Home improvement starts with the right materials. An excellent solution would be corrugated board. This material has such qualities as durability, reliability, strength and has an attractive price. Also, not the last factor is a fairly light mass of corrugated board. This article will describe in more detail the weight of 1 m2 of profiled sheet.
Profiled sheet features
A profiled sheet is made from. With the help of a special press, profiles of a trapezoid, wave or ridge are squeezed out on it. To improve the anti-corrosion qualities, it is treated with a layer of polymer or paintwork.
Basically, the corrugated board is intended for But also the corrugated board has found wide application for the installation of fences, sheds and other premises. It is also used as a material for covering walls.
Advantages of a profiled sheet
The professional flooring has a wide range of advantages. The main advantages of corrugated board:
- Light weight. On average, the weight of 1 m2 of profiled sheet varies between 7-9 kg. This greatly facilitates both transportation and construction work.
- Profile durability. The material perfectly tolerates temperature fluctuations, does not give in to rotting and fungus, and is resistant to corrosion.
- Material strength. Can withstand hefty loads due to its high bearing capacity.
- Ease of use. Installation can be performed without specialized equipment, and the standard sheet size allows you to cost-effectively cover the roof of any area.
- Variety of colors. It has many color solutions, which allows you to choose a color for every taste.
Varieties of profiled sheet and its weight
Profiled sheet is used for various types of construction. Therefore, each of them has a number of characteristics, thanks to which it is easy to choose the necessary corrugated board for any area of \u200b\u200buse.
There are bearing, wall and universal profiled sheets. They differ in both their dimensions and weight. Data on the dimensions of corrugated board can be found from its marking:
- The first letter indicates the scope. The letter "H" means carrier, the letter "C" - wall, and the letter combination "NS" - universal.
- The first number is the height of the corrugation in mm.
- The second number is the profiled sheet width in mm.
- The third digit is the thickness of the corrugated sheet in mm.
Depending on the brand, the steel profiled sheet has a different weight of 1 square meter. The smallest weight of one m2 of profiled sheet starts from 4 kg. The universal professional sheet usually has the highest mass - up to 21 kg per 1 m2.

Permissible deviations for the following parameters:
- length - 10 mm
- corrugation height - 1.5 mm
- profile width - 0.8 mm
- weight - 20-100 grams.
The most reliable is the profiled sheet, which has a mass of 1 m 2 and the mass of a running meter are almost the same.
In general, when choosing a profiled sheet, you need to know not only its parameters, but also its mass. Thus, a difference of 1 mm in sheet thickness can equal a difference in weight of over 15 kg. For example, the weight of 1 m2 of profiled sheet is 0.7can be from 6.5 kg to 9.8 kg.
Profiled sheet, otherwise called corrugated board, is widely used in the construction industry. There are many types of such products with different purposes. They differ in the type and size of the profile, external coating and other characteristics.
Consider the most popular type of profiled material - C8 corrugated board, the features of its production, as well as characteristics, standard sizes and scope.
Specifications and dimensions of C8 corrugated board
The sheet profile C8 has the form of a trapezoidal corrugated surface. The height of each corrugation is 8 mm, the base of the trapezoid corresponds to 62.5 mm. The distance between adjacent waves is 52.5 mm.
The schematic drawing shows the C8 profile with the main dimensions:
An important characteristic is not only the total width of the finished sheet, but also the width of its working (useful) part. It is equal to the total width of the product minus its overlap on adjacent sheets.
- With a total width of 1200 mm, the working area will be 1150 mm.
- The distance between adjacent corrugations (wave pitch) also plays a role, it is equal to 115 mm.
- The thickness of the C8 profile metal sheet varies from 0.4 mm to 0.6 mm.
- The length of the product is from 0.5 m to 12 m.
- Depending on the thickness of the sheet, the weight of 1 m 2 of the product is different, it can reach a maximum of 5.6 kg / m 2.
A distinctive feature of the C8 profile is the identity of the shape of the corrugation elements on both sides.
This product is of two types: galvanized and polymer-coated. It serves to protect the product and at the same time performs a decorative role. The coating can be applied on one or both sides of the sheet. By painting the profile surface give completely different color shades.
