C8 professional flooring for a fence and walls. Characteristics and dimensions of C8 corrugated board, types of polymer coatings, prices and fastening rules How much does C8 profiled sheet weigh 0.45

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 products from thin sheet steel 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 specifications regulated by GOST 24045-2016, the main ones taken into account when purchasing, installing and operating 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, %.
Maximum operating temperature without loss useful properties and aesthetics - 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 building codes such rental 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. Demand is explained as 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. Profiled sheets with a polymer coating 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 one- and two-sided layers, the former are represented by a wider colors, the latter are valued for equally attractive appearance at 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 others. 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. Top Reviews has products from Metal Profile, Grand Line, Tavros, SPK, Promintekh, Stinerzhi, Still-Pass factories, sold wholesale and retail. If necessary, the material is cut into pieces right size length from 0.5 to 12 m (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).

One of the most common types of corrugated board is S8-1150 corrugated board.

C8 profiled sheeting is made from galvanized cold-rolled sheet steel and is characterized by a sheet thickness of 0.35-0.7mm and a profile height of 8mm. The metal sheet itself is protected by a zinc layer, and the zinc can be protected by a polymer layer.

Polyester is used as a protective polymer coating: glossy or matte. The choice of polyester colors is possible from a standard set or according to the RAL scale. This makes it possible to find options for shades that fit into the surrounding landscape and blend harmoniously with design decision houses or cottages.
For the manufacture of unpainted profiled sheet C8, galvanized sheet metal is used.

The affordability of corrugated board of this brand is explained by the low cost of production - the height of the profile is small, therefore, a smaller amount of metal is consumed per 1 m2 of material with the same sheet thickness as products of other brands.

The figure below shows the dimensions of the c8 corrugated board for the fence

C8 corrugated board is used for the construction of fences, as well as for cladding the facades of non-residential construction projects. A beautiful coating of durable polymer and the correct geometry of the wave provide the fence with an aesthetic appearance, the territory protected by a solid fence made of profiled sheet is inaccessible to prying eyes.

Galvanized steel profiled sheet is considered one of the most practical and versatile building materials used in the construction of residential and industrial buildings, barriers, roofing. S8-1150 corrugated board is one of the most affordable brands of this material, which was originally intended for wall and ceiling cladding, and therefore has a low profile, but is also often used to cover steep roofs. In this article, we will talk about specifications, standard sizes sheet and features of the use of this material.

Wall decking grade C8 is made by cold rolling from steel billets, the thickness of which is 0.7-0.8 mm, in accordance with the requirements of TU 1122-079-02494680-01 or GOST 24045-94. The line for the production of this material includes a decoiler, in which a roll of 220 grade sheet steel is installed, a forming machine that gives the blanks the desired relief, as well as guillotine shears that cut the sheet to size, and a painting shop. The manufacturing process of profiled sheets is usually fully automated, so quality standards are maintained on high level. For the production of corrugated board c8, the following types of raw materials are used:

Cold-rolled coiled steel grades 220-350, manufactured in accordance with GOST R 52246-2004, with a protective zinc coating applied in accordance with the requirements of GOST 14918.
Galvanized steel with a protective and decorative polymer coating in accordance with GOST R 52146-2003 or one-sided paint coating in accordance with GOST 30246.

Please note that the c8 grade profiled sheet officially belongs to the “wall” category, therefore it has a small profile height of only 8 mm, as well as a relatively low bearing capacity. Knowing the technical characteristics, it is possible to use C8 galvanized corrugated board for roofing, however, this must be taken into account when designing the truss frame.

Quality standards

Profiled sheet C8-1150 is an inexpensive material, so it is very popular in country and garden construction, which is most often done by hand. Unfortunately, the products of this brand are counterfeited more often than others due to constant demand, so buyers often suffer because of its poor quality. When purchasing material, keep in mind that sheet dimensions and appearance may have the following errors:

On the outside of the profiled sheet, that is, on the protective and decorative coating of the material, there may be small abrasions, but they should not violate the integrity of the layer.
The material may have a deviation of 0.1 mm along the profile height, 0.8 mm along the sheet width, and 10 mm up or down along the length.
The profiled sheet of this brand should not have a sheet waviness of more than 1.5 mm in flat areas and more than 3 mm on the edges and bends.

