Corrugated sheeting is a universal building material and is used in different areas: How roofing material for roofs, as fencing (fences, wickets, gates), as permanent formwork for monolithic floors, as well as for wall cladding. Thanks to the stiffening ribs, corrugated sheeting is able to withstand significant loads, which is why it can be found on roofs. Thin sheet steel is used for roofing. Based on their decorative and protective properties, corrugated sheeting can be divided into galvanized and colored, which is painted with polymer-based paint.
Basically, the corrugated sheet comes corrugated. This material is classified by profile width and height.
Types of corrugated sheets
In order not to make a mistake in choosing a material, you need to know its markings well, which consists of a set of symbols of letters and numbers:
- Letter N (carrier) first means that the profiled sheet is stable and durable. It has the thickest metal with a high wave. In such corrugated sheets, there is an additional groove in the middle of the wave for greater rigidity.
- Load-bearing wall profiled sheet is marked NS. It is intermediate between load-bearing and ordinary flooring. This is a cheaper, but less rigid material, which is used to sheathe monolithic floors, roofs, fences, walls, awnings and gates.
- Wall profiled sheet has the designation WITH. It is made of thin steel and looks attractive. The width and height of its waves are small.
- Is there some more metal-polymer corrugated sheeting with markings MP. It looks like a wavy polycarbonate profiled sheet. This material is most suitable for roofs with attics. The protective polymer coating is not scratched.
In addition to letters, the marking also contains numbers. The first numbers indicate the wave height, the next ones, separated by a dash, indicate the width of the steel, and these are followed by the sheet dimensions.
Common brands of corrugated sheets
Corrugated sheeting comes in the following brands:
- Wall sheet C8- Used for wall cladding (for example construction trailers). For roofs it is used only with the use of continuous sheathing.
- More durable material C10. It is used for walls, fences, roofing (on a continuous sheathing).
- Wall profiled sheet C18 can be used for walls and roofs. Its ribs are strong and narrow, and its base is wide. It is coated with preservative polymers.
- Hard wall material C21 is uniform over the entire area and is used for fences, roofs and walls.
- Super strong C44 is rarely used for fences and walls due to its expensive price and high waves.
- A load-bearing profiled sheet with an additional rigid rib H57 is needed for roofing or monolithic floors.
- Universal corrugated sheeting NS35 is necessary for everything where the strength of the material is required: for walls, formwork, fences and roofs. It is also expensive.
- The more rigid NS44 is suitable for concrete monolithic floors and large roofs.
- Super-rigid H60 is used for the roofs of huge warehouses and workshops, as well as for the preparation of permanent formwork.
- The strongest of all, the H75 will withstand powerful loads. It has a high wave, thick material, and an additional hard rib. It is used for the construction of fences for luxury cottages. It is also the most expensive among all types of flooring.
The corrugated sheet is always covered protective layer. The simplest according to this characteristic is considered to be galvanized profiled sheet. This is followed by a zinc coating with additional silicon and aluminum. At the top there will be a corrugated sheet with polyester-based paint, then a Teflon-polyester coating, then a polyvinyl chloride coating with various additives. And finally, the safest and most reliable is PFDF corrugated sheeting. This coating protects for a long time from all kinds of atmospheric factors.
Cladding steel sheets have always been distinguished and valued for their attractiveness, durability and reliability. The iron bent corrugated sheet goes through priming, galvanizing and passaging. The ribs on it are formed by rolling through special equipment. And safe coatings make corrugated sheets truly eternal.
One of the most popular sheet materials on the market is corrugated board. Excellent performance characteristics coupled with low cost and versatility make this material optimal choice for most situations. Perhaps the only drawback inherent in corrugated sheeting is the difficulty of choosing the appropriate material for the solution. specific task. What kind of corrugated roofing there is, and the intricacies of its choice will be discussed in this article.
Advantages of corrugated roofing
The considerable popularity of profiled sheets is due to an extensive list of advantages, including:
- Long service life;
- Reasonable cost;
- Light weight;
- Practicality and versatility, allowing the use of corrugated sheets in the most different designs;
- Easy installation;
- Rigidity of connection with supporting elements;
- Resistance to natural and mechanical stress;
- Possibility to choose a suitable color.