Products with a one-sided coating are intended mainly for roofing of light structures that are not subjected to heavy loads.
Production of corrugated board C8
C8 sheets are made from galvanized cold rolled steel grades 220 - 350 and 01, manufactured in accordance with the regulatory documents GOST 14918 and GOST 30246.
- GOST 14918 is extended to galvanized cold-rolled steel and contains requirements for its high-quality production.
- GOST 30246 is extended to rolled steel with a protective polymer coating, which is applied on automated metal painting lines. Painted steel in finished roll form is supplied for the manufacture of profiled products.
The thickness of rolled sheet metal is 0.5 - 07 mm.
With the help of cold rolling on special mills, the prepared rolled metal is given a characteristic profile shape.
The main elements of the production line are:
- drum device for automatic unwinding and feeding of rolled steel;
- shaping roller mill;
- guillotine for cutting sheets;
- sheet receiving device;
- control panel for the whole process.
The technology for manufacturing a profiled sheet is carried out in the following sequence:
- Coiled steel is placed in a drum unwinder, from where it is fed to the profile rolling line.
- By adjusting the rollers of the mill, a given product profile is created.
- After obtaining the desired profile and bringing it to the specified dimensions, the semi-finished sheet is fed to the point of cutting along the length of the product using guillotine shears.
- The cut sheets are fed into the receiving device, where they are stacked into bundles.
The profiled sheet C8 has the designation according to GOST 24045-94 "profiled sheet S-8-1150-0.5", which has the following interpretation:
- C - wall (appointment of the material);
- 8 - the height of the corrugation trapezoid;
- 1150 - working (useful) sheet width;
- 0.5 is the thickness of the original metal sheet.
Quality requirements and methods of its verification
In accordance with the current standard, the following requirements are imposed on the C8 profile sheet:
- the product can have a profile height spread from -1.0 to +1.0 mm;
- tolerances for sheet width + 8.0 mm, and for length + 10.0 mm;
- for a sheet having a length of less than 6.0 m, the curvature should not exceed 1.0 mm per meter of length, and for a sheet over 6.0 m, it should not exceed 1.5 mm;
- unevenness (waviness) in flat places should not be more than 1.5 mm, and on edge bends more than 3.0 mm;
- for profiled sheet C8 with a polymer outer layer, small dents are allowed on the outer surface of the polymer, which do not destroy the coating;
- the back side of the product with one-sided coating, as well as the surface of galvanized sheets, should not have damage that violates its integrity and degrades the quality of the entire product. Damage with a depth of not more than 0.5 mm and a diameter of less than 10 mm is allowed.
- There are no cracks or deep scratches on the surface of the product.
What is the difference between C8 and C20
Based on the marking, the C20 corrugated board differs from the C8 product, primarily in the height of the corrugations. It is 18 - 20 mm for this profile.
There are differences in other parameters as well. The total width corresponds to 1.15 m, useful - 1.10 m. The thickness of the profile is from 0.45 to 0.7 mm. Wave step - 137.5 mm.
Despite the fact that both materials are wall materials, C20 has a large bearing capacity due to high profile corrugations that act as stiffeners. This expands the possibilities of using the C20 product. In addition to being used for walls, C20 is successfully used in the installation of the roof of residential and industrial buildings. In addition, a deep profile chute is convenient for water flow.
Options for using C8 in construction
Due to the minimum size of the corrugation height, the C8-1150 product has a low load-bearing capacity. This professional sheet is not able to withstand significant static effects, so the main purpose of these products is wall cladding. They are used for the following purposes:
- for finishing the facades of various buildings: residential buildings, industrial and public buildings, cottages and country houses;
- for the manufacture of fences and enclosing structures in places where there is a low wind effect;
- in the production of sandwich panels;
- for the construction of small outbuildings: change houses, makeshift houses, toilet cabins, sheds and garage doors.
S8-1150 corrugated board can be used with caution when installing a roof. In this case, it is necessary to observe the condition: the slope of the roof should not exceed 40 - 45 degrees.
To increase the bearing capacity of this material when using it for roofing, it is necessary to build a reinforced frame from rafters and battens. In addition, it is desirable to use polymer-coated products for roofing. They are more resistant to corrosion and mechanical damage.
