Metal profiles for roofs are used when installing roofs on objects for various purposes. It can be seen on:
Depending on the price and size, roofing sheets are also used for installation and wall finishing.
Regardless of how much a profiled sheet costs, it is in steady demand. This is explained by its undeniable advantages:
The disadvantages include:
Corrugated sheets are used for roofing different types. The most popular ones include:
Corrugated sheeting varies according to the type of protective coating. It could be:
When choosing roofing corrugated sheets, you should focus on its dimensions. Manufacturing companies offer material with various geometric parameters. We invite you to get acquainted with standard sizes to make it easier for you to select the sheets you need.
For the manufacture of corrugated sheets, rolled sheets with a width of 1250 mm are used. The final dimensions of the profiled sheet for the roof, its length and width, depend on the configuration and height of the profile being formed and the requirements for the geometric parameters of the material. Thus, C8 has a useful width of 1.15 m with a total width of 1.2 m, and NS35 - 1 m and 1.06 m, respectively.
The length of finished sheets can reach 14 m. Due to increased transport costs, such material is not purchased, giving preference to sheets 2 m, 3 m or 6 m long.
Manufacturers offer corrugated roofing sheeting in various thicknesses. For production, metal sheets with a thickness of 0.45 - 1.2 mm are used.
Attention! The greater the thickness, the longer the corrugated sheet will last and the more reliable it will be in operation.
When deciding what thickness to choose a corrugated sheet for a roof, you should take into account that thicker material has more high cost and weight. In the first case, the cost of finishing the roof increases, and in the second, the load on the supporting structures increases.
Attention! You should not purchase corrugated sheets for roofing that are thicker than specified in project documentation: This may negatively affect the performance of the rafter system.
The configuration of corrugated sheeting offered by manufacturers depends on its type. The height of the corrugation is usually 35 – 44 mm. Compared to wall sheeting, galvanized corrugated roof sheeting has a higher profile to ensure timely installation.
In addition to the profiled roof sheet itself, it is necessary to purchase a number of additional elements, the price and size of which do not depend on the parameters of the sheet. To work you will need:
To do right choice, you need to clearly understand why and what kind of corrugated roofing you should choose. When purchasing, you should pay attention to:
When choosing a suitable brand, you should also take into account the opinions of real consumers:

corrugated sheet C21
Before starting installation work, you should purchase a sufficient amount of roofing material. To do this, we first calculate the required number of sheets in the following sequence:
One of the most popular building materials is a professional sheet. It is quite practical, inexpensive, and climate resistant. It is used both individually and in industrial construction. In order to profile a steel sheet, it is subjected to the cold deformation method. There are different brands of it, which are mainly designated depending on its geometric dimensions.
It is a roofing material that must be galvanized using the cold pressing method. The initially smooth sheet takes on a wavy shape due to the impact of the press on it. As a result, stiffening ribs appear on it, which help to increase the mechanical strength and rigidity of this material. To protect the metal profile from corrosion, apply special paint or polymer coatings.
The main standardization document for the material in question is GOST 24045–2010.
Let's consider what kind of corrugated sheeting there is.
Depending on the performance characteristics and areas of use distinguish it into the following categories:
In addition, corrugated sheeting is divided according to its coating into the following types:
All manufacturers take into account certain geometric parameters of the corrugated sheet during the production process.
The standard size of the profiled sheet is: height - up to 2 m, length - 2/3/6 m.
She reflects geometric dimensions of this material, as well as its type. Currently, manufacturers produce the following types: H, C, HC, MP.
The first three designations show the classification unit of the profile according to the first classification criterion: N - load-bearing, C - wall, NS - universal. MP is a metal polymer that serves as a roofing material over the attic.
The first number following the letter shows the height of the sheet (mm), the next - the thickness of the steel that serves as the basis for stamping the sheet (mm), the next - the width of the sheet (mm), the last - the maximum length (mm).
On profiled sheets with an aluminum-zinc coating, the letter designation AC is added to the marking.
There is also a profiled sheet produced by cold deformation using a radial machine. In this case, the letter “P” is present in its brand.
The most common is P20 grade corrugated sheet. It has a working width of 1150 mm, a metal thickness of 0.4 to 0.8 mm, and a profile width of 67.5 mm. It is characterized by high anti-corrosion resistance, high mechanical strength and light weight.
The material has the following characteristics:

Corrugated sheets are called corrugated (profiled) sheets of galvanized steel. This material very widely used in construction. It is excellent for wall cladding, roofing, construction of panel fences and frame structures. And this is only a small part of the work where corrugated sheeting can be used - the dimensions of the material allow you to choose the optimal value for any conditions.
There are several main areas of use of corrugated sheets:
Wall corrugated sheeting has dimensions such that it can be easily installed on a wall or on supports to create a fence. The wave height of the corrugated sheet is small, and the steel base is also the smallest compared to other types of material. In view of this, wall corrugated sheeting is used where the load on the surface will be small - in barriers, wall partitions, suspended ceilings. In construction industrial facilities wall corrugated sheeting is used for finishing vertical surfaces and walls. Due to its low height, the material is highly economical. It is very important that the metal profile can be used several times.