The described qualities allow the use of corrugated roofing sheets both in private construction and in industrial facilities. This material can be used to arrange roofing structures any configuration.
Steel profiled sheets are available in two variations - with and without coating. The strength of the material increases due to cold deformation, giving the sheets a certain profile shape. The characteristics of the profile are the indicator according to which the classification of profiled sheets is carried out.
Selection of roofing material according to the degree of rigidity and corrugation height
Selecting profiled sheets is a difficult task, but it seems so only at first glance. All you need is to stock up on knowledge about various types corrugated sheeting and parameters influencing the choice of material. Proper selection will allow you to create the most reliable and high-quality construction, capable of serving for many years.
The height of the wave directly affects the durability of the entire structure. Of course, with a high wave height, the strength of the sheet itself increases, but this factor also has back side– water flowing along the bends puts pressure on the attachment points of the corrugated sheets. As a result, this leads to an increased risk of leaks in the screw holes.
However, sheets with a low wave height are still not suitable for roofing - their rigidity will not be enough for normal use. Minimum fin height sheet metal for the roof – 20 mm. Of course, this condition does not apply to regions where precipitation is extremely rare and insignificant - in this case, you can even install a completely flat roof. However, in our country there are no regions with such a climate.
From all this we can draw a simple conclusion - the best option profiled sheets for roofs are products with high ribs and a large number of them per meter, since this is the material that has sufficient rigidity. Among the specific options, we can immediately highlight corrugated sheets of grades N-60, N-75, N-114, N-153 and N-158, which meet the specified requirements.
Marking and types of stamped floorings
Modern corrugated sheeting is divided into several types, which are designated as follows:
- N – load-bearing profiled sheets, optimally suited for the installation of flat roofing structures and ceilings;
- C – wall sheets that have minimal strength and are therefore used only for finishing walls and fences;
- NS are universal products, suitable for both flat and flat surfaces. pitched roofs;
- MP are specialized roofing sheets developed by the Metal Profile company.
Products with the following markings are best suited for roof installation:
- S20K thickness 0.4-0.7 mm;
- NS35 thickness 0.55-0.8 mm;
- NS44 thickness 0.6-0.9 mm;
- H57 thickness 0.6-0.9 mm;
- H60 thickness 0.6-0.9 mm;
- H75 thickness 0.6-0.9 mm;
- H114 thickness 0.7-0.9 mm;
- All profiled sheets are marked MP.
All types of corrugated roofing are worth considering in more detail.
Profile S-20
Profiled roofing sheet brand C20 has trapezoidal corrugations, due to which the basic strength of the product increases. This type of coating is very unpretentious and does not require maintenance - all dirt is washed off from the sheets when it rains. It is also worth noting the large assortment of coatings and the widest range of color scheme, so choosing the optimal option from a design point of view will not be difficult.
C20 sheets are easy to cut and easy to install. If necessary, they can be removed and used again. High strength allows the material to withstand severe loads, to the point that corrugated sheets of this brand are often used as load-bearing materials.
In addition to the advantages already described, it is worth noting the low cost compared to analogues.
Profiled sheet C21
Having the same advantages as the previous version, the profiled sheet for roofing grade C21 differs even more greater strength. Such sheets are quite practical, which allows them to be used not only as roofing material, but also as cladding for walls and fences.
It is also worth noting a separate stamp for roofing - a subtype of the S20K brand. Its difference lies in the presence of a special groove that drains water from the roof.
Profiled sheet NS35
NS35 grade sheets are used primarily for roofing. A unique feature of the material is a 35 mm high rib made in the shape of a trapezoid. The letter H in the marking indicates that such products can be used as carriers. Profiled sheet NS35 is available with any type of polymer coating.
Sheets of this brand, produced by cold profiling, have excellent performance characteristics and are quite economical. Despite light weight, this material perfectly withstands various weather conditions and heavy loads. One of unique qualities NS35 sheets have a small windage, which allows them to be used in regions where there are often strong gusty winds.
