Types of metal profiles for use as roofing and wall covering. The main dimensions of the metal profile The metal profile has a large number of advantages

All types of metal profiles, which are long products with different cross-sectional shapes, are produced by rolling a sheet.

Product advantages

• Strength.
• Ease.
• Profitability.
• High speed of installation.
• Long service life.

These properties of profiles make it possible to use them in the construction of buildings and in their decoration of various levels of complexity. In this case, a load-bearing design is required.

The types of deformation of metal profiles from loading are elastic and plastic. The latter is irreversible and should not be allowed as it leads to structural failure.

Metal profile: types

Depending on the purpose, profiles come in different shapes and manufacturing methods. They must be protected against corrosion by means of zinc and other coatings.

1. Profile pipe

The profile is a hollow product with a cross-sectional shape in the form of a square, rectangle, oval, polygon. It is intended for outdoor construction and finishing works. Various metal structures, doorways, floor beams, rafters are erected from it.

The profile is analogous to wood or It is produced by cold or hot deformation of sheet metal. The complexity of manufacturing significantly depends on the size and thickness of the walls. Welding is mainly used, but there are also seamless products obtained by deformation of a round pipe.

Steel of various grades and aluminum alloys are used as the material of the profiles. The width of the products is 10-180 mm, and the wall thickness is 1-12 mm.

The types of metal profiles are diverse, but products of square and rectangular sections have the highest bending strength. Compared to hot-rolled section steel, the consumption is 20% less. In this case, the surface area in contact with the atmosphere is 40% less. This means less corrosion protection is required.

Installation of profiles is carried out by means of electric welding, but you can use clamps and other fasteners. Metal structures are lightweight and highly durable.

In everyday life, profiles of small sizes and simple shapes are used, and in industry - a wide variety of types of metal profiles (photo below).

Profile steel pipe is used in the construction of pavilions, stalls, sports grounds, supports for various purposes, billboards.

The minimum dimensions are suitable for the production of furniture, sports equipment, interior decoration. Profiles with a section of 100x100x6 mm and above are used as load-bearing structures for private houses.

Aluminum products are used when it is necessary to create structures with low weight, ductility and high resistance to corrosion. Their transverse dimensions do not exceed 80 mm, and the corners can be rounded or straight. To increase strength and ductility, they are created with the addition of manganese, copper and magnesium.

2. Profiles for plasterboard installation

Profiles are used for indoor creation. They are distinguished by their cross-sectional shapes and sizes. They are used to make frames for partitions, suspended ceilings, and also used for wall cladding. Mainly, a metal profile for drywall is used, the types of which are as follows:

PS is a strip bent from sheet metal in the form of a channel. It is easily deformed during the production of profiles and can be made by hand using simple machines. Longitudinal ribs are available for rigidity.

PS is intended for the manufacture of vertical posts, partitions or wall cladding. It is mounted in tandem with a suitable guide profile size. Their forms provide for a tight fit with each other. The holes in the walls of the substation are designed for wiring installation.

PN serves as horizontal guides with a U-shape, into which vertical posts are inserted. It also serves as a guide for matching PCBs.

PP is used for wall cladding and in the manufacture of suspended ceiling frames. It is attached to the base with suspensions. It is convenient to purchase profiles for a false ceiling complete with connectors. Then its installation is quick and easy.

The corner profile protects the outer corners of the plasterboard sheathing from damage. The sharp cross-sectional angle allows the profile to fit snugly against the cladding. It is perforated so that the putty penetrates through the holes and firmly holds the metal to the skin.

PG can be convex or concave and can have different radii of curvature. It is used to create arches and multi-level ceilings.

3. Accessories

All types of metal profiles for drywall are fixed using the following accessories.

1. Two-level connector of profiles when they intersect with each other. It is shipped unwrapped and needs to be bent into a "U" shape prior to installation. Fixation is done with self-tapping screws, which are screwed into the perforation.
2. One-level connector "crab" is intended for fastening profiles at their intersection crosswise. It snaps into place on the profiles and is still fixed with self-tapping screws at high loads.
3. Direct suspension is used for fixing racks to walls, as well as when installing the ceiling.
4. A profile extension is used when you need to extend it.

