construction, its popularity is due to its appearance, reminiscent of natural tiles; the lightness of the metal, which significantly saves on the power of the structure; at an affordable price and ease of installation. A roof made of metal tiles () is the key to the reliability, durability and beauty of the structure. Buy metal tiles You can find it at any specialized hardware store.

Metal tile manufacturing technology

This multi-step process requires deep knowledge and is understandable only to specialists. That is why only large factories equipped with modern technology are engaged in manufacturing. The production technology of metal tiles has always remained unchanged, only certain stages were adjusted and improvements were made by manufacturing companies. However, constant changes to this day most likely concern the stages of applying a polymer protective coating. This is directly related to the regular emergence of new types of technological polymers, changes in which also affect the properties of the product. We can say that simple roofing materials have begun to give way to more modern high-tech tiles.

Equipment for metal tiles

The material is produced on automatic and semi-automatic equipment. Included in price professional equipment, which at the output produces a minimum of defects and a maximum of quality and on which also depends price of metal tiles, includes:

rolling mill,
roll unwinder,
roller knife designed for cutting lines,
curly scissors for cutting sheets,
stamper-former,
automatic stacker,
table for receiving products,
equipment installation,
training.

Metals for metal tiles

Products are made from cold-rolled hot-dip galvanized coiled steel. It is installed in an unwinder that passes the material through a lubricator. At this stage, both the quality of the metal and its thickness are important. The rolled steel itself must have a smooth and even surface, since the presence of defects significantly reduces the reliability of fastening the layers. The equipment operates on the principle of preparing metal with a thickness of 0.40 to 0.55 millimeters.

If the manufacture of metal tiles from thin steel reduces the weight of the coating, then, on the other hand, it requires greater care during the installation process. Thick steel, in turn, is difficult to form, requiring the use of specialized production lines. The most optimal steel thickness is 0.5 millimeters; molding is carried out without much effort, and the material is not inferior in its strength.

Metal tile coatings

They prevent the development of corrosion on steel, give the product an aesthetic appearance and eliminates fading under influence ultraviolet rays. It depends on the quality of the coating long term services metal roofs. The polymer coating is applied automatically according to the following scheme. At the very beginning, passaging is done, then a primer is applied, then a polymer coating and protective varnish are applied. The polymer composition is applied only with outside product, from below it is covered with a colorless protective layer.

There are several types of polymer coating:

Polyester with high degree wear resistance and strength and allows the formation of sheets already covered with a protective layer.
Pural, which has a silky-matte structure, but due to its thickness is less resistant to molding, but is more resistant to external factors.
Plastisol, which has a wide color scheme and resistant to temperature and mechanical influences, but not protected from fading.

Production technology

The metal tiles on which the protective coating is applied receives the corresponding profile after entering the molding mechanism. On by next stage the sheet is cut into required sizes and packed. In small and medium-sized enterprises, produced by cold rolling, it passes following technological processes:

A roll of galvanized steel with a polymer coating already applied is placed on the unwinder.
The steel strip is installed on the rollers of the rolling mill.
You need a program with the appropriate parameters.
After pressing the button automatic system control starts.
The sheet passing through the rollers of a metal rolling mill is subjected to longitudinal rolling and takes on a given shape.
At the next stage, each sheet is cut using hydraulic shears in accordance with the pattern programmed by the operator.
Next, the sheets are fed to the receiving table, folded for packaging and storage. For these purposes, special strips and polyethylene film are used for safe transportation products that are fixed with metal bands on a wooden pallet.

How to cover a roof with metal tiles?

The customer, thanks to a wide range of shades, can choose any suitable color roofs, depending on the appearance of the structure. The main indicator when choosing is the shape of the roof, that is, its architectural design. For each shape, a different metal profile size is selected. To determine the size, it is carried out careful measurement of roof slopes. The sheets are laid on the sheathing with the edges protruding by 40 millimeters. During the process of covering the roof, make sure that there are no distortions in the sheathing and rafters, otherwise the appearance of the structure may completely deteriorate beyond the possibility of further repair. The boards used to organize the sheathing are processed with a special antiseptic. The distance between them should be approximately 350 millimeters.