Among other things, such sheets are very convenient to process and easy to install. The corrugated sheet installed on the roof will not cause any complaints throughout the entire period of operation (of course, if the region is characterized by a normal climate).
Profiled sheet NS44
Profiled sheets of this brand are even more durable than the previous version. Such high characteristics allow NS44 sheets to withstand even hail, not to mention temperature changes.
Like all the brands described above, it is not advisable to use these sheets in very snowy areas - but for all other situations such material will come in handy.
Profiled sheet NS57
If it is necessary to arrange a roof in the northern region with a significant level of snow precipitation, it is worth using profiled sheets of the NS57 brand. Even with a large distance between the rafters (up to 3 meters), this material can withstand very heavy loads.
Sheets of this brand are actively used in the installation of roofs for hangars, warehouses and roofs. residential buildings in snowy regions. This material easily resists any atmospheric loads.
Profile H60
Profile sheets of grade H60 are most often used for arranging pitched roofing structures. With a sheet thickness ranging from 0.5-0.9 mm, its weight is only 5-12 kg per square meter.
To produce H60 sheets, high-quality steel and a protective coating are used to prevent any impact on the roof. The strength of the material is so high that it can easily work for fifty years without any problems. Thanks to a special groove, which further increases the strength of the material, water does not linger on these sheets.
Profile H75
H75 profile sheets are used for installation of load-bearing and flat structures. With a thickness varying from 0.7 to 1 mm, the mass square meter material can be 9.25-12.9 kg.
Having ribs with a special bending shape, such sheets can withstand incredible loads, which is why they are used mainly for arranging industrial buildings and facilities. This corrugated sheet belongs to the load-bearing category, but it is often used when installing floors.
Profile H107
Sheets of the H107 brand differ from their analogues in their maximum strength, which allows them to be successfully used for the installation of pitched roofs. High strength indicators are determined not only by the large thickness, but also by the high rib coupled with the trapezoidal profile shape. As a rule, such sheets are used in private construction to create the most reliable and unpretentious roof.
Profile H135
Profiled sheets of this brand are designed for use in the construction of inversion roofs. Speech in in this case goes about maximum loads– on such a roof you can safely arrange summer areas with high traffic and even small parking lots. In private construction, the H135 profile is used to create sports fields or gazebos on roofs.
Profile H158
Finally, the most durable material in the presented line is the H158 profile. It is optimally suited for structures with low weight and large bearing capacity. If necessary, this type of corrugated sheeting can be used in roofs with spans up to 9 meters long.
This material is practically not used in domestic construction - it is quite expensive, and such investments will not be justified. It is best to consider all types roofing sheet and select those that are optimally suited for work in specific conditions.
What kind of coverage is there?
In principle, a corrugated roofing sheet can be made of ordinary sheet steel without any coating - but its characteristics will be seriously reduced because of this. In order for the roof to serve for a long time and reliably, it is worth paying maximum attention to the coating of the sheets.
Corrugated sheeting can have the following types of coatings:
- Polyester for increased structural strength and prevents loss decorative properties;
- Polyurethane, which protects the material from exposure to negative temperatures;
- Polyvinylidene fluoride;
- Plastisol, visually imitating wood or leather, provides protection from most external influences;
- Zinc, practically free useful properties;
- Aluzinc, which protects the roof from scratches and paint fading during operation;
- Matte polyester, which increases the wear resistance of the material;
- Pural, which protects corrugated sheets from fading and loss of performance characteristics;
- PVDF (polyvinyl difluoride acrylic paint), which protects the structure from chemical influences and ultraviolet rays.
To figure out what coating was used in a particular case, you need to pay attention to the markings:
- A – profile sheets are coated with a layer of aluminum;
- AK – sheets are treated with an aluminum-silicon layer;
- AC – aluminum-zinc coating (aluminum content is only 4%, so the increase in performance is insignificant);
- EOTS - the sheet was coated with protection on both sides through hot processing.
