At the very beginning, we noted that the article will focus on corrugated sheets. They indicated as an example where it can be used (fencing). However, this is not the entire area where such material can be used.
Builders are familiar with this material. But for the common man, its name may mean nothing. What is a profiled sheet? To answer this question, you can go to the Internet, where a detailed definition is given. To make it clear to everyone, we will give a definition in simple words. Corrugated sheeting is metal sheet, manufactured through the cold rolling process. The second stage of production is sheet profiling. This stage is extremely important, as it gives additional rigidity and strength to the material, which in turn improves its performance. Typically, galvanized steel (galvanized steel) is used to make the sheet. Such steel is less susceptible to various unfavorable conditions which lead to corrosion. Thus, the service life is increased many times over.
An important element in production is the application of a layer(s) of protective coating to the sheet. It can be represented by paint and polymer coatings. As you might guess, it serves not only to give the material a proper and presentable appearance, but to preserve the metal from corrosion, thus increasing its service life many times over.
Before considering the characteristics of corrugated sheeting, let us note the areas of application of this material. It can be used for fencing of all types (in simple words), corrugated sheeting can be used as a material in the manufacture of entrance gates in the private sector or at the dacha, as a roofing covering, the sheets can be used to cover the walls of a building, it can also be used for... This is not the entire list, which can be given as an example. But a wide scope of use is already visible from it. And the wider the scope, the more interesting and attractive this product becomes.

Characteristics of corrugated sheets
When choosing sheets, you should pay attention special attention to the following letter designations. There are such markings: N, NS, S. They mean the following. The product marked H is used as a roof covering. NS – used for wall and roof fences. C – for wall fences. Knowing these designations will help you in choosing the required material depending on what type of work you have planned.
The letter designation is always followed by a number. It can be completely different. It means the height of the profile. Let's look at simple example. The product is labeled C-8. Literally, this is wall corrugated sheeting with a profile height of 8 mm. And so on. Nothing complicated.
The main characteristic of this product is its strength, and, consequently, reliability during operation. Long service life. At correct use the sheets will serve you for many years and will not lose their appearance. However, this point will be observed only if during transportation and installation the material is not subjected to deformation of the protective coating. If there are deep scratches on the product, this should not be ignored. It is better to correct it in time by painting over the damaged area. This way you will avoid corrosion. The service life of various types of polymer coatings is quite long. As a rule, manufacturers guarantee 25-30 years.
The material is relatively inexpensive. In conjunction with high quality and an affordable price can only characterize corrugated sheets from the best side.
The ease of installation of this material makes it doubly attractive. Low weight is also an undeniable advantage. Even one person can easily cope with securing the sheet to any surface. This is especially noticeable when working at height (when installing roofing). Anyone who has covered a roof with slate sheets understands how difficult it is for one person to pile one unit to a height.
Modern technologies today make it possible to easily apply any “picture” to a profiled sheet. The product painted to resemble stone or wood looks very good. At the manufacturing plant, anyone can order any color scheme. However, there are a great many available on the market today.
All of the above positively characterizes the material. While using it, I can say one thing: it has very few shortcomings. The most significant of them include the following. A fairly loud noise that occurs when an object somehow falls onto a sheet. This applies primarily to the product used as a roof covering. A simple example. At your dacha you decided to make a gazebo under the apple tree. The roof of the gazebo is made of corrugated sheets. In the fall, when the apples are harvested and they begin to actively fall, then sitting in the gazebo at this time, you will experience some discomfort when an apple falls on the roof. But you must admit that this is only a special case. Well, another disadvantage is the corrosion of the material when the protective layer is damaged. Well, we already mentioned this.
Any summer cottage plot or private house, as a rule, is fenced. Along with the fence there is inevitably such an attribute as entrance gate. We would like to draw your attention to the fact that from corrugated sheets - great solution. Here are examples of photographic material where you can look various options such a gate.