Plasterboard sheets are attached to the profiles with self-tapping screws for metal. Together with the press washer, they are suitable for all types of connections. Their tips are made by piercing or drilling. The frame is attached to the walls with self-tapping screws with plastic dowels, and the suspension to the ceiling - with a wedge anchor or ceiling dowel.

Types of metal profiles for the roof

The roof system of the house is made of steel in order to reduce loads, increase the service life and fire safety.

Types of metal profiles for supporting structures include bent and hot-rolled, but the latter have more weight and consumption (channel, beam, corner). The lathing is also made of steel. At the same time, all metal is protected from corrosion by zinc or other anti-corrosion coating.

Benefits of metal structures

1. Profiled steel is a strong and lightweight material.
2. Fire safety.
3. Lack of deformations inherent in wooden structures.
4. Compatibility with roofing material: corrugated board and metal tiles.
5. There is no waste during installation.

Features of making a roof from a profile

The roof structure must be pre-calculated for strength. To withstand climatic influences, the coating is securely attached to the crate, which is a metal profile. The types can be different, but the most common are galvanized steel hat laths.

Their price is higher than that of similar wooden structures. But they can be cheaper than a bar with the same technical characteristics. Mixed structures made of wood and metal are sometimes used. In this case, you should be aware that condensation on the metal can cause waterlogging and decay of the wood in contact with it. In addition, metal is a cold bridge, and the roof must be properly insulated.

Rafters with trusses are fixed to the walls with anchor bolts and fixed temporarily in an upright position. Then a hat profile is laid across, and a covering is attached to it.

Thermoprofile

The types of metal profiles include a thermal profile, which looks similar to the usual one for drywall. The only difference is that perforations are made in it, designed to reduce heat loss through the holes are staggered. Cutting the sheet allows you to lengthen the heat flux through the metal, which significantly reduces heat loss, and also improves the vibration and sound insulation characteristics of the material in comparison with wood of the same size. The outer beams of the house are erected from the thermal profile, and the facade cladding is made for insulation and thermal circuits for the roof.

Conclusion

When making metal frames, you need to know the types of metal profiles and their purpose.

Also, for their fastening, various additional elements are used to facilitate installation. You should navigate correctly in all varieties and

Convenient in installation and maintenance, as well as an outwardly attractive material made of corrugated metal, is called a metal profile. It is used when arranging the roof, for the construction of fences and gates. Profiled sheeting has been used in the construction industry for a long time and successfully. Every year this material is becoming more popular and in demand. Today, manufacturers offer consumers different types of metal profiles, and each of them is intended for specific work.

The variety of the assortment is striking, despite the fact that the material outwardly seems simple (see photo). To make the final choice and determine which types of corrugated board correspond to the planned work, you need to know their parameters and characteristics.

Types of corrugated board

For different purposes, manufacturing companies make different types. Before buying, first of all, you need to pay attention to the first letter in the product labeling.

If this is H, then such a sheet belongs to the most durable profiled products. The letter means a supporting corrugated board, which has the greatest thickness and height of the corrugation, and additional grooves give it increased rigidity. Because of these characteristics, it is used to create the strongest roof slabs, fences, fixed formwork, heavy containers, workshops, garages, hangars and warehouses, etc. (cm. : " "). It is often used in the manufacture of fences, gates and gates, since the corrugated board marking, which contains the letter H, gives durability and increased strength to structures for various purposes.

The combination of the letters НС means that the buyer is offered a bearing-wall metal profile. This brand of products is classified as a universal type. The corrugation of such a profiled sheet has an average thickness and height. Structural-wall sheets can be used for slabs, roofing, wall cladding and more.

The letter C indicates that the corrugated board belongs to the wall category, which means the use of material for wall cladding. Most often, a heater is pre-laid under it. Despite the fact that the sheets have a small or medium thickness and height of the corrugation, the strength of this material makes it possible in some cases to use it to create roofs.

