Profiled sheet is a popular type of cladding made of galvanized steel with a thickness of 0.4-0.9 mm. Profiled sheet is produced using cold rolling technology. During processing, it is given various shapes to increase rigidity. To recognize the technical characteristics of their products, manufacturers use the marking of the corrugated board.
The relevance of marking corrugated board
It is difficult for a person who does not understand construction nuances to navigate the wide range of products presented. This situation complicates the selection of materials. To level the problems with the choice, a system for marking corrugated board has been thought out, which can be deciphered as follows:
- The first letter indicates the type of material and scope, for example, roofing or suitable for building a fence.
- The first digit deciphers the height values from 6 to 114 mm. The higher this parameter, the more loads the sheet can withstand.
- The second number indicates the thickness - from 0.45 to 0.9 mm. Bearing profiled sheet is made of thick steel, for walls - from thin.
- The third number indicates the width of the profile material. The indicator depends on the height of the profile - the larger this parameter, the narrower the corrugated board. The maximum values are 1150 mm.
- The last digit in the marking code is not always prescribed by the manufacturer, since it indicates the maximum length, which reaches 12000 mm.
Bent profiled sheets with trapezoidal corrugations are produced in accordance with GOST 24045-2016. The regulatory document contains technical conditions for the manufacture of products. Gosstandart also defines the requirements for raw materials, coating, completeness, dimensions, etc.
Decoding of marking
The material is also covered with an aluminum layer, which is reflected in the marking as "AL", or aluminum-silicon - "AK". These types of spraying increase the wear resistance of the sheet, so the material belongs to the premium class.
To decipher the marking of the corrugated board, it is enough to familiarize yourself with the alphanumeric designations.
Letters
The first in the designation is the brand of corrugated board, consisting of one letter or a set. To decipher the letters, you must also know the purpose of the material. After reviewing the information, you can independently choose the appropriate material, according to the requirements and purposes of construction. The basic classification is as follows.
- MP - metal polymer. This material is highly durable. It is used as a decorative protection of the product. The characteristics include the size and type of wave. In terms of basic properties, it is similar to polycarbonate used to create transparent roof inserts. This type of profiled sheet is often used for arranging the roof in the attic. Strength depends on the thickness of the product. The most reliable models are capable of withstanding wind forces up to 25 m / s.
- H - carrier. The designation of corrugated board with this letter indicates that the material is suitable for covering roofs, fences, and is also used for cladding frame houses.A high level of stiffness and strength is achieved by increasing wave parameters and central furrows. The corrugated product is able to withstand strong gusts of wind, snowfalls and other atmospheric phenomena.
- C - wall. Material with this letter has low bearing properties. The product is used only for facing structures from the outside. Due to its small thickness and relief, the profiled sheet is vulnerable to physical impact and wind.
- NS - bearing-wall. The presence of such markings on a corrugated product expands the field of application. The material is used for cladding houses, industrial buildings, sheds, roofs and permanent formwork. The presented brand is available for purchase at the construction market or in a store.
Product dimensions are indicated in sequence - height, width, thickness (mm).
Numbers
Deciphering the marking of the profiled sheet, you can see that the code consists of a set of letters and a combination of numbers that indicate the technical characteristics of the corrugated product. The first symbols indicate the height of the profile, measured in millimeters - 20-75. The higher the indicator, the more pronounced the structure and relief of the product.
The second number is also indicated in millimeters and shows the user the strength properties and the degree of stiffness. The third symbol indicates the mounting width, which may differ depending on the brand. The last figure stands for the maximum length of the material. All indicators are measured in millimeters.
Popular brands
Corrugated products can be used not only for cladding buildings and erecting fences, but also for the manufacture of awnings and canopies. When choosing a model, pay attention to the alphanumeric dialing.
C10
The most popular model of a corrugated product, which in terms of performance is not inferior to polymer siding panels. However, due to the small thickness of the steel, the material does not have high reliability parameters. The brand is inexpensive and imitates the lining in a painted form.
C17
Such marking is often denoted by a corrugated board with a galvanized coating. The model is universal in use and has a pronounced structure. They use building material for cladding frame structures, creating sheds and roofs on farm buildings. Sheets are allowed to be painted and decorated on both sides with a protective coating.
C18
Wall material with increased height. Products are made from durable steel. Regardless of belonging to the load-bearing category, the corrugated product is used in the creation of pitched roofs in regions with low atmospheric precipitation. The material is also suitable for the construction of temporary fences.
НС 44 1000
HC 35
A universal version of profiled sheets. A flooring with this designation has a long service life. The scope of application of the HC35 is quite wide, for example:
- construction of temporary fences;
- construction of fences;
- the creation of roofing;
- outside wall cladding;
- arrangement of partitions in utility rooms, warehouses, pavilions and hangars.
The thickness of the galvanized corrugated board of 0.8 mm ensures the reliability of the structure. The owner does not have to worry about the safety of the structure even in aggressive environmental conditions.
The manufacturer must attach an accompanying document with technical designations to each shipped batch of products.
H 57750
This marking designates corrugated steel products with high load-bearing characteristics. The optimal profile height makes the sheets an excellent option for roofing. The installation width is 750 mm, which makes it convenient for horizontal and vertical installation.Using material H 57750 on roofs, you can forget about leaks for a period of 10-15 years.