It is worth paying attention to these characteristics of roofing corrugated sheeting - the material used as a roofing covering is regularly subjected to serious loads.
Quality of profile sheets
Finally, in order to truly choose better quality sheets, you need to evaluate the following indicators:
- Sheet thickness. As practice shows, it is not worth purchasing the thinnest sheets - they are very often counterfeited. It is difficult to check the authenticity of a sheet, but it is worth knowing that sheets with a total thickness of about 1.15 mm, taking into account the coating, are used for roofing. To avoid purchasing a fake, you should contact a specialized store.
- Raw material quality. Manufacturers often skimp on raw materials, but the result is material of insufficient quality. In order not to make a mistake with your choice, you should, firstly, not look for sheets at dubious points of sale, and secondly, always look at the quality certificate attached to the material.
- Inner side of the sheet. Need to inspect before purchasing inner surface corrugated sheets for color uniformity. High-quality material has no streaks or stains.
- Package. Quality materials are always in high quality packaging. Sheets placed on regular pallets and wrapped in thin film are clearly not worth buying.
- Correspondence individual requirements . When selecting sheets, you must first take into account the requirements imposed by specific conditions. There is no need to buy the first sheets you see just because the seller thoroughly praised them.
Conclusion
The choice of corrugated sheets must be approached wisely, carefully studying all the necessary aspects. Incorrect choice may cause premature damage to the roof, but good material will last long enough and will not cause problems.
Corrugated steel sheets have been and remain popular due to their performance characteristics. Lightweight, durable, easy to install, the material is widely used in interior decoration, in the construction of light structures and as a roofing material.
Today, the position of sheet steel in construction has significantly strengthened. Corrugated sheeting is a modern material with a protective coating. Steel sheets are profiled, due to which they have big amount positive qualities, including aesthetic ones.
Structure of corrugated sheets
What is corrugated sheeting? This is a sheet of steel (cold rolled) with a protective layer applied. Polymers, zinc or aluminum, or alloys of zinc and aluminum can be used as coatings. Their profile, initially flat sheets, is obtained thanks to forming shafts industrial machine. This ribbing makes the sheets more rigid and durable. The profile can be of two types: trapezoidal or wave-shaped.
Important: wave height determines quality corrugated sheets, the higher, the better quality. Minimum profile height 8 mm, maximum 75 mm.
What is corrugated roofing? The width of standard sheets ranges from 1130 to 1200 mm, the length is custom-made (from 300 to 12000). Sheet thickness 0.4 -1.2 mm. Thin corrugated sheeting is used for cladding premises; thick sheeting can be used in the construction of small structures and in the roofing sector.
Modern profiled sheets are coated with a polymer, in most cases polyester (a polyester substance) is used. This coating provides higher strength and provides decorative function(10 year warranty). In addition to polyester, the following compositions can be used:
Pural – PUR marking, increases resistance to mechanical wear;
Polyvinyl dente fluoride – PVDF marking, will protect the coating from exposure to ultraviolet radiation.
Polyvinyl chloride - PVC marking, protects steel sheets from corrosion.
Acrylic - AC marking.
Important: large manufacturers of corrugated sheets practice the creation of complex polymer protective coatings. The compositions of the mixtures are a trade secret of enterprises. Using these coatings, manufacturers produce different types of corrugated sheets (matte sheets, coatings with colored patterns or designs).
Types of corrugated sheeting and areas of its application
Today, several types of corrugated sheets are produced, divided by areas of application:
Wall - load-bearing sheet. According to its characteristics, this type of coating is considered universal. The profile has increased strength, can be used for the construction of internal partitions or wall cladding. Marked with NS.
Roofing sheeting. Marked with the letter N, used as an independent roof covering. It has the highest strength indicators, therefore it is widely used in the construction of non-residential premises (hangars, garages, etc.), and is often used for the construction of fences and entrance gates;
Wall profile, marked C, is used for wall cladding, construction of partitions, fences, gates.
Important: all types of corrugated sheets are popular today, but one of the most popular is wall sheet C-8. The wave thickness of 8 mm is universal; this type of coating is suitable for almost all types of work.