Everyone chooses the frame of the structure to their own taste. The frame is made as follows. Buying metal profile the size you need. It can be square, rectangular or other cross-section. The profile is cut to the required length. The cut parts are attached to each other by welding. Welds are cleaned grinding disc. The finished frame is primed and painted desired color. This will protect the metal from rust. They can be welded onto the finished frame various elements(curls, petals, etc.). they usually serve for decorative purposes. And finally, to give the gate a finished look, the void (inside the frame we welded) is filled with profiled sheets. It is best to fasten the sheets to the base with special rivets using a riveting device.
Despite the fact that the history of using corrugated sheets in the construction business goes back almost two hundred years, this has not made it any less popular and in demand as a material. And if at the beginning of the 19th century the production of the first profiled sheets was a labor-intensive and economically unfeasible process, since the products were made by hand from wrought iron, then in modern conditions profiled sheets are produced easily and quickly on rolling mills from steel sheets or steel coils.
What is a profiled sheet - its main characteristics, what properties does it have?
A corrugated sheet is a sheet of metal with a corrugated surface (stiffening ribs). It is obtained by cold pressing on special machines. Stiffening ribs (corrugations) are located longitudinally, which allows the profiled sheet to withstand heavy loads. Moreover, the greater the height of the profile, the stiffer the sheet itself. The shape of the ribs can be round, triangular, trapezoidal, and the thickness of the metal also differs. For different types construction work choose different brands this universal material.
In general, profiled sheets are widely used in individual and industrial construction for the construction of fences, roofing, load-bearing structures, formwork, and for finishing facades and walls from the inside. The lightness and strength of the material helps reduce installation time.
Main characteristics of the profiled sheet:
Note . It should be taken into account that the working width of the corrugated sheet, due to the features of its design, is less than the total. Therefore, when preliminary calculations The length of one wave (profile), which goes to overlap, is always subtracted from the total width of the sheet.
What are the advantages and disadvantages of corrugated sheets?
Advantages:
- Relatively low price makes the material accessible to different categories consumers.
- Resistance to temperature changes allows the use of corrugated sheets in regions with harsh climatic conditions. The main thing is to comply with the rules of its operation.
- The considerable length of the sheets (up to 12 m) helps to make a minimum number of joints when arranging the roof.
- The lightweight corrugated sheet rises to a height without the use of construction equipment.
- Even after ten years, damaged material is easily replaced with a similar one.
- Wide selection color range coating allows you to choose any shade of corrugated sheet to create a unified architectural ensemble of the entire building and the surrounding area.
Flaws:
- The low noise insulation of the material and its ability to amplify sound create a “drum roll” effect when it rains. This drawback can easily be eliminated if, when installing the “roofing pie,” it is used as insulating protection. mineral wool.
- If the protective layer of corrugated sheeting is damaged, its corrosion resistance and, accordingly, service life are significantly reduced.
Types of profiled sheets - which one is better?
Depending on the purpose, profiled sheets are divided into 3 groups:
- Wall
Marked with the letter “C”. Used for the construction of fences and interior walls, wall cladding. The height of the corrugation (profile) is minimal and is 8-35 mm, the thickness of the sheet is 4-8 mm.
- Roofing
Roofing sheets are designated by the letters “NS”. This material is considered universal. It is used in the construction of roofs, fences and for other purposes. Sheet thickness is 5-8 mm, profile height is 35-44 mm.
- Carrier
Marked with the letter “N”. It has the largest thickness (8-10 mm) and profile height (57-114 mm). Its strength is enhanced by additional grooves. The material is quite expensive for roofing; it is used in more critical areas. For example, as load-bearing structures and interfloor ceilings during the construction of hangars. The service life of the products is 40-60 years.
For information . When choosing a profiled sheet, you can easily find out the characteristics of the material by markings:
- The first number after the letter C, N or NS indicates the height of the corrugation.
- The second number is the sheet thickness.
- The third and fourth, respectively, are the width and possible length of the sheet in mm.
Example. Marking C10-0.5-750-12000 means wall corrugated sheet with a profile height of 10 mm, sheet thickness is 0.5 mm, sheet width is 750 mm, maximum length 12,000 mm.