The letters in the marking are followed by numbers indicating the height of the corrugation on the sheet, expressed in millimeters. For example, C 8 is written on the profiled sheet, which means the material belongs to the wall type, and 8 is an eight-millimeter wave.

Metal profile parameters

When the consumer has an idea of \u200b\u200bwhat the parameters of the corrugated board are, then he can more easily determine the choice of the products he needs, based on the purposes of its use.

The thickness of the profiled sheet is at least 0.4 millimeters (wall grade brands), and the maximum is 1.2 millimeters (for products of the carrier type).

Bearing metal sheets with the greatest thickness, which can withstand increased loads, are used for arranging powerful floors between floors and in industrial workshops. The maximum weight of the corrugated board is 24 kilograms per "square", and the height of the corrugation can reach 114 millimeters, so it fits optimally. Additional ribs and grooves between the waves increase the resistance to stress.

Bearing-wall grades of corrugated board are distinguished by their versatility. is from 7 to 14.5 kilograms per "square" of material surface area. This indicator is average for the weight that has a corrugated board - the types of which are offered today on the building materials market. The same average is the thickness of the bearing-wall product, which is 0.5 - 0.8 millimeters. The same applies to the height of the corrugation wave - more than 8 millimeters. If an increased load on the surface of the material is not expected, then the profiled sheet of such parameters can be used for the roof.

Wall corrugated board is the lightest of all types, since its weight per square meter does not exceed 7 kilograms (more: ""). It is usually used for roofing and wall cladding. As the description of manufacturers testifies to the corrugated board, the thickness of the wall sheets is at least 0.4 millimeters, and the height of the corrugation is up to 8 millimeters. In the event that the roof coverage area is small and has steep slopes, such a roofing option will be optimal. It will also be an excellent material for building fences or fences (more details: ""). This brand of corrugated board - the texture of which has a decent appearance, is often used in the construction of private households.

The most popular brands of metal profiles

Despite the huge range of products manufactured, there are the most popular brands of corrugated board.

Moreover, each specific type of product is used for specific purposes:

• N-60 - has a weight of 5 - 12 kg / m², the thickness of the profiled sheets is from 0.5 to 0.9 millimeters, the height of the corrugation is 6 centimeters. It is used to create load-bearing structures and for roofing, often used in the construction of fences, fences, garages;
• N-75 - sheet weight - 9.2 - 12.0 kg / m², thickness - 0.7 - 1.0 millimeters, wave height - 7.5 centimeters. Refers to universal products used for various construction work. Performs not only bearing functions, but also protective ones. Such corrugated board is used for roofing and installation of floors;
• N-114 - weight 10.2 - 14.5 kg / m², sheet thickness from 0.7 - 1.2 millimeters, wave height - 11.4 centimeters. It has additional grooves to increase resistance to loads, the effective texture of the profiled sheet surface provides an attractive appearance. Designed to create the most durable structures and for other purposes;
• N-153 - such a brand of professional sheet is often called the European standard. Sheet weight - 10.3 - 21.5 kg / m², thickness - 0.7 - 1.5 millimeters, wave height - 15.3 centimeters. It is popular due to the ability to install on surfaces, the pitch of the crate for which is up to 9 meters;
• N-158 - such a brand is popular due to the presence of the highest wave - 15.8 centimeters and the ability to use it on surfaces for which the crate is built in steps of up to 9 meters. Sheets have maximum rigidity and strength. This brand of profiled sheet is ideal for creating many types of structures.

Roofing metal profiles - types of material "). A durable option is to cover their polyester, especially since it is available on the market in a wide range of colors. Adding Teflon to polyester makes the protective layer stronger. Reliable are PVDF coatings and a mixture of PVC and various additives.

When building a house, one of the last steps is roofing. For this, you can use different materials, for example, tiles, as well as slate. But a more modern and reliable option is a metal profile. Due to its qualities, this material has become widely used in many countries of the world, not only for laying roofs, but also for making a fence. In this article, we will talk about the metal profile as a material for laying roofs, and will also give detailed step-by-step instructions on how to calculate the required amount of metal profile for the roof.

