The right choice of corrugated board for the roof of the house

Decking is a metal embossed sheets with a colored polymer coating that protects the metal from corrosion and extends its service life. Despite the apparent simplicity of the structure, the corrugated board is presented in different versions, and all brands differ from each other in characteristics, purpose and other properties. Therefore, when choosing, they are guided by several criteria and features of the grades of profiled sheets.

Types of corrugated board and their features

Roofing requires the use of high-quality materials, since the roof is always exposed to climatic factors and must be durable. Three main types of material meet these requirements:

• galvanized sheets without a colored polymer coating, which are inexpensive and are often used to equip the roofs of utility rooms;

  

  Galvanized sheets are convenient for arranging the roofs of auxiliary buildings

• wall (C) or bearing (H) material with a polymer protective coating is suitable for roofs of residential buildings;

  

  Polymer coating protects metal from corrosion

• roofing sheets can be bent, rolled or with textured embossing and differ in appearance, profile shape.

  

  Roofing sheets can be of any color

All variants are made from coiled steel, and the embossed surface is created by cold forming. At the same time, the technical characteristics of the sheets depend on the steel thickness, configuration and profile depth. High-quality corrugated board for the roof of the house must meet the following indicators:

• profile height from 20 mm;
• the presence of a capillary groove for improved moisture removal (the supporting corrugated board has a groove, and there is no capillary outlet on the facade material);
• the polymer coating should not have scratches, different thicknesses and other defects;
• there should be no dents or deformed areas on the sheets of material;
• it is best if the length of the sheet matches the length of the slope, which avoids unnecessary overlaps.

Description and characteristics of grades of corrugated board for roofing

The main types of corrugated board for creating roofing differ in the distance between the ridges and the thickness of the metal. The lower the first and higher the second indicator, the stronger and more durable the metal sheets. This also affects the bearing capacity of the material, since snow, rain and wind have a significant effect on the roof.

The corrugated board protects the roof well from climatic factors

The demanded brands of metal sheets for the roof of the house have the following characteristics:

• the material of the S-21 brand is characterized by high rigidity, and its installation is carried out on a crate with a step of 90 cm. It can be with a polymer coating or unpainted. The useful width of standard sheets is 1000 mm, and the length can be in the range from 1 to 12 m. The profile of this brand is made in the form of a trapezoid and has a height of 21 mm, the thickness of steel is from 0.4 to 0.8 mm. The weight of 1 m ² can be from 4.45 to 8.4 kg, respectively, the minimum and maximum thickness;

  

  S-21 corrugated board is universal and is used for both roofing and facades

• The RN-20 has analogs under the C17 and MP20 markings, which have practically equal characteristics. Sheets can be galvanized or color-coated. During installation, the lathing step of up to 0.8 m is observed. The height of the trapezoidal corrugation is 20 mm, and the sheets are produced up to 12 m long, 1100 mm wide;

  

  The parameters of the MP20 brand corrugated board allow the use of this material for the roof

• grade S-44 has additional stiffening ribs, is made of steel with a thickness of 0.5-0.9 mm, the height of the corrugation is 44 mm, the useful width is 1000 mm, and the length of the sheet can be from 0.5 to 12 m. wall type, can be galvanized or painted with a polymer compound for corrosion protection;

  

  44 mm sheet profile provides hardness of the coating

• NS-35 material belongs to the universal type of corrugated board, has a corrugation 35 mm high, useful width 1000 mm. The thickness of the steel is between 0.4 and 0.8 mm. Sheets can be zinc or polymer coated. The material has a trapezoidal profile, which is optimal for roofs with any slope.

Features of marking

All types of profiled sheets have specific markings that allow consumers to easily navigate when choosing among a variety of sheet options. The marking indicates all the main parameters and characteristics of the material, making it very easy to understand for what purposes the sheet is intended. This is determined using the letters that the marking contains. There are several basic classification options:

• "N" - the bearing type of corrugated board, which is the most durable of all options. The material with this marking has an additional groove along the profile, which increases the rigidity of the sheets. Elements marked "H" have the highest profile height, significant steel thickness.
• "C" denotes a wall type of material used for cladding facades, creating lightweight buildings. The wave height can be from 10 to 44 mm, which is significantly lower than for roofing material. Sheets "C" are made of steel with a thickness of up to 0.7 mm, therefore they are not suitable for roofs subject to significant loads.
• "NS" - material with average parameters between the two above options. Universal sheets are suitable for roofing, fences, lightweight structures. The polymer coating enhances the strength and rigidity of the structure.
• "MP" is also a universal option used for roofs, sandwich panels, partitions, etc. The sheets are presented in a galvanized version and with a polymer coating. For roofs with any type of slopes, products marked "MP-R" are most suitable.

Coating options

In addition to steel thickness, corrugation height and other parameters, the type of external coating must be taken into account when choosing. There are two main options: galvanized and painted sheets.

Zinc

In the first case, a protective zinc layer is applied to the steel sheet, which provides basic metal protection. This option is less durable than painted, but more affordable. It is suitable for temporary structures, household buildings, built in any climatic conditions.

Galvanized sheets have a silvery surface and do not heat up in the sun

Polymeric

Polymer coating is the best means of protecting metal against corrosion. Such a layer is presented in several versions, differing in durability, resistance to climatic factors, strength, and appearance. The main types of polymer coating are presented in the following options:

• polyester (PE) can be glossy or matt, and the layer thickness is 20 µm and 35 µm, respectively. The material can be operated at temperatures ranging from -30 ° to +85 ° C and has a service life of about 10 years;
• Pural is applied to steel sheets with a layer of 50 microns. Abrasion resistant, service life about 15 years. This protective layer is characterized by resistance to precipitation. It is optimal for warm regions without sudden temperature changes;
• plastisol (PVC) is applied in a layer of 200 microns, which gives the corrugated board high strength, resistance to ultraviolet radiation. Service life is about 25 years. Sheets with this coating are more expensive than those with polyester or pural protection. The coating is suitable for regions with a temperate climate, marshlands;
• polydifluorionad (PVF2) is designed for operation in the harsh climate of the North or Siberia, with sharp temperature changes and significant snow load on the roof. The coating has the highest possible strength and provides the material with a service life of over 30 years.