Before laying the sheathing under it on the rafters, it is necessary to lay water vapor barrier layer- the material is overlapped from the eaves to the ridge. The installation process must begin with laying the sheets on the end sections. This type of installation concerns gable roof, and for a tent, the sheets are laid starting from the high point of the slope and on both sides. The installation of sheets is carried out with their initial fastening with self-tapping screws to the ridge, with final alignment along the eaves. Self-tapping screws with an octagonal head must be painted to match the metal tile used. They should have a sealing rubber washer. On square meter steel profile approximately seven pieces of self-tapping screws are consumed.

The construction industry is one of the most developing areas manufacturing business. A popular industry with relatively low costs is the production of roofing coverings. At proper organization and the development of a sales network, the production of metal tiles can bring net profit already for 2-3 years of work.

First you need to consider the stages of manufacturing this roofing material. The main condition is production room. Its area should accommodate everything necessary equipment, warehouse and transport structures of the company.

Main stages of production

The analysis should begin with familiarization with the stages of metal tile production. There are two manufacturing methods depending on the characteristics of the raw material - steel sheets. For small volumes, in order to minimize the cost of purchasing equipment for production, it is recommended to use metal that has already been coated. Its cost will be higher than that of a simple galvanized strip, but production time will also be reduced.

Formation of blanks. For this purpose, rolled steel sheet is used. The main equipment during this stage is the unwinding unit.
Application of passivation coating and priming. Necessary for better adhesion of the metal to the polymer layer.
Installation of the main protective coating. For this, polyester, pural or plastisol can be used. To give a certain shade, dyes are added to the composition.
Stamping and cutting. This function is performed by a multifunctional rolling mill.
Preparation for storage and transportation. At this stage the surface is covered protective film, and markings are applied to the metal tiles.

This is the basic manufacturing scheme roofing, which can be changed and supplemented depending on technological requirements. Each of the stages should be considered more carefully.

Preparatory

The main determining indicator of the quality of the future roofing covering is the original material of manufacture. Cold-rolled coiled steel with a thickness of 0.4 to 0.8 mm is best suited for this. Galvanized coating provides additional protection against premature rusting. In order to cut the workpieces, an unwinding machine is needed, without which the production line is impossible.

Using a loader or similar devices, the steel roll is installed on the rod. There are bearings inside it for free rotation. The beginning of the sheet is installed in the unwinding line before feeding for subsequent processing. For this process, it is important to consider such factors.

Sheet arrival speed. The production capacity of the entire line depends on this.
If galvanized steel is used without a protective coating already applied, it is necessary to provide lubrication of its surface. The best solution for this is special oil sprayed using high pressure nozzles.
If a continuous production cycle is envisaged, it is recommended to purchase an unwinding machine with two drums. As one roll is used, so as not to delay the process due to replacement, a pre-installed second one is connected to the line.

A guillotine knife should be used for cutting. It must be designed for a certain metal thickness, otherwise unevenness may form along the edges of the cut.

Application of a protective layer

It should be noted right away that this requires a special machine for the production of metal tiles. After the workpieces have been formed, they enter the surface treatment stage.

This is necessary to give the metal tiles not only a unique color shade, but also to protect them from external weather factors.

Passivation

This is the general name for all the additional layers installed on top of the metal layer. The main problem with this process is the possible delamination of materials that are different in nature. Therefore, it is important to choose the right primer.

Padding

Using rollers, a primer layer is applied to the sheet, the thickness of which depends on the model of metal tile. It bears only the operational load and does not affect the appearance.

Polymer coating

This is the most important stage in production, since the quality of the roofing material will depend on it. Currently, the following polymers are most popular.

Polyester. A truly universal coating, the thickness of which can be up to 25 microns. It has good flexibility, which is important during transportation and installation of metal tiles.
Pural. Compared to polyester, it is characterized by better mechanical strength. Maximum permissible thickness may be 50 microns.
Plastisol. It is necessary if there is a high probability of mechanical load affecting the surface of the metal tile. Despite the large thickness (200 microns) it has one significant drawback– gradually deteriorates under the influence of UV rays.

The characteristic shade and matte (glossy) surface of metal tiles are achieved by adding additives. Their characteristics and composition are individual for each production process. Almost all big manufacturers keep them secret.

Rolling mill and stamping

After applying the protective layer, it is necessary to give the sheet the appropriate shape. A rolling mill is designed for this purpose, inside of which there is a system of rollers. As the sheet moves slowly, controlled deformation occurs, resulting in the surface acquiring the characteristic tile shape.