What it is

A metal profile (also corrugated board) is a sheet metal material that resembles slate in appearance, and is very durable with a low weight. This material is most often coated with galvanized steel. During its production, the corrugation process takes place, during which the corrugated board acquires a wavy appearance, like that of slate, and becomes more durable from this.

The height and size of the waves can be different.

Pros and cons

The metal profile has a large number of advantages:

1. Price.For the manufacture of corrugated steel, galvanized steel is used, which is a completely economical material. Therefore, the cost of corrugated board is also low. This is one of the most important qualities of this material.
2. Ease. In order to bring this material, it is not at all required to hire heavy equipment, since it is a fairly light material.
3. Strength. Unlike other materials, metal profiles are very durable even at low weight. As already noted, strength is also imparted by a wavy shape.
4. Corrosion resistance.In the manufacturing process, the corrugated board is covered with a special polymer layer, which makes the material highly resistant to corrosion. Other metallic materials are susceptible to this destructive effect, which can negate long hard work.
5. Resistant to weather conditions. The metal profile can be used in any weather conditions; this will not decrease its quality at all.
6. Wide range of uses. Due to its qualities, this material began to be used not only for laying roofs, but also for the construction of fences and other fences, as well as for ceilings and for wall decoration. Due to its lightness, this material does not require any special technique when working with it, which again saves money.
7. Colour. This is also one of the main advantages of a metal profile. Decking can be of a wide variety of colors and shades, which allows you to be creative with roofing. These are the advantages of the metal profile. Of course, there are also disadvantages, but with so many pros and cons, there is only one:
8. Thermal insulation.Decking is not able to provide thermal insulation. But this drawback is completely eliminable, because heat-insulating material can be bought at any hardware store and trim the roof with it before starting to fix the corrugated board.

Kinds

Decking can be classified according to various parameters, the most basic of which are classification by purpose.

So, by purpose, the material is divided into three types:

This type is most often used to install fences and other protective structures. Its main purpose is external and internal wall cladding. It is also used for the construction of pavilions, kiosks and stalls. Thickness usually ranges from 8-9 mm to 36 mm.

Carrier. This type is usually marked with N. It is most often used for interior and exterior wall cladding, as well as for the construction of garages and carports.

Roofing. This type of corrugated board is mainly used for roofing. Unlike other types, the roofing metal profile has higher corrugations, which undoubtedly increases the bearing capacity. This material is produced by rolling hot-dip galvanized sheet through special machines. In this case, the rollers of the machines are adjusted in such a way that as a result, sheets of a wide variety of shapes can be obtained. According to its characteristics, roofing decking is in many ways superior to metal tiles.

The size

The corrugated board is made of steel, which is initially wrapped in a roll. Therefore, the length of the profiled sheets can be different, and this will depend on what length the customer ordered. But the width of the sheets is usually 900-1800 mm.

The thickness of the sheets also varies, but the standard values \u200b\u200bare 0.5 mm, 0.55 mm, 0.7 mm, 0.8 mm and 1 mm.

There is one more characteristic - height. The height of the profiled sheet is the distance between the extreme points of two corrugations, which are considered to be adjacent corrugations in relation to each other. It should be noted that if there is a desire to show a volumetric roof, then the height of the profiled sheets should be high.

How to calculate the material

Before you purchase profiled sheets for roofing, you need to calculate how many of these sheets and what size will be needed.

There are two ways to calculate:

1. Calculation using special computer programs.
2. Self-calculation.

The first has a number of advantages over the second method:

1. Allows you to give an accurate result.
2. You can calculate the amount of material for roofs of the most complex structures, taking into account all, without exception, overlaps and roof slopes.
3. During the calculation, you can change certain parameters, which will allow you to get the most optimal result.
4. The programs also provide the ability to select the color and other characteristics of the profiled sheets.

Such calculation programs can be downloaded from the Internet completely free of charge, or you can use online calculations, where you need to enter the necessary data in the empty fields, after which the system will give you the result. An independent option is also a good option, but experts recommend a computer method, since there is a risk of making mistakes in an independent calculation, especially if the roof has a complex structure. Moreover, this method is time consuming.

