Roof decking – a group of profiled sheet steel material that can withstand much more significant loads than sheets of corrugated wall. At the height of the roof sheeting profiles are not should be less than 20mm, it is through profiles (trapezoidal shape or a wave), the material receives the necessary level of rigidity. The name defines the basic scope of the corrugated board – an organization of roofing. Roof decking is used for flat or pitched roofs, with small buildings and based on steel, and large industrial facilities. Stiffness of the material does not give it to sag over the life use. The group of roof sheeting include profnasil with markings C21, C44, NS35, P35, MP20, N60.
The height of the corrugation (profiles) – more than 20 mm. Besides them, give additional rigidity ribs available, along crimp on them. Stiffeners can significantly increase the mechanical load on the roof decking. As a roofing material, corrugated board should provide not only strength but also a reliable waterproofing. Roofing performed with the use of profiled steel sheets to meet these requirements. Firstly, the protection of steel sheet attached to the zinc layer. Second, the polymer coating. On the polymer coatings should be discussed separately.
They are made of modern types of polymers, steel sheet protected on both sides of corrosion, scratches and damages of any kind. Polyester cover most economical, but are sufficiently reliable. It can be shiny or matte, color options set. Coverage of the Puranas – the most durable, it is difficult to scratch even on purpose. It is better than all the other fuses the steel from rusting, so roofing materials with puralovym coating are recommended for areas with a wet rainy climate. Plastizolovye coverage – the most decorative, their surface can be expressed by the structure. In addition, plastisol – the most durable. Application various polymer coatings for roofing decks increases its service life to 50-55 years or more. But the so-called roof decking – is not only reliable and inexpensive device roofs. The material used in all areas of industrial construction. From it quickly and efficiently assemble the walls of workshops, small pavilions completely different sheds, sheds, fences – both temporary and long-term facilities. High reliability, durability and high quality corrugated roofing made of Application economically viable in many different areas.