Subsequently, the metal tiles are cut to the required length. When drawing up a production flow diagram at this stage, you should take a responsible approach to the selection of such parameters.

Distance between waves. It can be 300 to 450 mm. Most often, the equipment is configured for the production of metal tiles with a distance of 350 mm.
The bending height can vary from 20 to 39 mm. It directly depends on the thickness of the metal - the larger this parameter, the higher the profile of the product can be.
Cutting device. Its shape should completely follow the curves of the metal tile. Otherwise, the edges will not match the rest of the surface.

Depending on the choice of these parameters, you can make almost all types of metal tiles. All dimensions must be strictly observed. For this purpose, the rolling mill is equipped with control sensors that signal any change in the configured parameters.

Packaging and warehousing

Before packaging and storage, metal tiles are marked. You can find out the date of manufacture and determine the person responsible if a defect is detected. This is one of the effective tools when dealing with complaints.

To store roofing coverings they make wooden pallets. They have blank side walls and a lattice top (bottom). Polyethylene film does not protect the entire surface of the sheet. Be sure to leave holes to remove condensation. Warehousing must only be carried out according to the rules.

Production of modern building materials, - this is, as a rule, technologically difficult process, which includes several levels of processing. Of course, the consumer does not need to carefully study all the nuances of metal tile production technology, but knowledge of the basics of production will help to better understand the properties of the material. Therefore, it is worth reading and watching how metal tiles are produced - the video material will give an idea of the main points of the production process.

The roof covering is subject to special requirements in terms of reliability and service life. In addition, there are certain requirements for the appearance of the roof; it should harmoniously complement general design Houses.

When choosing metal tiles as a roofing covering, homeowners accept correct solution. To better understand the properties of this popular material, it is worth getting acquainted with the basics of the technology by which it is produced.

Materials for the manufacture of metal tiles

The quality of the material depends not least on the quality of the raw materials. Metal tiles are multilayer material, the structure of the material is as follows:

The basis of the material is a sheet of metal with an anti-corrosion coating.
The base is coated on both sides with a special primer, which ensures reliable adhesion of the coatings to the steel base.
The upper part of the metal tile – color coating made of polymer material.
The lower part of the sheet is covered with a layer of protective varnish.

Metal used for the production of metal tiles

In most cases, the basis of metal tiles is cold-rolled steel with zinc coating. This material is produced in rolls. Various manufacturers can use steel of different thicknesses to produce metal tiles.

In most cases, metal tile manufacturers use rolled steel with a thickness of 0.45-0.55 mm. However, there are exceptions:

Metal tiles produced in Sweden are often made from 0.4mm thick steel. Such a thin base provides the material with less weight, however, you will need to work with such metal tiles especially carefully, since the sheets are easily deformed.
Some domestic producers On the contrary, 0.7 mm rolled steel is chosen for the production of metal tiles. This solution gives the material greater strength, but such a thick steel sheet is less susceptible to the molding process. In addition, the thicker the base material, the greater the likelihood of deviations in geometric dimensions, and this creates difficulties in making joints on the roof.
Thus, the most convenient material to use is metal tiles with a base thickness of 0.5 mm. This material is quite durable, but at the same time, molds well.

Advice! In addition to steel, other metals are used to produce metal tiles - aluminum and copper. However, despite excellent performance qualities, aluminum and copper metal tiles are not widely used, as they are very expensive materials.

Protective coatings

Steel is a fairly strong material, but it is susceptible to corrosion, so the base of the metal tile must be well protected from external influences.

Advice! A protective polymer coating not only prevents the development of corrosion, but also gives the coating an attractive appearance, since the polymer mass can be painted in any color.

Basically, modern manufacturers use the following types polymer coatings:

PVDF is composite coating, which consists of 8 parts polyvinyl fluoride and 2 parts acrylic. The coating is applied to the base with a layer thickness of 27 microns. The coating has a glossy surface and can be painted in various shades with a metallic sheen. The polymer is characterized by a high degree of resistance to mechanical stress, resistance to fading and other external influences. In addition, the polyvinyl fluoride coating has the ability to self-clean.