Here are the basic principles:

1. You need to calculate the width of the sheets. In general, there are two widths:
   • Full 1180 mm.
   • Useful 1100 mm. The thickness and weight of the profiled sheets should also be entered in the calculation table. These values \u200b\u200bare specified with the seller.
2. Then the number of profiled sheets is calculated. To do this, the length of the roof slope is divided by the working width of the sheet, which is 1100 mm. The overlap is 80 mm (1180-1100 \u003d 80 mm). But: the amount of vertical overlap depends on the brand of the profiled sheet, as well as on the step of the wave. All these parameters should be checked with the seller.
3. Now you need to decide on the number of horizontal rows. To do this, take into account the total length of the roof slope (the eaves overhang is also included in this length) and the length of one sheet. The eaves overhang is also specified with the seller or specialist.
4. Then the size of the horizontal overlap should be selected. This value depends on the angle of inclination of the roof. There are several options:
   • If the tilt angle is 15 degrees or up to 15 degrees, then the horizontal overlap is approximately 200 mm.
   • If the angle of inclination is on average from 15 to 30 degrees, then the horizontal overlap is taken from 150 to 200 mm.
   • If the overlap angle is more than 30 degrees, then the overlap is taken in the range from 100 mm to 150 mm.
5. Now it is necessary to take into account additional (additional) elements of the roof. When calculating additional elements, you need to add up the lengths of the profiled sheets on which they will be installed, and the result must be divided by 1.9. The overlap of the additional elements should be 100-200 mm.
6. If the valleys are calculated, then the sum of sheet lengths must be divided by 1.7, considering that the overlap should be 300 mm.
7. Fasteners. For an additional element 2 meters long, about 8 pieces of self-tapping screws will be needed. One square meter of the roof will need 7 self-tapping screws.

That's all. This is how an independent calculation is made. It should be borne in mind that this method should be used only if it is required to cover a roof of a simple shape, for example, a garage, a bathhouse, etc. If the shape of the roof is complex, with many projections, then it is necessary to resort to the help of a specialist or to a computer method.

Mounting

Before you can cover roofs with metal profiles, you must first build a crate. It is usually made from wood planks that have been treated with an antiseptic. Then a layer of thermal insulation and waterproofing is laid. You also need to think about ventilation holes, which are usually located in the highest areas of the roof. For air outlet, special gaps are usually used, which are installed between the roof ridge and the slab.

The waterproofing film is laid in the direction from the eaves to the ridge. The film should also be overlapped, and the joints should be fixed with a special glue. After the ventilation system, vapor barrier and waterproofing have been completed, you can put the metal profile on the roof, arrange the sheets according to the calculations, and proceed with the fastening.

Mount

The process of fastening the metal profile to the roof is carried out using self-tapping screws, which are equipped with special insulation and waterproofing elements.

When fastening, you must adhere to the following rules:

1. Self-tapping screws should never be clamped too tightly, but not too weakly. This can lead to the fact that water begins to drain through the resulting gap.
2. Self-tapping screws must be inserted strictly perpendicularly.
3. Self-tapping screws should be tightened at an equal distance from each other in the overlap areas.
4. When attaching the ridge, the distance between the screws should be taken at 300 mm.

If you follow all these tips, as well as the recommendations of experts, then the roof will serve for a long time.

Estimated cost

As already mentioned, the metal profile is an inexpensive material. But it should be borne in mind that the price per square meter of this material mainly depends on the polymer coating. For example, if a sheet is not covered with a polymer material, then it can be purchased at a price of 250 rubles per square meter, and if it is covered with any polymer material, then the price will be over 600 rubles.

In general, the total cost consists of the cost of purchasing sheets and installation work.

If we count that the sheet was bought at a price of 700 rubles per sq. meter, and a certain amount of such sheets was needed, then 700 rubles should be multiplied by this amount. Then you need to add 1000 rubles to the result obtained (the cost of screws, etc.). Now you need to calculate the cost of installation work, such as installing the battens, installing rafters, laying sheets and others. All this as a whole will cost about 1500-2000 rubles.