More detailed description The types of material are shown in the photo below:
Pros and cons of the material
The main advantages of profiled sheets:
The manufacturing material does not corrode even after long-term use.
Easy to install.
Long service life over 50 years.
High strength.
Resistant to fire and leaks.
The material is not difficult to care for.
Affordable price.
Wide palette of colors.
Despite such significant advantages, corrugated sheeting also has a number of disadvantages. Among which:
Significant noise level. Steel sheets will not hide the sound of rain.
Heating the coating in the sun.
Important: these disadvantages can be minimized with proper installation. To reduce noise, it is recommended to lay soundproofing material under the bottom of the roofing corrugated sheeting; a well-assembled roofing “pie” will protect from overheating.
Installation features
Corrugated sheeting, like any other steel material, requires high-quality fasteners. The slightest defects will be visible not only on the fence, but also on 
roof. For everything to look aesthetically pleasing, the fastenings must completely match the color of the corrugated sheets themselves.
Important: painting is needed not only for beauty; painted screws are protected from harmful effects precipitation, which means they will last longer.
High-quality self-tapping screws must be tightly connected to the sheet - the rubber gasket is securely and elastically fixed to the corrugated sheet. On average, 6-8 pieces of self-tapping screws are needed to fasten one sheet when installing a roof. It must be taken into account that the places at the end of the roof must be further strengthened by reducing the fastening pitch to 500 mm.
When installing the fence, the sheets are fastened to the pipe using self-tapping screws with a rubberized washer. To fasten one sheet you need 5-8 self-tapping washers.

Profiled sheet is a building material that is manufactured in the form of individual metal sheets, which are specifically designed to cover any premises in order to protect them from precipitation, wind and other external factors.
This material is made from galvanized steel, using the cold profiling method, after which the surface of the sheets takes on a wavy shape.
The professional sheet is one of the highest quality and durable materials and therefore the demand for its acquisition and use in the process of construction of structures is gradually growing.
Profiled sheets are tougher, more durable, and their range is much larger.
Corrugated sheeting is characterized high degree sound absorption, but when finishing the roof with corrugated sheets, you need to additionally use soundproofing materials. Also, due to the fact that corrugated sheeting is a rigid structure with complex terrain, this allows it to be used during installation at any height, and it can withstand heavy loads.
In fact, corrugated sheets and corrugated sheets are the same material, only corrugated sheets are most often called roofing materials, and corrugated sheets are a universal covering.
Advantages and disadvantages
Advantages of the material:
- Profiled sheet has significant stability when exposed to corrosion, ultraviolet radiation and precipitation.
- Thanks to the presence of sliding properties, snow or dirt does not remain on the roof, but immediately flows off it.
- The long shelf life of the material is about 50 years.
- Installation of the coating can be done easily and without problems, not having great experience in construction.
- Versatility in application.
- Nice appearance.
- Environmental friendliness and safety of the profiled sheet. At high temperatures toxic compounds are not released.
- Light weight simplifies the process of transporting corrugated sheets to site construction work.
- Affordable price for the purchase of profiled sheets allows you to purchase it at average costs.
- Provides reliability and leakage protection.
Disadvantages of a professional sheet:
- Material in sunny weather gets very hot.
- Poor sound insulation— pronounced sound from precipitation hitting the roof.
- If the installation of construction work is carried out unprofessionally, then The roof seal may be compromised.
As you can see, the disadvantages are in the minority, and this allows us to talk about the versatility, high practicality and functionality of the material.
Types of corrugated sheets for roofing and choosing the best
The load-bearing type is intended for creating partitions and finishing walls. 
It can be bought for a small price, and also issued individual order when you need sheets of a certain size.
With its help, you can not only construct some elements of the building, but also easily repair the roof, finish the facade, its walls, ceiling, and even build durable fences.
When calculated per square meter, this material has low weight and good strength.