Important! All the necessary information about the properties of the material can be found in the marking, which is supplied to all products in accordance with the requirements of GOST. The letter "C" in the abbreviation means that the material belongs to the wall category, the number 8 indicates that the profile height is 8 mm, and the number 1150 indicates the useful width of the profiled sheet.

Technical data

The professional flooring of the C 8 brand belongs to the "economy class" materials, therefore it is actively used at all stages of construction. However, the technical characteristics of the profiled sheet of this category are developed taking into account the fact that it will be used as a wall, that is, it has a small profile height, light weight, is not equipped with additional stiffeners, and is also adapted to dynamic wind loads. Profiled sheet S8-1150 has the following description:

Purpose - wall.
The profile shape is a trapezoid, the top of which is narrower than the base.
Profile height - 8 mm.
Useful (working) sheet width - 1150 mm.
The initial thickness of the steel blank used for the production of the material is 0.4-0.6 mm.
Weight square meter material - up to 5.6 kg / m2.
Length - from 0.5 to 15 meters with a cutting step of 50 cm.

Remember! Knowing how the marking of the profiled sheet is deciphered, it is easy to determine how the c8 and c20 corrugated board differs. Both of these materials belong to the wall type, the difference is only in the height of the profile. The larger this parameter, the greater the bearing capacity, but the smaller the working width of the product.

Use cases

Given the technical characteristics of the S8-1150 profiled sheet, it can be used not only for wall cladding, but also for other construction operations. It is important to remember that it has a relatively low bearing capacity and is not suitable for static weight loads. Under certain conditions, this material is used for:

Finishing of facades of residential, commercial and industrial buildings.
Manufacture of sandwich panels.
Erection of outbuildings small size(sheds, makeshift houses, change houses, toilets).
Construction of fences and organization of fences in areas with low wind load.
Roof erections.

Please note that the profiled sheet of this brand can only be used for roofs whose slope exceeds 40-45 degrees. To increase the bearing capacity of the material, it is necessary to strengthen truss frame and the crate of the structure. In addition, it is recommended to use polymer-coated corrugated board for this task, as it better resists corrosion and mechanical damage.

Video instruction

One of the multi-purpose and widely used modern building materials is corrugated board.

Since the material has a relief surface, which makes it the owner of exceptional longitudinal and transverse rigidity, it is used almost everywhere.

Its other qualities are also captivating: strength, ductility and corrosion resistance.

What is corrugated board made from?

For the manufacture of corrugated board, the same material is used as for the metal tile - a steel sheet.

It's just that this sheet is rolled by cold rolling through other machines and the appearance of the corrugated board is different.

If the metal tile is an imitation of ceramic tiles, then the corrugated board imitates slate.

Then a layer of zinc is applied to the surface of the sheet to protect it from corrosion and a layer of polymer anti-corrosion coating.

Depending on the purpose of operation, corrugated board is usually divided into several types:

Mark "N". In its marking, the presence of the letter H indicates that it is a "bearing" material. The thickness of the steel sheet is the largest possible. The wave height is also maximum.
In order to make this material even more rigid, additional grooves are made on its surface. Grade H has proven itself well in the manufacture of heavy cargo containers, as well as in the construction of hangars, garages, warehouses, workshops, fences, and other facilities and structures.
It is this corrugated board that is most often used for outer skin walls of buildings, production of gates, fences. Sometimes such a corrugated board is used in roofing work.
But this happens very rarely, since such material weighs a lot.
Professional flooring "NS". That is, a load-bearing wall material. Such material is the most versatile of the types of corrugated board. The thickness of such a profiled sheet is averaged.
It also has a wave surface of medium height. The profiled material of the brand "NS" is distinguished by increased rigidity, and can be used for finishing ceilings, walls, ceilings of any kind, as a roofing material.
Mark "C". It is already clear from the marking that this is wall corrugated board. And for wall decoration, it is these profiled sheets that are most often used. The small thickness of the product greatly simplifies installation.
As a rule, such corrugated board is used in conjunction with various heaters: polystyrene foam, ecowool, mineral wool or natural insulation.
Produced profiled sheet brand "C" medium and small thickness. The height of the corrugation is average, which makes this material very convenient for roofing.
A roof made of this material is durable and reliable. It easily withstands any load under any impact.
Such a bearing element is often used as flooring on scaffolding: such material can easily withstand a large weight load.