Then you need to summarize all the results obtained:

1. The cost of purchasing sheets.
2. 1000 rubles (the cost of screws).
3. Installation work costs, approximately 2,000 rubles.

One of the most popular finishing options is surface cladding using sheet materials. Where a metal profile is required, which is used to form a high-strength frame.

When forming the frame, various materials can be used: wooden beams, plastic pipes. However, professionals prefer metal profiles, as compared to other building materials, they are distinguished by high reliability, long service life, ease of installation and universal design.

pros

Useful information:

Why are metal profiles so popular? This is due to their positive technical and operational characteristics, which include:

1. Resistance to sudden changes in temperature and high humidity;
2. High strength and reliability - these parameters are due to the presence of stiffeners in metal profiles and a sufficient metal thickness;
3. Corrosion Resistance Most of the models have a protective, anticorrosive coating (zinc layer or polymer spraying), which allows them to keep their original appearance for a long time even in high humidity conditions;
4. Environmental friendliness of this building material. Do not emit harmful chemicals into the atmosphere;
5. Ease of installation. To use metal profiles in repair and construction work, you do not need to purchase expensive tools. Cutting or bending is carried out using standard devices: metal scissors, grinders, hacksaws;
6. Long service life. With proper installation, metal profiles can serve you for a long time;
7. Unique combination of price and quality. Low cost favorably distinguishes them on the building materials market. The use of metal profiles in repair and construction work will not greatly affect the final budget and will not entail unforeseen material costs.

Types of metal profiles

Today on the market there is a wide selection of metal profiles, with their help it is possible to manufacture structures of various sizes and configurations. Below is a table of main sizes:

The metal has high technological properties, which makes it possible to use it without restrictions in the construction of a wide variety of structures (even with the negative impact of environmental factors).

Applying profiles

Guides (square profiles) - as a basis for fixing ceiling and rack-mount profiles, while the length of a single section is 3 or 4 meters;

Ceiling (T-shaped profiles) - used in the formation of the lathing, which serves as a fastener for various finishing materials. These products have section parameters 60 * 27 millimeters;

Rack (U-shaped profiles) - a frame made of metal post profiles for load-bearing structures and walls. This kind, on the floor or on the walls;

Corner profiles - in quality;

As we can see, the profile is widely used in the construction of residential and industrial buildings for the construction of roofs, walls, ceilings and additional non-residential buildings.

It is impossible to know everything and about everything, especially when you are faced with the problem of choosing a specific product, for example, corrugated board. But this does not mean that you need to take their word for the first source on the Internet.

Remember, we all heard the expression from early childhood "Ignorance of the laws does not absolve from responsibility"... In the process of upbringing, they try to explain to any child that if you have done something illegal, even without knowing that it is bad, then you will still have to answer before the law. The law is harsh, but just or not fair, but harsh? In general, any law is better than lawlessness. The main thing here is that no matter what, God forbid, I had to get acquainted with the court directly. And then, there, as it happens:

In this article, we would like to equip our clients with a set of instructions when choosing corrugated board and metal tiles. The reason, as mentioned above, if you don’t know something, doesn’t mean that you don’t have to answer for it with your money.

Step # 1. Understand your need

What our potential client is looking for is corrugated board, the price of which will pleasantly surprise him. Is it correct? It seems to us that from the beginning it is necessary to ask ourselves what goals I am pursuing, why I need this product, what I want to get at the exit.

For example, let's take corrugated board for a fence. Everyone wants the fence made of corrugated board to stand for a hundred years and with it, no changes occurred.

We start searching. We call and ask about the cost, tell about our wishes. The offers are the most expensive at the beginning, however, the sales managers are trying to get you talking and find out what price they have already offered you. From this moment, the attack begins. Conversations from the category: "Well, why do you need such an expensive corrugated board, take another cheaper one from us, it is no different and even better"... And you start to doubt, but really, maybe he does not differ from each other.