Advice! Materials with PVDF coating are the most resistant, so they are allowed to be used even under the most severe climatic conditions, including in the construction of houses on the sea coast.

Production process

For the first time, metal tiles were produced at industrial enterprises started about 50 years ago. The production technology itself has undergone few changes since then. The only aspect of production that is constantly being improved is the application of a protective and decorative polymer coating.

This is due to the fact that new, more resistant types of polymers, as well as protective varnishes and coatings are constantly being introduced into production. Modern factories use special equipment for the production of metal tiles - bending and profiling:

The design of the future metal tile will depend on what equipment will be used for stamping the profile:

The prepared metal is installed on the unwinding mill of the stamping line, from where the base will be fed to the rolling mill;
Here the sheet is given the required rectangular shape;
Then stamping is performed, that is, a transverse profile of the sheet is formed.

Used in production automatic lines for the production of metal tiles. The necessary parameters are set on the control panel, after which the equipment is stamped automatically.

Basic rules for working with metal tiles

Having become familiar with the basics of production technology, the consumer can easily understand how to work with metal tiles. The main requirement is the preservation of the protective layer covering the metal.

If the protective coating is damaged in certain areas, then soon enough a rust stain. This will not only spoil the appearance of the coating, but will also lead to its premature destruction. When working with metal tiles, the following rules must be observed:

Advice! When cutting sheets of material, you also need to take care of safety itself. Safety glasses and gloves must be used.

So, the production of metal tiles is a multi-level and rather complex process. Thanks to the use of modern equipment, the main production processes are automated. This provides high level quality of the material. Knowledge of the basic production processes allows the consumer to better understand how the material should be handled so that the coating lasts as long as possible.

Metal roofing, the installation technology of which will be described in the article, is an excellent solution if you want to create both a cold and warm roofing system.

Features of roof arrangement

If there is a need for installation warm system using tiles, the slopes will have to be insulated. This will allow you to get attic room, suitable for life. It is imperative to provide protection against condensation that may occur on the internal surface of the system. In order to prevent such phenomena, it is necessary to use waterproofing, which is often used as a membrane, which outperforms films in the fight for quality, because the membrane is permeable to steam, which prevents the accumulation of water. When using such superdiffusion materials, you will have the opportunity to significantly save space, because the installation of the panels should be done without providing a gap.

Additional materials

Metal roofing, the installation technology of which is described below, requires initial insulation of the valley. You need to start doing this from the top. The joints at the junctions and the valley must be removed with construction tape. In the case of rafters, the insulation should be laid from the eaves to the ridge, while the panels should be rolled out from left to right. The joints of adjacent rolls must be laid on the rafters, making an overlap of 15 cm wide. The sagging of the sheets must be eliminated.

After you have finished with the waterproofing, you can proceed to laying the thermal insulation layer. As a rule, this is used basalt wool, however, you can choose the material yourself. Insulation mats are installed between the roof rafters. If there is a need to lay several layers, then the installation will have to be carried out by bandaging the seams. This means that the seams of the first layer must be overlapped by the slabs of the second layer. Otherwise you will end up with cool air coming through.

The next layer will be a vapor barrier. Its purpose is to ensure that vapors coming from the interior of the premises do not linger in the insulation and do not turn into water vapor there.

Installation of cold roofing using tiles

Metal roofing, the installation technology of which must be studied before starting work, can be cold. In this case, the slopes are not subject to thermal insulation. Insulation is applied only to the lower area attic space. This ensures that the house will remain warm, while the under-roof space will be well ventilated.

In addition to membranes, cold roof made of tiles can be mounted using a waterproof film. It is laid with some sagging: there should be approximately 20 mm of sagging between the rafters, this will facilitate the drainage of accumulated condensate. In this case, the waterproofing is also laid horizontally, it is necessary to move from the eaves to the ridge, while ensuring an overlap of 15 cm.

Creating a sheathing system

A roof made of metal tiles, the installation technology of which should be known to the master, requires the presence of lathing. For its installation, it is recommended to use 50x50 mm bars, as well as edged board 32x100 and 50x100 mm. At the bottom of the slope - along the cornice - two boards with a section of 50x100 mm should be strengthened. Afterwards, a counter-lattice is laid on top of the insulation, where 50x50 mm bars should be used. They must be fixed along the rafters, starting from the ridge and gradually moving towards the bottom.