Price range in the building materials market
One of the essential characteristics of any material in the construction industry is its price. For C8 corrugated board, it is its advantage, because in comparison with other profile products it is quite low. The cost per square meter of this material in different regions of Russia and neighboring countries has a small spread.
The manufacturer of corrugated board has a significant impact on the cost. Promoted brands are more expensive than products produced by unknown firms. This is quite understandable, since they have proven themselves by manufacturing high-quality products that have been in operation for many years.
There is no doubt about the high quality of products of such brands as atalogue, fine, stone, lang and the like.
On the building materials market, you can find a C8 profile sheet made in China, Korea, and Ukraine. Large Russian manufacturers of rolled metal products have proven themselves well, supplying corrugated board at wholesale prices.
The price of C8 corrugated board, which has a polymer coating, is higher than the same product made of galvanized steel. It can vary by 20 - 30%.
The average price of 1 m 2 of galvanized sheet, depending on its thickness, can be from 190 to 300 rubles. The price of coated products can vary from 270 to 350 rubles. per square meter.
The spread of prices depends not only on the presence or absence of coverage, but also on the type of coverage. For example, the highest price of a product with a thickness of 0.5 mm with an expensive coating has a price of up to 500 rubles / m 2. This is almost 2 times higher than the price of a simple galvanized product.
In modern construction, innovative methods and new materials are widely used. The most demanded is the S8-1150 corrugated board.
Initially, it was planned to be used as a building envelope. However, it turned out to be so versatile that it began to be used for other purposes.
profiled sheet
Advantages of C8 corrugated board
This is a relatively new building material. Used in various areas of construction:
- for fencing the site;
- ceiling lining;
- ennobling the walls of a building or barn;
- production of auxiliary buildings in the country;
- use as a false ceiling;
- lining of gates and gates;
- use as a roofing material;
- for the manufacture of sandwich panels.
Available in painted and galvanized sheet.
Corrugated fence Technical characteristics of C8 corrugated board
The panels are produced by cold rolling from an endless steel sheet of standard thickness, which gives its advantages:
- Allows you to produce material of various lengths. The standard provides sizes from 0.5 m to 12 m. In this case, the cutting step is 0.5 m. Factories can also produce non-standard sheet sizes at the request of the customer.
- The thickness is chosen from the operating conditions. For the fence, 0.5 mm is sufficient, and for the roof it is necessary to use sheets of maximum thickness.
- Manufacturers produce galvanized profiled sheet or sheet with a polymer coating. It doubles the service life. Materials that have a galvanized surface last 10 years, and those with a coating last 20–25 years. The professional sheet is issued various color scale. The choice of shade can be made according to the RAL catalog.
- Depending on the thickness of the source material, the weight of the product ranges from 3.87 to 5.57 kg per square meter.
The production of corrugated board is a fully automated process. The line includes an unwinding device, a rolling mill, guillotine shears, and a receiving device.
It is enough for the staff to install the reel with sheet tape on the unwinder, load it into the rolling mill, set the size and control the quality of the line.
In this case, minor abrasions of the surface are allowed, which does not violate the integrity of the protective coating.
Sheets of galvanized material A slight crescent and corrugation are allowed along the edges of the sheet. However, these parameters are strictly regulated and must be within the established values. Any deviation from the norm should not impair the technical characteristics and dimensions.
Do not use C8 corrugated board in load-bearing structures. Due to the small height of the profile, it is not able to withstand heavy loads.
Product labeling
The name of the product C8-1150-0.5, according to GOST 24045-94, contains all the necessary information:
- The letter designation "C" - says that these are wall panels.
- The number "8" indicates the height of the profile, which corresponds to 8 mm.
- 1150 - working surface. The width of the sheet is 1200 mm, but given the overlap of one sheet with another, a usable area is obtained. The working width is a parameter that you need to know when calculating the amount of material needed.
- The last digit indicates the thickness of the steel. It can range from 0.45 to 0.8 mm.
- If there is nothing after specifying the thickness, then the product is made of galvanized steel.
- Further designation refers to the material and its paintwork. Thus, AD ML-1202 refers to aluminum-coated rolled products with a protective layer of ML-1202 enamel.
