Profiled c8 - sheet dimensions, technical characteristics
The galvanized steel sheet is considered to be one of the most practical and versatile building materials used in the construction of residential and industrial buildings, barriers, roofs. Profiled C8-1150 - one of the most affordable brands of this material, which was originally intended for wall cladding and ceilings, and therefore has a low profile, but is also often used to overlap steeply sloping roofs. In this article we will tell about the technical characteristics, standard sheet sizes and features of the use of this material.
Production technology
Wall profiled mark C8 is made by cold rolling of steel billets with a thickness of 0.7-0.8 mm, according to the requirements of TU 1122-079-0249468080-01 or GOST 24045-94. The line for the production of this material includes a decoiler, in which a roll of 220-grade steel sheet is installed, a molding machine that gives the desired relief to the workpieces, as well as guillotine shears that produce sheet cutting to size, and a painting shop. The process of making a professional sheet is usually fully automated, so the quality standards are maintained at a high level. For production of a professional flooring c8 use the following types of raw materials:
- Cold rolled rolled steel grades 220-350, manufactured according to GOST R 52246-2004, with a protective coating of zinc, applied according to the requirements of GOST 14918.
- Galvanized steel with a protective and decorative polymer coating according to GOST R 52146-2003 or one-sided paint coating according to GOST 30246.
Please note that the c8 profile sheet is officially classified as “wall”, therefore it has a small profile height of only 8 mm, as well as a relatively low bearing capacity. Knowing the technical characteristics, you can use a galvanized C8 corrugated flooring for the construction of the roof, however, this should be foreseen when designing the roof frame.
Quality standards
The professional sheet C8-1150 is an inexpensive material, so it is very popular in the cottage and garden construction, which is most often done by hand. Unfortunately, the products of this brand are faked more often than others because of the constant demand, so buyers often suffer because of its poor quality. When purchasing a material, keep in mind that the sheet size and appearance may have the following errors:
- On the outer side of the profiled sheet, that is, on the protective-decorative coating of the material, there may be slight abrasions, but they should not violate the integrity of the layer.
- The height of the profile material can have a deviation of 0.1 mm, the width of the sheet - 0.8 mm, the length - 10 mm upwards or downwards.
- The professional sheet of this brand should not have a wavy sheet more than 1.5 mm on flat areas and more than 3 mm on the edges and limb.
Important! All necessary information about the properties of the material can be found in the label, which supplies all products according to the requirements of GOST. The letter "C" in the abbreviation means that the material belongs to the wall category, the figure 8 indicates that the profile height is 8 mm, and the figure 1150 indicates the useful width of the profiled sheet.

Technical details
Profiled grade C 8 refers to the materials of "economy class", so it is actively used at all stages of construction. ABOUTHowever, the technical characteristics of the profiled sheet in this category are designed taking into account 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. The professional sheet C8-1150 has the following description:
- Appointment - wall.
- The shape of the profile is a trapezoid, the top of which is already the base.
- Profile height - 8 mm.
- Useful (working) sheet width - 1150 mm.
- The initial thickness of the steel billet used for the production of the material is 0.4-0.6 mm.
- Weight per square meter of 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 a professional sheet is deciphered, it is easy to determine the difference between professional flooring c8 and c20. Both of these materials are of the wall type, the difference is only in the height of the profile. The larger this parameter, the greater the carrying capacity, but the smaller the working width of the product.

Use cases
Given the technical characteristics of the professional sheet brand C8-1150, you can use it 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 adapted for the effects of static weight loads. Under certain conditions, this material is used for:
- Facades of residential, commercial and industrial buildings.
- Production of sandwich panels.
- The construction of small outbuildings (barns, temporary shelters, cabins, toilets).
- Construction of fences and fencing in areas with low wind load.
- The construction of the roof.
Note that the professional sheet of this brand can only be used for roofs that have a slope of more than 40-45 degrees. To increase the bearing capacity of the material, it is necessary to strengthen the truss frame and the crate of the structure. In addition, it is recommended for this task it is recommended to use a professional flooring with a polymer coating, as it is better resists corrosion and mechanical damage.