You and only you know exactly what you need. Any advice and advice you need to get an idea of \u200b\u200bthe product and only then make a decision.

It is wrong to make a choice of goods under the influence of emotions. It is not difficult to buy corrugated board for a fence, it is difficult to choose exactly what is needed.

Make a conditional list of questions for yourself:

• How old do I need a fence?
• What is beauty or reliability in the first place?
• What is the design of the fence and is it possible to replace corrugated sheets in it over time?
• What technical characteristics of corrugated board affect the durability of the fence?

And when you determine for yourself what kind of corrugated board you need. Then you can ask questions about its specific characteristics, especially since you are already trained.

Step # 2. Let's understand the characteristics of the metal profile (corrugated board)

Our product, which people call names for everything: corrugated board, metal profile, corrugated sheet, corrugated sheet, profiled sheet, is a universal building material. Before getting into the machine and purchasing the finished product, it is in the warehouse in the form of a roll and is actually a raw material. The technical characteristics of this raw material (roll) affect the quality of the finished product, somewhere by 70-80%. Let's consider them in more detail.

In a series of articles under the general title of the illusion of deception, we dwelt in detail on each point where you can most often be misled. Therefore, now we will pay attention only to the main components.

Metal thickness. Perhaps this is one of the main criteria when choosing corrugated board and metal tiles. This indicator primarily affects the durability of the product.

Not so long ago, rolls of less thickness than 0.4 mm did not come to our country, but, as you know, the market dictates its own conditions. Today's realities are such that a roll of galvanized steel with a polymer coating is delivered with an even thinner thickness, which reaches 0.3 mm.

Of course, such a material is needed, but its scope should correspond to the declared thickness. Everyone wants to be cheaper, but you need to understand that if a metal tile is made from such metal, then in five years it will have to be replaced on the roof.

As an example, it is worth mentioning the real tests carried out by ArcelorMittal in France (Caen area). Two polymer coated steel samples were taken. In one zinc base is 100 g / m 2, in the other zinc base is 275 g / m 2. Both samples were in the same conditions, were located at an angle of 90 ° and secured with screws and rivets. After five years of testing, the following picture appeared before us.

Conclusions are not difficult to draw.

We should have mentioned other important characteristics such as polymer coating thickness, steel structure structure polymer coated, what is the difference standard polyester from matt etc. But we will not do this. And here's the reason.

There is a direct relationship between all characteristics and material cost.

Imagine a car manufacturer. He makes the cheapest car. And suddenly, for some reason only he understands, he decides to install the most expensive and powerful engine on his cheap car, which is installed in the coolest sports cars.

The question is how to sell it? As a cheap car will no longer work, the engine cost too much. As a middle class, it will not work either, the design of the car itself does not allow. Well, how expensive it will not work. In general, the idea failed.

The same happens with the production of polymer coated rolls. What's the point of making thin metal (economy class) and trying to increase the zinc content in it.

For a long time, roll manufacturers have been producing a variety of products, with different characteristics and, accordingly, different price categories. Therefore, it makes sense to divide our product into different price classes.

Step # 3. We compare the cost and the declared parameters

First, we will reveal to you the most terrible secret, of course, not as terrible as this ...

Our little secret, or rather the secret of all manufacturers of corrugated board and metal tiles. It lies in the fact that the cost per square meter of the finished product is the total equivalent of the cost of one ton of a roll + overhead and profit. And this formula is unchanged in relation to all material (economy, standard, elite).

Tell me, why do you buy an expensive roll of maximum thickness with a high zinc content, with a high-quality coating? In order to use it to produce a quality product, for example. It is rare for someone to get the idea of \u200b\u200bmaking fence corrugated board from such raw materials, which is used for temporary fences at a construction site.

Therefore, if some sales illusionist claims that he has European raw materials in a thickness of 0.45-0.5 mm. and zinc content is at least more than 140 g / m 2, and the cost per square meter is less than 50 UAH. Then ask him a problem: how much does a ton of such a roll cost, and how many square meters of the finished product can be made from it?