Specifications The main areas of use of C8 corrugated board
The versatility of the material leads to a wide range of applications. In private construction, it is used for the construction of utility rooms as sheds, sheds, showers, etc.
Organizations build workshops with wall insulation, cold storage facilities, garages located on the territory of the enterprise. To reduce the cost, galvanized corrugated board is used.
Having a small weight, during construction, you can significantly save on wall beams. Buildings are light and do not require strong foundations.
Fences are made of more expensive material, with a polymer coating. They protect the area well from penetration and have an attractive appearance.
There should not be large gusts of wind in the fenced area, because. such fences have a large windage. Otherwise, additional structural reinforcement measures should be provided.
If you use C8 grade corrugated board with a double-sided polymer coating, then the fence will have an attractive appearance on both sides.
To finish the ceilings, sheets painted with white polymer paint are used. The light weight of the panels allows the use of such brands of corrugated board as roofing material.
However, it must be remembered that it cannot be used on roofs with an inclination angle of less than 30°.. In this case, you can significantly save on materials. And this means that the truss system will be lighter and cost much less.
Garage from wall profiled sheet The polymer coating is not only durable, but also has an attractive appearance. The use of corrugated board is possible when facing the walls of buildings that have lost their original appearance. And also as temporary partitions in workshops or industrial premises for zoning instead of wall material. It can be used in the manufacture of sandwich panels. In this case, it provides an aesthetic appearance and serves as a fence.
C8 profiled sheet price
You can buy profile material at any hardware store or directly from the manufacturer.
The cost of a metal profile depends on the thickness of the galvanized steel from which it is cold-rolled. Also, the price is influenced by the quality and material of the coating.
Table 1. The cost of C8 profiled sheet of galvanized metal
Table 2. The cost of C8 profiled sheet, painted with polymer paints
These are the average prices in the market. It should be borne in mind that the price of a galvanized sheet may differ from a painted one by 20–150%, and in some cases up to 250%, depending on the paintwork. The difference between galvanized and profiled sheets covered with pural is two times with the same dimensions. And with a polyester coating, the difference is 30%.
Before starting work, provide yourself with the necessary tools and protective equipment:
- The edges of the panels are very sharp and it is easy to injure your hands with them. Therefore, it is necessary to work only with protective gloves.
- When installing a roof from corrugated board, it is necessary to prepare special skis to lift the material onto the roof. This will avoid damage to the panels from deflection. This is especially true with a length of more than 5 meters.
- It is better to use a solid crate. This will save in the future from unwanted deformations during operation.
- Customize to size should be special tools that do not leave notches. For example, reciprocating saws, discs, guillotine shears.
- It is forbidden to walk on the covered roof in hard shoes. Which will lead to profile deformation. It is recommended to make special flooring from boards.
- The material can be fastened with special bolts with painted heads and a silicone or rubber washer.
- When installing a roof or fence with the help of hired workers, draw up a contract, which indicates the warranty period and penalties. This work is guaranteed for three years. By agreement of the parties, it can be reduced, but not less than one year.
Often sellers sell substandard goods at reduced prices. In this case, require certificates, which indicate the technical characteristics of the profiled sheet. It differs in working dimensions, useful area, modified geometry, declared thickness, profile defects, etc.
Professional sheet C8 rightfully belongs to the popular brands, it is valued for its combination of lightness, strength, good corrosion protection and affordable cost. These products do not have self-supporting capabilities, but their rigidity is sufficient for wall cladding, erection of fences, partitions and other structures. Their performance depends on the thickness and quality of the metal used and the type of coating.
This variety is made by cold rolling and has the lowest profile height - within 8 mm. The range includes galvanized and painted sheet steel products with a total width of up to 1250 mm (useful - 1150, which corresponds to 9-10 corrugations), length from 0.5 to 12 m. Technical parameters are regulated by GOST 24045-2016, to the main ones taken into account when purchasing , installation and operation include:
- The thickness of the profiled sheet and the steel grade. This indicator depends on the integrity of the manufacturer, varies from 0.4 to 0.8 mm.
- Geometric accuracy and integrity of the protective coating. In the absence of requirements for metal in the areas of curvature and the assumption of the use of products with minor abrasions and defects, these products have strictly regulated deviations from dimensions, the limit in height does not exceed ±1 mm, in width - ±8, in length - ±10. The profile parameters are also strictly controlled - the maximum allowable waviness is 1.5 mm, the step must be uniform.