The group of wall profiled sheets includes the following brands:
Roofing corrugated sheets are distinguished by a higher profile sheet height - 20 mm or more. The dimensions of corrugated roofing may vary depending on the needs of a particular construction. Due to the presence of additional stiffening ribs, this type of material has greater strength. Roofing corrugated sheeting is used for arranging roofs, structures, hangars, fences, pavilions and stationary fences. This type includes brands C44 and NS35.
The greatest strength is inherent in the load-bearing profiled sheet. It is made from steel sheet of the greatest thickness. The profile height (corrugation) starts from 44 mm. Thanks to these factors, the load-bearing profiled sheet can withstand heavy loads. Therefore, it is used for arranging permanent formwork and floors. This group includes brands H60, H75, H114.
Profiled sheet C8 has following parameters:
This type of material is one of the most economical. Its popularity is explained at an affordable price and excellent performance characteristics (more details: " "). The advantages of C8 grade profiled sheet include reliability, durability and ease of installation.
TO distinctive features The brand can be attributed to the low profile height and incredibly convenient sheet width. C8 is used for the construction of temporary structures and installation of fences. This type of corrugated sheeting is also used for wall cladding and suspended ceilings.
Due to its low weight, the profiled sheet can be used for mounting structures on top of light frames (more details: " "). This contributes to an overall reduction in installation costs. The low profile height helps to minimize space loss, which becomes especially important when interior decoration walls and surfaces. Well, these sheets are not particularly difficult.
But it should be understood that C8 corrugated sheeting cannot be used to cover the roof (read also: ""). Low rigidity will not allow this material to effectively withstand loads. Only temporary roof covering is allowed during repair work. And yet, the main area of use of C8 corrugated sheets is the creation of fences.
The profile of sheet C21 has a trapezoidal shape. Standard parameters The lengths for this brand of corrugated sheeting are considered to be 2, 3 and 6 meters, which is what it is designed for.
Corrugated roofing dimensions:
Profiled sheets of this brand are used in the following areas:
Roofing corrugated sheeting has the following parameters:
This one has additional stiffening ribs. If we also take into account the fact that the thickness of corrugated roofing C44 is much greater than other types of roofing, then it becomes immediately clear that this brand is intended for creating structures that must withstand significant static and mechanical loads.
Most often, C44 corrugated sheeting is used for:
This corrugated sheet has the following dimensions:
Roofing corrugated sheets have occupied the leading positions in the building materials market for many years. Unique properties and practicality allow it to be used in the most different conditions, and the price pleases with its availability.
That's just how to choose a suitable profiled sheet for a roof with a certain angle of inclination and operational features? What should the height of the corrugation be, are special grooves needed and what coating should be preferred? We will now answer these questions for you.
First, let's answer the question why corrugated sheeting is so popular among others roofing materials. All because of such valuable qualities:
Modern profiled sheets cover both industrial and industrial buildings huge area, and residential buildings with the most different types roofs - flat, semicircular, stepped and complex shapes.
And the profiled sheet is made of steel, with or without coating. For additional strength, profiled sheets are cold bent to form a specific profile. And depending on how the ribs were made, what height, frequency and shape they are, it depends on whether this or that type of corrugated sheet is suitable.
So which corrugated sheet is more suitable for roofing? We suggest you look into this issue in more detail, because... experienced builders, for example, we are sure that even the most ordinary profiled sheet correct installation will serve faithfully for a long time. But you want durability and ease of maintenance, right?
It is a well-known fact that the higher the wave, the stronger the sheet, and the less likely it is for water to overflow over the wave. What does this give? The fact is that such “waves on rocks,” when water flows into another bend, significantly enhance water pressure on the screw holes. Naturally, the risk of leaks in this case is much greater.
Sheets with a small profile height are least suitable for roofing as they are not rigid enough. To withstand the load of snow in winter and the weight of human feet during the repair process, the corrugated sheet for the roof must have an edge of at least 20 mm. Of course, if you are building a house in southern country, where there is almost no snow, almost any type of corrugated sheeting is suitable for you. Therefore, do not trust spectacular photographs of houses with almost flat corrugated sheets - there is no snow in such regions, otherwise it would bend the roof in the first snowfall. And this is not for Russian latitudes in any case.
So, the higher the ribs of the profiled sheet and the greater their number per meter, the stiffer the profile, and the more additional load it can take on. The most reliable in this regard are corrugated sheets of the N-60, N-75, N-114 brands and Europrofiles N-153, N-158.
Let's first look at the markings of modern profiled sheets:
So, what types of corrugated sheeting are suitable for the roof? Let's list them all:
And now about each in more detail.
The C20 profiled sheet has trapezoidal corrugations along its entire length, which provide additional rigidity and strength. This roof covering does not require special cleaning or maintenance - any dirt is easily washed off with regular rain. And C20 corrugated sheets are sold with almost any coating - from pural to granite, and almost any fashionable shade.
Easy to cut, easy to install on the roof and can even be reused. The minimum pitch of sheathing on the roof for such a covering is 0.4 m.
