All about the marking of corrugated board

When choosing a corrugated board, special attention should be paid to its marking. Its decoding allows you to determine the purpose of the material, its bearing capacity, indicates the height of the corrugation. It is worth learning a little more about how to determine the grade of steel and the corrugated board itself, what to pay special attention to.

The first in the designation of corrugated board is its mark, which looks like one or more letters. The decoding of the letters determines the purpose for which the material is intended. The main classification of the profiled sheet looks like this.

• "MP". This is the designation of a metal polymer - a material that has a durable decorative and protective coating on the outside. In many respects, including dimensional parameters and wave type, it matches the polycarbonate used to create transparent roof inserts. A professional sheet of this type is used for the construction of roofs over attic floors. The strength of the decorative and protective coating varies depending on its thickness: the most reliable options can withstand significant operational loads.

• "H". This designation hides the bearing type of profiled sheet, which is considered a universal option for creating roofing, fences, cladding of frame buildings and structures. Increased rigidity and strength of the material is achieved by increasing the height of the waves, as well as due to a special groove in the center of each corrugated element. Such a coating is not afraid of wind loads, heavy snowfalls, and other external threats.

• "WITH". This letter denotes a wall material with not too high bearing characteristics. It is suitable exclusively for use as the exterior cladding of buildings. The low thickness of the profiled sheet and the poorly expressed relief make it vulnerable to shock loads and strong winds.

• "NS". The mark of the profiled sheet material with this designation is read as non-material-wall. This significantly expands the scope of the material. The professional sheet "NS" is used for the external cladding of buildings and structures, the formation of roof structures and sheds, the manufacture of permanent formwork.

When studying the marking of the profiled sheet, you can pay attention to the fact that the designations consist of a combination of letters and numbers. They determine not only the purpose, but also the individual characteristics of the material. Immediately after the letters are numbers indicating the height of the profile. It is marked in millimeters: from 20 to 75. The higher this indicator, the more intense the relief will be.

After the designation of the profile height, the thickness of the steel sheet is indicated. This indicator is also indicated in millimeters. It is important because it affects the strength and stiffness of the material. Further, the marking indicates the installation width of the material, which differs from the total in the smaller direction. The last number in the row is the maximum sheet length. All these indicators are indicated in millimeters.

Profiled sheeting made of durable steel is available for sale in a fairly wide range. Knowing the features of its labeling and being able to read it, you can easily determine which option is suitable for making a visor, creating a fence, wall cladding. The main value is always given to the combination of the letter and the first digit, which indicates the height of the profile. The most popular options are worth considering in more detail.

This type of corrugated board is most often used as an alternative to polymer siding. Thin steel and the minimum profile height do not provide it with sufficient reliability.

Most often, a profiled sheet with such markings is sold in galvanized form. It is versatile, has a pronounced relief, perfect for forming wall cladding, creating awnings or roofing on outbuildings. The sheets lend themselves well to coloring, and the decorative and protective coating can be applied from 1 or 2 sides.

This type of wall covering has an increased profile height and is produced from stronger and thicker steel. Despite the fact that its bearing capacity is rather small, the material is successfully used in the construction of sheds, pitched roofs with low snow load. It is also suitable for the construction of temporary fences.

Decking of this type is considered the most popular for use in household needs. Its relief is well pronounced, which makes it possible to provide an optimal ratio of strength characteristics and rigidity. Application and purpose are similar to other sheets of the wall category.

A professional sheet with this marking refers to the universal options. It has an assembly width of 1 m. Its main purpose is the construction of fences and barriers, the arrangement of roofing. This brand is considered the best choice in terms of price and quality.

A popular universal type of corrugated board. Sheets with such markings have proven themselves well in operation as elements of fences: permanent or temporary. They are suitable for roofing, construction of external walls and internal partitions in hangars, shopping pavilions. The height of the profile ensures the rigidity of the structure, and the thickness of the galvanized sheet of 0.8 mm allows you not to be afraid for its integrity even under significant operational loads.

This type of wall material has a pronounced relief, it is made of galvanized steel of increased thickness. Despite the fact that the profiled sheet is designated as a wall sheet, it is widely used for other household needs.

Sheets with such markings have excellent load-bearing properties. The high profile profile makes them a good solution for use on the roof, and the installation width of 750 mm provides sufficient comfort for horizontal and vertical installation. The roof covered with profiled sheet "H 57750" makes it possible to guarantee the absence of problems with leaks for a period of more than 10 years.

Since the marking of the profiled sheet determines its purpose, experts prefer to distinguish categories of such products according to their purpose. Some materials are considered universal: their rigidity and strength are always higher than those of budget counterparts. Popular options in this category include the following grades of corrugated board.

• "H75". Rigid corrugated sheet made from thick sheet steel with a profile height of 75 mm is considered the best choice for creating durable roofing.The relief surface of the material withstands the maximum intensity of operational loads. Sheets of this brand are produced in galvanized and polymer versions, there are special grooves on the shelves that provide increased strength. The areas of their application also include the formation of permanent formwork, reinforcement of walls of buildings and structures.

• "C8". A thin profiled sheet with an original relief and low shelf height is distinguished by its attractiveness and unusual appearance. It is widely used in exterior wall decoration of buildings. Steel rolled products used in the production have a thickness of 0.35 to 0.7 mm, can have a galvanized or polymer coating. Such a sheet is suitable for the construction of suspended ceiling structures, can be used to form canopies, unloaded roofs and awnings.

• "H60". A universal bearing profiled sheet with this marking has a trapezoidal relief, made of thick rolled steel. The material uses special grooves - stiffeners that increase the resistance to wind and snow loads. It has a wide range of applications, suitable for the construction of permanent fences on the foundation.

• "НС10". Lightweight universal profiled sheet with a low relief height is suitable for use as a material for wall cladding, false ceilings and other architectural elements. With some restrictions, it can be used in the construction of awnings and roof structures. This professional sheet is not designed for serious loads.

• "H144". Such marking is quite rare and only in specialized varieties of professional sheets. The height of the profile is maximum here, it is focused on the construction of industrial facilities with a significant amount of spans. The rigidity of the material ensures that the use of auxiliary supports can be minimized.

Knowing how to read the marking of the profiled sheet, you can easily understand the features and purpose of the material when choosing it. Such knowledge will also be useful in the event that you need to purchase individual elements for replacement, repair of a roof or a fence.