- Mass of 1 m2 and 1 p.m. They directly depend on the thickness, the minimum allowable ones are indicated in the tables of GOST 24045-2016. The average weight of C8-0.5 corrugated board is 5.42 kg.
- The optimal step for cutting is 50 mm (taking into account the standard distance between the waves of 52.2 mm).
- The level of galvanization (it is also the density of the sheet). The standard value is influenced by the type of coating and varies from 140 to 275 g/cm2, the higher this characteristic, the better. Products with galvanization less than 140 g/m2 will last no longer than a year.
- Degree of glitter, %.
- The maximum operating temperature without loss of useful properties and aesthetics is up to 120 ° C.
- Manufacturer's warranty.
Many builders evaluate quality by density or the degree of galvanization. Depending on the thickness of the protective layer and the proportion of zinc in it, three classes are distinguished, the first has a minimum resistance to corrosion, the second withstands medium impacts, the third is designed for operation in extreme conditions. Group 1 includes galvanized profiled sheet with a gray film with a thickness of 25 to 30 microns, applied in a hot way. It is impermeable to air and water, but due to poor abrasion resistance, its service life leaves much to be desired.
Technical characteristics of painted one- or two-sided varieties are regulated by GOST 30246-2016. The outer layer performs protective and decorative functions, the color palette corresponds to the RAL catalog. The level of galvanization in such grades reaches 40-60 microns, they have maximum resistance to precipitation and UV. The basis is different, the best results are observed with polyester, plastisol, pural and similar polymer coatings.
Scope and features of application
The letter "C" in the marking of the profile stands for "wall", taking into account the requirements of building codes, such rolled products cannot be used for the construction of load-bearing structures or as roofing. In practice, this limitation is often ignored; at low wind loads, C8 corrugated board is purchased to protect roofs with a slope of more than 30-40 °. Alternative options include installation to a continuous crate. The main area includes:
- Manufacture of non-flammable sandwich panels and similar sandwich structures.
- Sheathing of the facade, internal and external walls, including insulated. The demand is explained both by the affordable price and the minimum load on the supports and foundations.
- Erection of fences, temporary buildings, garages, hangars, production and storage facilities, sheds, kiosks.
- Laying of shield structures.
- Upholstery of chimneys, increased fire safety in workshops.
- Assembly of ventilation shafts.
The scope of application is directly determined by the quality of corrosion protection. Polymer-coated profiled sheets are characterized by increased resistance to moisture, ultraviolet radiation and are many times more decorative in comparison with conventional brands. They are recommended to buy for decoration, the maximum effect is achieved when using panels that imitate natural wood, stone, brick. This group, in turn, is divided into elements with a one- and two-sided layer, the former are represented by a wider range of colors, the latter are valued for their equally attractive appearance on both sides.
Plain galvanized corrugated decking is ideal for building temporary structures, from site fencing to sheds and portable garages. With low or no requirements for aesthetics, it is allowed to use substandard sheets with minor deviations in size or other defects. If necessary, the service life can be extended with a simple staining, but these measures are taken at the initial stages of operation.
The profiled sheet is most often installed vertically, the presence of a crate or supports is a prerequisite for its installation technology. This material is not recommended to be cut using angle grinders, with the exception of circular saws. Ignoring this point leads to the formation of burnt spots on the zinc coating. C-8 is fastened or connected to each other using metal screws or rivets, the head of the screws is not completely tightened. This variety is easy to bend, but this is not recommended. The restrictions also include construction in areas with high vibration.
The calculation of the required amount of C8 corrugated board is carried out taking into account its useful width and the size of the overlaps. Depending on the type of construction, it is purchased with a 5-15% margin. Dimensions and performance are checked for conformity with markings and accompanying documentation. The color is chosen in advance, it must be combined with other finishing materials and the surrounding landscape. With low requirements for aesthetics and a limited budget, ordinary galvanized gray grades are sufficient, if necessary, they can be painted afterwards.