Profiled sheet brands:
| Brand of corrugated sheet | Sheet thickness, mm | Profile height, mm | Scope of application |
| From 8 | 0,5 | 8 | Wall cladding, interior decoration |
| From 21 | 0,4-0,8 | 21 | Roofing, building cladding |
| NS 44 | 0,5-0.7 | 44 | Roofing, garages, hangars |
| NS 35 | 0,8 | 35 | Formwork, fences, roofing |
| N 57 | 0,7-0,8 | 67 | Roofing, formwork, ceilings |
| N 60 | 0,9 | 60 | Roofing with spans up to 2 meters, coverings. Load-bearing elements |
| N 75 | 0,7-0,9 | 75 | Roofing, formwork, interfloor coverings |
| N 114 | 0,9-1,0 | 114 | Roof with sheathing 6 m, load-bearing structures |
How to choose the right professional sheet?
I would also like to give some tips on choosing a profiled sheet:
- For the installation of fences and enclosures, a profiled sheet with a wave height (corrugation) of 8-21 mm is suitable. This material includes grades C8-C 21. It is desirable that the products have a durable coating, for example, polymer, otherwise, under the influence of precipitation, the initially elegant design will quickly lose its appearance.
- For roofing, it is better to use material with a profile height of 18-35 mm. Suitable brands are C 18, C 20, C 21, NS 35. The profiled sheet of these brands has sufficient load-bearing capacity.
- There is no point in talking about load-bearing profiled sheets of high grades, since they are usually not used in individual construction.
Advice . When choosing a profiled sheet for a roof, you should take into account that it is better not to use sheets of short length. Large quantity joints will definitely affect the quality of the coating. In addition, material consumption increases due to overlaps and fastenings, and this is a financial component.
Galvanized corrugated sheeting has a fairly wide range of applications.
Typically, structures made from it are installed as:
- Permanent formwork when pouring the foundation.
- Load-bearing structures and interfloor ceilings.
- Temporary or permanent fencing for industrial buildings.
In general, galvanized corrugated sheets are used wherever it is not the appearance of the material that is important, but its lower cost.
Profiled sheets coated with polymers or varnish are used for installation:
- Trade pavilions, kiosks, containers.
- Industrial premises, gas stations, warehouses.
- Cladding of building facades.
- In country and cottage construction.
- For interior work by finishing.
- For wickets, fences and gates.
- For covering roofs in buildings with large spans and increased requirements for specific loads.
For what purposes is it better not to use corrugated sheets?
It would seem that such a universal material as corrugated sheets can be used in all areas of construction under various conditions.
However, there are some installation restrictions for it:
- In an aggressive and humid environment, it is better not to use structures made of corrugated sheets, because this is not an inert plastic that is neutral to water. Metal sheets at the ends are very susceptible to corrosion, which significantly shortens their service life. Therefore, if you want to fence off a manure heap or put bottom part fence close to the ground, at least paint the edges of the sheets.
- It is also undesirable to use corrugated sheets for assembling structures aimed at storing food products. Since the sheets are coated with zinc (even under a polymer coating), it forms toxic salts when interacting with acids.
- It is not recommended to use corrugated sheets to cover a roof without sheathing. Although craftsmen, saving time and effort, manage to nail sheets on top of the old coating. To be sure, I also cover it with cellophane. However, no one thinks that when there is a temperature difference, condensation forms, which is not removed, but is retained under the profiled sheets. As a result, the service life of the roof is significantly reduced.
- As practical experience and SNIPs show, it is not worth covering the roof with corrugated sheets if the roof slope angle is less than 100. During heavy rains or when snow melts, water will flow into the under-roof space.
- It is also inconvenient to work with corrugated sheets when installing a complex roof.
From the right choice Roofing material determines the durability, reliability and ease of use of the roof. However, deciding which coating to use without the advice of an experienced expert can be problematic. Advertising videos and booklets praise some materials, sellers persistently recommend others, which completely confuses the buyer. A roof made from low-quality profiled metal sheets will not last longer; it will bring more problems and repair costs to the homeowner than it will benefit. In this article we will tell you what types of corrugated sheeting for roofing there are, as well as what requirements for this material are regulated by GOST 24045-94.