Due to the large margin of safety, such a roofing covering can withstand quite strong deforming effects. This profiled sheet is so durable that in some conditions it is even used as a load-bearing sheet.
The main advantage is, of course, the price.
Profiled sheet C21 is an even more durable material than its previous analogue. This type of corrugated sheeting is considered universal: suitable for roofing, walls, and fences.
An excellent subtype is the C20K corrugated sheet, which has an additional groove for water drainage.
This profiled sheet is classified as a roofing sheet. All because of its special strength, which has high level thanks to trapezoidal ribs with a height of 35 mm. And the fact that the sheet is also load-bearing is indicated by the letter H in the marking. The polymer coating can also be of any kind.
NS 35 profiled sheet is produced using the cold profiling method. The uniqueness of this type of corrugated sheet is its efficiency, which is combined with excellent performance. Excellent resistance to weather conditions, mechanical strength and at the same time relatively low weight. And what is most valuable, such a profiled sheet is best suited for regions where there is little snow, but there are strong winds. Thanks to little specific gravity tearing off such a roof is no longer easy - the windage is not the same.
It is also easy to cut and easy to install, and its strength allows it to be used on fairly flat roofs in regions with little snow. Under normal (not extreme) conditions, it does not deform or sag. Main scope of application: pitched, flat and semicircular roofs.
Looking for something durable, but at the same time flexible for cutting and mounting? Then this is the most suitable professional sheet.
This brand of corrugated sheeting is similar in all its parameters to NS35, only stronger. Excellent protection against hail, frost and extreme heat. Like NS 35, it can be used where strong winds, but not much snow.
Is the weather in your area unpredictable? Then this brand is right for you.
This is a high-strength profiled sheet designed for significant loads. The pitch of the rafters can be made quite wide and not worry about anything.
Today, the NS57 brand is more in demand for the roofing of hangars and warehouses, as well as roofs in fairly snowy regions. The special strength of such corrugated sheeting allows it to withstand severe wind loads. In addition, this profiled sheet is used for roofs with spans of up to 3 meters!
Is it just a stone's throw from Siberia? Then cover the roof with corrugated sheets, and you will be calm.
Profile N-60 is actively used for pitched roofing. Sheet thickness is from 0.5 to 0.9 mm, and weight is in the range of 5-12 kg per square meter.
Profiled sheet H60 is made from steel sufficiently High Quality, and covered with a protective layer from weather conditions. It is so durable that it can serve as a roofing covering for 50 years. And it can be used in regions with strong wind loads. It also has a special groove to enhance strength and drain water.
Profile N-75 is intended for arranging load-bearing structures, floors, pitched and flat roofs. It is already thicker - 0.7-1.0 mm, and its weight ranges from 9.25 to 12.9 kg per 1 m 2.
Thanks to specially curved ribs, H75 corrugated sheet is capable of withstanding enormous loads, and therefore is most in demand in the construction of industrial facilities. This is a purely load-bearing corrugated sheet, which is also actively used for floors.
Profile N-107 is the strongest among traditional load-bearing corrugated sheets and is 100% suitable for arranging a simple pitched roof. The profile of this brand is high and trapezoidal. The sheet thickness ranges from 0.7 to 1.0 mm, which is already quite a lot, and the weight ranges from 10.2 to 14.5 kg per 1 m 2.
Are you planning to build a house that will last forever so that your grandchildren can enjoy it too? Then cover the roof with this profile - nothing is scary for him!
The N-135 profile has great rigidity and is used for arranging flat inversion roofs- the kind on which they build summer cafe and even parking. Those., we're talking about about serious loads!
Are you going to flat roof Make a sports ground at home or in a bathhouse? Open gazebo with a barbecue? Then you need this profile - it is designed for just such loads.
The most durable corrugated sheeting is grade N-158. It has the highest corrugation, and it can be used to cover the roof even with a support spacing of 9 meters! Usually such a roof is done if the maximum possible load bearing capacity, but the weight of the entire structure should not be large.
This profile is, of course, the apogee of strength and endurance. Why not take one right away, even if you have the simplest one? pitched roof? But the price! This is simply an unjustified investment. And, instead of overpaying for excess strength and durability, invest these funds in purchasing a more suitable profile, but with a good, high-quality coating, which will protect it from any hail.
Modern corrugated roofing is made from galvanized sheet, which is more budget-friendly, or from metal with polymer coating, which is more expensive, but more durable and reliable.
The coating of the corrugated sheet is also of great importance, especially when it comes to roofing. Indeed, in addition to the zinc layer, for roofing sheet It is desirable to apply additional coloring, which also directly affects the individual qualities of the coating. Here is the classification:
Special markings will help you understand what exactly the sheet is covered with. For example:
If for ordinary corrugated sheeting there is no significant difference with what it is covered with, then for roofing it is a key indicator, because such corrugated sheeting is constantly exposed to external environment. Therefore, choose a roofing covering based on what protective layer was used.
And now about how not to purchase a profile 5 mm thick and get 3.5 mm, which will corrode in the first year. What is the problem? In fakes!
When choosing a quality profile, pay attention to the following points:
Good luck with your purchase and successful installation!
