Professional flooring of the n-75 brand - the sizes,

Roofing masters, builders know how versatile profiled. Profiled steel sheets with high bearing capacity, durability, corrosion resistance, are used to perform most construction operations, including the creation of prefabricated structures, roof overlap, wall cladding or ceiling. In this article we will describe in detail about the self-supporting professional flooring H-75, its characteristics, as well as methods of use in roofing works.

Production technology

Profiled sheeting H75 is a practical, durable material that has a fairly light weight with a high carrying capacity. It is produced on special lines from blanks, which are sheets of high-quality sheet steel grade 220 according to GOST R 52246-2004 and GOST R 52146-2003, depending on the type of protective and decorative coating. In the production process, this material goes through the following stages:

1. Cold hire. Steel blanks are rolled into sheets with a thickness of about 0.7-0.9 mm, which will later be given a relief.
2. Pressing. With the help of large industrial presses and special forms, galvanized steel sheet is made wavy.
3. Drawing a protective and decorative covering. Paint or polymeric coating is applied on the profiled steel sheets, which improves the decorative properties of the material, as well as additionally protects against corrosion.
4. Cutting to size. Then the professional flooring is cut on sheets of the standard size or by the sizes of the customer.

Please note that when cutting professional grade H75 cut sizes may vary, since there is a production opportunity to produce material with a length of 1-13 m with a cutting step of 1 meter.

Properties

Professional flooring H75 - a practical and reliable material that is used to produce a variety of construction operations. It belongs to the self-supporting brands, since, due to the additional stiffening ribs, it can easily withstand considerable static and dynamic loads. The material of this brand has the following useful properties:

• Lightweight enough. Low weight with high bearing capacity and strength allows using this material for the construction of the roof without excessively weighting the structure.
• Reinforced profile. The galvanized professional sheet of this brand is enhanced by additional protrusions on the horizontal and vertical surfaces of the trapezoidal profile.
• Universal purpose. The professional sheet brand N-75 can be used to overlap the roof, building fences or fences, covering walls and ceilings.
• High corrosion resistance. Steel with a protective coating of zinc, deposited according to GOST, does not oxidize well under the influence of water, so this material lasts much longer.

Important! Not only affordable price and relatively light weight make developers use H75 professional flooring for overlapping. In addition to other useful qualities of this material due to the profile height of 7.5 cm, well drains water from the surface of the slope, as well as fit on the permitted crate.

Specifications

Technical characteristics of the professional flooring H75 allow to call it a universal material. The professional sheet made according to GOST has a long service life and carrying capacity, therefore it is used in many areas of construction. It has the following properties:

1. The useful width of the material is 750 mm.
2. The wave height is 75 mm, the trapezoidal profile, of complex shape with additional stiffeners on the vertical and horizontal surfaces.
3. The weight of 1 square meter of material is 9.8-12.5 kg, depending on the thickness of the workpiece.
4. The thickness of the workpiece is 0.7-0.9 mm.
5. The length of the sheet is 1-13 m, depending on the size of the cut.

Consider that due to the high profile height and additional stiffeners, the useful width of the material decreases, therefore, taking into account the overlap per 1 wave, the flow rate is quite large and uneconomical.

Ways to use

Self-supporting sheeting H75, manufactured according to the requirements of GOST, has high strength properties, corrosion resistance and good bearing capacity. It is used in construction for the following tasks:

• The construction of prefabricated structures made of profiled steel sheet independently and as part of sandwich panels.
• For roofing. In this case, if the slope of the slope is 6-8 degrees, the distance between the truss legs, which is laying, can be 4 m.
• The construction of fences and fences, which, thanks to the double-sided protective-decorative coating, look equally attractive on both sides.

Important! When choosing a professional sheet, it is imperative to pay attention to the quality of the material, to detect the presence of chips and scratches that spoil the protective coating. In case of any doubt, it is better to give preference to products of another manufacturer.