The focus is on the integrity of the anti-corrosion coating and the absence of obvious defects. The maximum allowable diameter of dents is 10 mm, their number per 1 m2 should not exceed 2, the same applies to deep scratches. Possible substandard include stratified and strongly curved edges. For unpainted galvanized grades, white stains on the surface serve as a sign of marriage.
In addition to visual inspection, it is worth checking that the declared thickness and weight correspond to the standard value. A downward deviation indicates a poor quality of rolled products, the material will not withstand the expected loads. If you have a micrometer, it is advisable to check the uniformity of the sheet along the entire cut line, measurements are taken at three points at least.
The presence and data of the certificate are checked without fail, given the high price of C-8 corrugated board with polymer protection, you can purchase a fake or substandard in any unofficial store. The conditions for loading, delivery and unloading are negotiated separately, the panels themselves weigh a little, but it is difficult to carry them uncut. It is easier for private developers to cut them in stock.

Almost all manufacturers of rolled metal products offer to buy a profiled sheet with such a wave size. The best reviews have the products of the factories Metal Profile, Grand Line, Tavros, SPK, Promintekh, Stinergy, Still-Pass, sold wholesale and retail. If necessary, the material is cut into pieces of the desired size from 0.5 to 12 m long (including diagonally). When comparing the proposed prices, attention is paid to the indicated units of measurement, each company has its own (price per sheet, 1 m2 or 1 running meter).
Modern building materials in terms of technical characteristics and operation features have taken a leap forward in recent years. The same applies to corrugated board. One of the most popular is the C8-1150 model. It is versatile and at the same time it can be purchased at more than affordable prices. Most often it is used in the following cases:
- for the construction of fences;
- for installation of suspended ceilings;
- as a facing material for walls or ceilings;
- as roofing.
Manufacturing standards according to GOST
As you know, the quality standard of any building material is GOST. Only corrugated board agreed with it can be used in construction.
For corrugated board of category C-8, one of the manufacturing features of which is cold rolling, GOST - 24045-95 is established. The initial raw material for manufacturing can serve as:
- rolled cold-rolled steel grades 01 and 220-350, for which the following position is established in accordance with GOST - 52246-2004. Steel has a protective lining of zinc (GOST 14918);
- zinc steel with a polymer coating with a position in accordance with GOST - 52146 steel with a coating of paint and varnish (30246).
The aforementioned corrugated board is manufactured in a specialized production using the following equipment:
- decoiler, which is the main support of the coiled steel;
rolling machine, which is designed to perform a dominant function in production; - steel scissors, the device of which is based on the principle of the guillotine;
a device adapted to receive the finished material; - oil station, which provides C8 corrugated board with mobility and ease of use;
- remote control equipped with a remote operation system.
It is important to note that the manufacturing process of this building material is fully automated. The human factor is necessary only to control the production process and, if necessary, troubleshoot the system.
Deciphering the name of the S-8 corrugated board
For those who are busy building their own house for the first time and are new to the notation system, this information will be relevant. Suppose you choose corrugated board and see the designations on it: C8 - 1150 - 0.5. This will mean the following:
- C - wall, what to say that the walls are the main place for the use of building material;
- 8 - the height of the corrugated board profile (it can also be 10, 12, 14 mm);
- 1150 - profile width, taking into account the margin (in this case, the most used parameters are given);
- 0.5 is the thickness of the source material, in this case rolled metal.
Specifications of S-8 corrugated board
Technical characteristics of S-8 corrugated board according to GOST do not have high strength indicators in case of dense pressure on it. However, in this case, this is more of a plus than a minus, since being light enough and moderately strong, it is easy to install. As an example, we can cite only one square meter of C8 - 1155 - 0.5 corrugated board, which weighs more than five kilograms.
As for the width of a given building material, it is nothing more than the difference between the total width of the corrugated board and the width of the overlap between adjacent sheets of material.
multiply the mass of material by the area of the sheet and by the estimated number of steel sheets.
The use of corrugated board in construction
Due to the fact that corrugated board is not able to withstand heavy loads, the following main areas for its application can be distinguished:
- finishing of the facing part of the building;
- as one of the components for SIP panels;
- use as an additional temporary building during the main construction (warehouse, shower, toilet);
- fence for the area, which is characterized by strong winds and frequent precipitation.