General characteristics

For the production of cold-formed steel profiles of trapezoidal shape, they are made from cold-rolled steel sheets (GOST 24045-94) on bending machines.

The thickness of the sheets is from 0.4 mm for wall corrugated board to 1.5 mm for bearing corrugated board.

The presence of additional stiffeners, as well as grooves, make this material very resistant to various aggressive environments and any kind of load.

But this material, despite its high mechanical strength, is one of the lightest building materials.

The professional flooring of the H brand is used in construction everywhere.

It is also often used in restoration and repair work.

If the corrugated board is used for finishing roofing, then this is a material of grade H or HC.

It is able to easily support the weight of a person (which is very important during installation) or any thickness of snow cover.

Load, mechanical or chemical influence, has practically no effect on profiled sheets.

The presence of a galvanized coating and a polymer film make steel sheets not susceptible to moisture, sudden changes in temperature, and corrosion.

It is possible to transport and mount a professional flooring at any weather.

Installation of corrugated board does not require complex construction tools and special equipment.

Material weight

The weight of a steel profiled sheet depends on its thickness, the thickness of the zinc and polymer coatings.

After all, each material has its own weight.

Self-tapping screws for fastening

The fastening of the profiled steel sheet to the elements of the crate is carried out using self-tapping screws.

Or, as the builders say, self-tapping screws.

A self-tapping screw is a type of fastener, which is a steel rod with a head and a triangular external thread.

In the process of fastening, such a screw independently cuts a thread inside the hole.

This type of fastener differs from screws and screws in that the thread is applied to the entire cylindrical surface of the rod.

To date, the range of self-tapping screws for fastening the profiled sheet is very wide.

And you should know that for each type of work there is a separate type of self-tapping screws, which differ in their parameters and characteristics.

That is, on the roof and a self-tapping screw for mounting on the fence - these are different fasteners.

And if you get the wrong fasteners, it is difficult to guarantee the strength and reliability of fastening the sheets.

Self-tapping screws are made of high quality stainless or galvanized carbon steel.

The self-tapping kit also includes a gasket made of neoprene.

The presence of such a gasket allows you to make the attachment point airtight.

Most manufacturers of fasteners, in order for the design of the fence or roof to have a more presentable appearance, cover the head of the self-tapping screw with polymer paint.

The paint used is the same as when painting sheets.

Therefore, after installation, the self-tapping screw is almost invisible.

Types of self-tapping screws for fastening

In total, there are three types of self-tapping screws for fastening a profiled sheet:

For fastening products to wooden frames. For such a self-tapping screw, the thread pitch is rare, which makes it possible to ensure the strength of the fastener. Such a self-tapping screw can be screwed without problems even into the hardest wood.
For fastening the product to metal. Also, such a self-tapping screw is used if it is necessary to attach a profiled sheet to a structure that is affected by strong wind loads. The thread pitch on such a self-tapping screw is also rare. But in the manufacture of a drilling tip, a special sharpening is made, which, during the work, eliminates the violation of the structure of the material.
For fastening on the roof of additional and ridge elements. These screws are very long.

All three types of self-tapping screws are equipped with a special drill tip, thanks to which it is not necessary to pre-drill a hole in the fastened elements.

And the hex head is easily fixed in the screwdriver's chuck, which greatly simplifies the work process.

Weight and cost of screws

The weight of self-tapping screws and their cost depend on their diameter and length.

A measure of the weight of a self-tapping screw is a kilogram per 1000 fasteners.

Depending on the length of the product, the weight of one thousand self-tapping screws can range from 18.5 to 41.67 kg. That is, one self-tapping screw can weigh from 18.5 to 41.67 grams.

When fixing the corrugated board on the roof, 9 self-tapping screws are consumed per sheet.

To fix the sheet on the fence, 6 self-tapping screws are enough.

Since the sheets are overlapped, some self-tapping screws hold 2 sheets at the same time.

Prices for self-tapping screws also depend on the size, and are in the range of 1.6 - 3.0 rubles per unit.

Do-it-yourself video about a roof made of corrugated board.