The wall profiled sheet has a rectangular or trapezoidal profile with polymer coating or it can be galvanized. If you make walls from it, they will be much lighter in weight than buildings made of reinforced concrete. Wall corrugated sheets are convenient and easy to cut if you need to make façade cladding or facing works
, installation of load-bearing elements, as well as production of decorative metal structures. Which corrugated sheet is better for the roof of a house? Roofing profiled sheets (series N) are used for the construction of roofs and any fences
that can withstand bad weather. It can withstand heavy loads.

Coating features S – wall, N – load-bearing).
NOTE!
The durability and strength of the entire structure is ensured by the fact that the profiled sheets have 8 protective layers.
Due to the fact that high-quality profiled sheets are covered with varnish coating(polyester, polyvinyl chloride), they look aesthetically pleasing. Their shelf life also increases.
The material has many positive properties:
- fluorescent;
- heat resistant;
- anti-corrosion;
The material can easily withstand any external influences and is environmentally friendly.
Marking
Where can corrugated sheets be used?
- During the construction of fences, both permanent and temporary, for the purpose of carrying out repair work.
- To create parking lots and parking lots for cars or sheds at places of sale of products.
- When permanent formwork is made during the construction process.
- To make sandwich panels using a special European technology arrangement of wall coverings.
Profiled sheets are used as insulation for facades of various types of premises:
- industrial;
- residential;
- commercial;
- for making roofs on roofs of various buildings.
If you need to make floors in buildings, ceiling and wall partitions are created from corrugated sheets.

Most popular markings
Today there is a large number of materials from profiled sheets and, as a rule, only some of them are most actively used, which are much better and easier to use. The most popular markings of profiled sheets include:
- C8. This marking of profiled sheets is most often used For decorative covering walls. The performance characteristics of this brand have much in common with C10 sheets, which are ideal for building high fences the dimensions of which reach more than 250 cm.
- H57. Profiled sheets are rigid and suitable for erect various fences and have an attractive appearance.
- H75. Profiled sheets of this brand suitable for absolutely any type of construction work and are stable if they are used to make fences in the form of walls.
- S21. Corrugated sheet materials can be used For roofing works, construction of fencing and wall cladding.
- C18. Profiled sheets are produced in the form of conventional galvanized products and cover them with all sorts of polymer materials. They are intended for installation of roofs on pitched roofs and panel fences.
- NS44. This brand can be used for any construction and installation work.
Roofing from corrugated sheets: calculation of the number of sheets
To calculate the material for the roof, you will definitely need information about the dimensions of the material used and the roof. To start It is recommended to start with the calculation rafter system.
You also definitely need information about your expected weight. finished design, and the cross-sectional values of the beams taking into account the coating material.
The main components of the rafter system are logs and beams, which are intended for the construction of a roof frame. done after calculating the load on the roof, which takes into account the weight of the roof, its covering and its own weight.
This is done to provide for all possible loads on the roof. In addition, the calculation of the load includes the weight of the workers who will be handling it and strong gusts of wind.
Attention!
To calculate the coating and rafter system, use our! After calculating the total load, the quantity is calculated wooden beams, which are distributed in a certain direction at angles.
Calculations:
- In order to determine what load will be optimal for linear meter parts of the rafter system, you need to use tables with detailed calculations that are found in the specialized literature on construction.
- The total footage is calculated.
- The total number of beams is calculated by measuring the length of one of them.
Roofing pie
—this is a structure consisting of several layers, which is made to create a roof. It consists of: sheathing and counter-lattice, and. The only thing that is not included is the rafter system.
Installation roofing pie done this way:
- Take the counter-lattice and install it on the surface of the rafter system. It can be attached between the beams if the roof is made of corrugated sheets, gable, hip or multi-gable.
- Waterproofing materials are placed on the insulation.
- For the profile sheet, you need to install the lathing, taking into account the gaps for ventilation.
- Roofing profiled sheets are laid out.
Roofing pie
The use of profiled sheets is quite diverse and provides long term services. Thanks to this material, it is possible to make both individual structures in the form of fences and install the roofing pie. Unlike corrugated sheeting, it has many advantages that make it indispensable in the construction process.