Profiled sheet is the most popular roofing material for arranging the roofs of utility, outbuildings and industrial buildings, a little less often it is used in private housing construction. Corrugated sheeting, according to the definition of GOST 24045 94, is a material produced by cold profiling from steel. It has a multilayer structure; sheet steel 0.5-1.2 mm thick is used as the base of the corrugated sheet, onto which galvanic zinc coating is applied, and then polymer protective film from pural, polyester or plastisol. All types of corrugated sheets have the following performance characteristics:
- Corrugated sheets used for roof construction have a high load-bearing capacity, which is formed by increasing the number of stiffeners. Corrugated roofing sheets, in accordance with GOST 24045 94, must withstand significant snow loads, as well as the average weight of a person.
- Corrugated sheeting has high corrosion resistance. The polymer coating that covers the sheets protects the metal from contact with liquid, which prevents the appearance of rust spots.
- Fairly light weight. Universal, roofing and wall types Corrugated sheets have a relatively small mass compared to other materials. Sheets size 1 square meter have a weight of only 5-7 kg, for example, the same area of traditional ceramic tile covering weighs almost 17 kg. Light weight material will allow the use of a simple rafter frame for the roof and lattice lathing in increments of up to 30 cm.
- Different types of corrugated sheets are produced with different standard sizes. Most often, the sheets have an overall width of 1250 cm, and the length can range from 1 to 12 m.
- According to GOST 24045 94, the profiled sheet can have 5,6,7 or 8 waves. The most popular are 7 and 8 wave corrugated sheets, since they technical specifications better suited for roofing.
- Versatility. Roofs with a slope of 6 degrees are covered with corrugated sheeting. Experienced craftsmen claim that you can use this material starting with a slope angle of 3 degrees, if you make larger overlaps and treat the joints with sealant.
Pay attention! All types of corrugated sheets produced in accordance with GOST 24045 94 are cut and installed using the cold method, since the protective polymer coating on the surface of the material under the influence high temperature burns out. Installation work with the use of profiled sheets, they are not performed using a grinder, welding or abrasive tools.
Types of material
Corrugated sheeting is a universal material that can be used to perform many construction tasks. To ensure that the technical characteristics meet the conditions of use, manufacturers produce various types corrugated sheets, differing in price, load-bearing capacity, shape, profile height and width, and dimensions. In accordance with GOST 24045 94, there are 3 types of profiled metal roofing:
Important! According to GOST 24045 94, corrugated sheets are divided into categories according to the technical characteristics of the material and purpose. Experienced roofing craftsmen recommend using products marked “H” and “CH” for roof installation. Only corrugated sheeting of these types has sufficient load-bearing capacity to withstand significant snow loads. In addition, the height of the profile allows you to effectively drain melt and rain water from the slope. The universal and load-bearing profiled sheets have a thick polymer coating that protects against corrosion.
Selection rules
Choosing a high-quality material that is appropriate for the purpose of use is the key to a long service life, strength and reliability of the roofing covering. Without the help of a professional craftsman, it can be difficult to understand which corrugated sheeting is better. In order not to get confused in the wide range of corrugated sheets, focus on the following indicators:
- Product compliance with GOST 24045 94 or other technical regulations, accepted by the corrugated sheet manufacturer. Certification of roofing profiled sheets is a voluntary procedure, but the presence of such a certificate of conformity serves as a guarantee of the integrity of the manufacturer and the quality of the material.
- Purpose. The material must match the installation location, so you need to use universal or load-bearing corrugated sheeting for the roof, and wall sheeting for fences.
- Material thickness. To construct the roof, corrugated sheeting with a thickness of 0.8-1.2 mm is used, since it has sufficient strength to withstand the weight of a person and snow during the heaviest snowfalls.
- Type of coverage. Corrugated sheets with zinc or aluminum coating are the cheapest, but do not resist corrosion well. More expensive brands coated with polymers (plastisol, polyester, pural) last much longer than usual.