C8 corrugated board is one of the most popular types of corrugated board, the areas of use of which are practically unlimited in modern construction.

The main advantage of this brand of corrugated board is its low cost, which makes it difficult to find a more economical material for wall cladding, fence construction and false ceiling installation.

Despite the low bearing capacity of the C8 profiled sheet, it is nevertheless often used for roofing installation - for example, for pitched roofs, the angle of inclination of which is more than 30-40 degrees.

Technical characteristics of corrugated board C8

The production of C8 grade corrugated board is carried out by the method of cold rolling of thin sheet steel with a thickness of 0.5-0.7 mm in accordance with the requirements of GOST 24045-94 and TU 1122-079-02494680-01.

As for other varieties of this building and finishing material, for the production of C8 corrugated board, both cold-rolled steel (grades 01, 220-350 according to GOST R 52246-2004), galvanized according to GOST 14918, and galvanized steel with a polymer coating (GOST R 52146-2003) or painted steel (GOST 30246).

The surface of C8 corrugated board is a corrugated relief with 8 mm high trapezoids (which is reflected in the brand name), while the width of the base of the trapezoid is 62.5 mm, and the distance between two adjacent corrugations is 52.5 mm. In addition to the abbreviated nomenclature of corrugated board (C8), according to the requirements of GOST 24045-94, there is also an expanded marking of the profiled sheet.

For example, the designation “profiled sheet S-8-1150-0.5” means that we are talking about wall corrugated board with a trapezoid height of 8 mm, having a useful (working) profile width of 1150 mm and made of steel with a thickness of 0.5 mm. The working width of the corrugated board is determined as the difference between the total width and the value of the longitudinal overlap of the corrugated board with adjacent sheets.

The width and thickness of the steel used for the production of corrugated board are the determining factors for its weight, which is considered very small for this brand. For example, the mass of one square meter of profiled sheet C8-1150-0.6 is only 5.57 kg.

The dependence of the mass of one square meter of C8 corrugated board on its characteristics is presented in the following table:

Profiled brand	Weight 1 p/m (1x1.25 m), kg	Weight of 1 m² profiled sheet, kg

This table is convenient to use, for example, when it is necessary to calculate the weight of a batch of purchased material: for this mass of a linear or square meter of corrugated board, you simply need to multiply by the length of a sheet 1 or 1.25 meters wide, or by the area of a sheet of arbitrary width, and then by the total number of sheets .

Profiled brand	Sectional area, sq.cm	Reference values per 1 m width		Workpiece width, mm
Profiled brand	Sectional area, sq.cm	Moment of inertia	Moment of resistance	Workpiece width, mm

But the most basic technical characteristic of C8 corrugated board is the ability to withstand loads of a certain size. We have already mentioned that, although in most cases this brand of profiled sheet is used for the construction of fences, one should not neglect such an economical option for roofing.

The following table shows the maximum permissible uniformly distributed loads calculated for the most common profiled sheet support schemes - single-span, two-span, three-span and four-span.

Thickness of steel profiled sheetC8	Span, m
Thickness of steel profiled sheetC8	Span, m	1 span	2 spans	3 spans	4 spans

The angle of inclination of the roof for cladding with corrugated board C8 must not be less than 15 degrees, while the profiled sheet is mounted on a solid cladding.

We offer you to see how the production of C8 corrugated board is carried out at our enterprise:

Application of corrugated board C8

Profiled sheet grade C8 is usually not used to create load-bearing structures due to the high windage and the smallest of all possible wavelengths, which causes its limited ability to withstand the load. However, nevertheless, its scope is quite wide and includes the following areas:

Finishing the facades of buildings
Production of sandwich panels
Construction of auxiliary facilities on summer cottages(sheds, warehouses, showers, utility rooms)
Construction of fences in areas where strong and gusty winds are not typical

In particular, polymer-coated C8 profiled sheeting is relevant for solving these problems, since it is not only more aesthetically pleasing, but also has a long, trouble-free service life compared to the galvanized version. For example, if the service life of a C8 profiled sheet with a galvanized coating is approximately 10-15 years, then the polyester applied to its surface extends the service life to 2-3 decades. The use of pural as a coating can extend the life of C8 corrugated board even up to half a century.