Next, you can begin installing the sheathing, which is fixed on top of the counter-lattice. The system elements must be fastened horizontally. The distance between the boards depends on the profile of the roofing material.

The upper area needs to be made somewhat stronger. This is required for metal roofing. The DIY technology involves fixing two boards on each side of the ridge strip. In the valley area, the sheathing should be installed so that it is continuous.

Laying metal tiles

If it is planned to construct the roof in such a way that the sheet of metal tiles will completely cover the slope, then the fastening must begin from the ridge. The first sheet should protrude about 5 cm beyond the cornice. After that, you can begin fixing the sheets of roofing material. In this case, overlap must be ensured. After you manage to install three sheets in their place, you should check the correctness of their position in relation to the cornice. Such analysis should be carried out at the same frequency until the completion of the work. The technology for installing a metal tile roof involves the use of self-tapping screws as fastening fittings, which are screwed into the base of the profile wave.

Features of installation of end strips

End elements should be installed from the end of the roof. They must be fastened with self-tapping screws, observing a step of 60 cm. In addition, an overlap has to be made, the width of which is 50 mm. As ridge strips You can choose flat or rounded elements. The first assume the need for additional fixation of the plug to its own end. It can be regular or conical, and fixation should be done with rivets; there is an alternative solution - self-tapping screws. Before proceeding with the installation of the planks, it is recommended to lay a seal under the ridge, which can be figured or universal.

Additional items

The technology for installing metal roofing involves the installation of ventilation outlets in the spans between the rafters. If the house has a ventilation system, then its outlet should initially be combined with the riser. A corrugated pipe is used for this. To install a passage element on the roof, you must cut out and remove the roof covering element. After laying the insulation, sealant, and sealant, the outlet of the ventilation system must be inserted into the hole formed and attached to the tile with self-tapping screws.

Chimney device

If you decide that your house will have a metal tile roof, the technology, chimney and all other elements according to which it will be equipped must be carefully studied. So, in order to aesthetically bypass the chimney pipe, the latter can be plastered and properly connected to waterproofing. The sheets of tiles that are located on the sides of the outlet must be marked and carefully cut along the stamping line, while maintaining a 15 cm step from the material to the pipe. Now you can install the aprons. Initially, it is recommended to complete the work with the side elements and only then proceed to the rest. When fixing aprons located on the side, it is necessary to ensure that at least one wave crest of the sheet overlaps. This indicates that the side that is in contact with the roof should be 20cm or more wide.

Installation of a steel frame before installing metal tiles

Your metal tile roof can be installed. To do this, you should use I-beams, channels and angles, which are based on profiled metal. The shape of these elements can be triangular, rectangular and trapezoidal. Before purchasing the components of such a frame, it is necessary to take into account all its positive and negative aspects. Among the former, one can highlight durability, while among the latter, there is the difficulty of transportation and more impressive labor costs during installation, which is associated with significant weight.

Using steel roof trusses, you will be able to overlap spans of 50 m. As a rule, these components of the system are installed on top of trusses, which are located under the slings and have a rectangular shape.

Formation steel frame must be carried out after installation of supports made of steel or concrete pads, reinforced with reinforcement and fixed to brick wall. installation of which should be known to you before starting work, is secured in the area of steel rafters with metal gussets, welded or tightened with bolts. All these recommendations are justified for a private developer, while professional companies use hot-rolled pipes, the profile of which can be completely different. Such pipes have very little weight, which is explained by the use in their production of material whose thickness does not exceed 5 mm. This is much less compared to the metal that is used in the manufacture of other profile products.

Features of installing a dormer window

If you decide that your house will have a metal tile roof, the technology and the dormer window unit by which it will be designed should be well studied by you. It is necessary to take into account that the frame for this roofing element will also be needed, and it will have to be sheathed using the same technique that was described above. It is necessary to make a window sheathing system in parallel with the installation of the main frame. The dormer window must have the same rafters, sheathing and ridge. During the installation of rafters at those points where dormer windows are supposed to be located, it is necessary to provide openings enclosed by rafter legs. This will strengthen the system. After on rafter legs cross beams need to be installed. It is recommended to fix it on the beam located below vertical racks, connected to the cross bar. The frame must be mated to the upper beam. This will create a window frame.