- Size. The size of the sheet must correspond to the geometry and area of the slope. For large roofs, you can purchase corrugated sheeting, cut along the length of the slope, then during installation you will have fewer seams, which means the coating will be more reliable and durable.
- Load-bearing capacity. The more bearing capacity corrugated sheeting, the higher the profile waves. This indicator is important for regions with heavy snow load.
- Color. Manufacturers produce profiled sheets for roofing in a standard palette. The shade of the material can be matched to the wall decoration.
Experienced craftsmen say that when purchasing corrugated sheeting, you should carefully study the packaging of the material. According to the requirements of GOST 24045 94, it must reliably protect the material from mechanical damage, contain information about the markings and characteristics of the coating.

Corrugated sheets (profiled sheets) are among the modern building materials, which is gaining increasing popularity in our country. And this popularity is largely due to wide possibilities application of this material.
Corrugated sheet (corrugated sheet) is a corrugated steel sheet, the profile of which is designed in such a way that high strength and rigidity are combined with relatively low weight. In addition, the corrugated profile promotes directed water flow, which is important when using corrugated sheeting for roofing works. Corrugated sheeting is ideal for roofing. Made from galvanized steel, the material is not subject to corrosion and is not afraid of moisture. And for additional resistance to external influences corrugated sheeting can have a polymer coating, which also increases its aesthetic properties and makes it possible to use a wide range of colors.
Corrugated sheeting can be used for both inclined and flat roof. At the same time, the roof turns out to be quite light and does not create excessive loads on the supporting structures of the building. Therefore, corrugated sheeting can be used for roofing work on very large-scale objects - such as industrial buildings and multi-storey buildings. If we add the presence of a complete set of additional and fastening elements, various low tides And decorative strips- then corrugated sheeting really seems to be a very promising roofing and wall material.
In low-rise construction it competes with corrugated sheeting. These building materials have much in common, but there are also significant differences in both appearance, and in areas of application.
On the one hand, corrugated sheeting is easier to use than metal tiles, since the roof is made of large sheets can be installed faster. In addition, it is almost impossible to use metal tiles on a flat roof - for proper water drainage, a metal tile roof must have a significant slope.
At the same time, metal tiles allow for more diverse options for architectural and decorative solutions when designing a roof. The aesthetic side of things when working with metal tiles plays a much larger role than when working with corrugated sheets. Corrugated sheeting is primarily a functional material, while metal tiles are also decorative.
On the other hand, metal tiles are only suitable for roofing, while corrugated sheets are a much more versatile material.
The second most important area of application for corrugated sheets is wall cladding. Any corrugated sheeting is suitable for this purpose, but it is best to use wall material. Such corrugated sheeting has a slightly different profile than roofing sheeting, since the most important goal in this case is not the rational distribution of water flows, but the high strength of wall coverings and optimal mode heat exchange.
Most often, corrugated sheeting is used to cover the walls of industrial buildings - for example, factory floors, warehouses and hangars. In addition, corrugated sheeting is widely used in the construction of quickly erected objects - such as shopping centers, indoor markets, hypermarkets and entertainment venues. Office buildings can also be constructed using corrugated sheets for wall cladding.
In large-scale residential construction, corrugated sheeting is rarely used, but in construction country houses and cottages, and especially auxiliary structures (garages, outbuildings, sheds), it can compete with siding and other types of wall coverings.
Finally, the third area of using corrugated sheets is the creation of strong and reliable barriers. Recently, corrugated fences have become increasingly widespread.
Corrugated sheeting is one of the few materials with which you can make very powerful fence. Unlike metal mesh, comparable to corrugated sheeting in terms of installation speed, corrugated metal sheet protects the area surrounded by a fence not only from unauthorized entry, but also from prying eyes. At the same time, corrugated sheeting is lightweight, that is, it does not require excessively massive load-bearing structures.
To this we can add that the price of corrugated sheeting is low, therefore, during the construction of large projects, its use allows you to save significant money. In addition, due to the ease of installation, time is saved. After all, it is thanks to materials such as corrugated sheets that it has become possible construction prefabricated buildings, when the construction cycle takes not months and years, but a matter of weeks.
