Nowadays, when carrying out construction work, new materials are increasingly being used, abandoning the old ones. One of these "novelties" is corrugated board (profiled metal sheet, which has a number of advantages over other roofing materials: strength, ease of installation, durability, lightness, and external attractiveness. The base of the corrugated sheet is a metal sheet. To increase the level of rigidity, it is run through a specially designed die. After that, triangular, rectangular or wave-shaped edges are formed on the surface of the sheet. In order to increase the resistance of the metal to corrosion, steel is treated by hot-dip galvanizing. A profile sheet is used as a roofing material, for exterior wall decoration, and for mounting fences. Due to the fact that the material is very light, it has a profiled surface, so it is easy to assemble a variety of coatings from it without using heavy machinery.The polymer coating enhances the aesthetic qualities of this material and its service life. As a result, a roof or fence can last at least 50 years. The cost of colored corrugated sheet is the same as that of galvanized material. Different polymers are used to cover the sheets. The most common are plastisol, polyester, and pural. The first one is called the most resistant to ultraviolet radiation, so it is used for roofing. This material will not burn out in the sun and will delight the owners with its color for a long time. Plastisol is highly resistant to corrosion, but it is not very resistant to sunlight. Because of this, it is rarely used in the southern regions. Before purchasing corrugated board, it is advisable to determine its type. To do this, you need to look at its appearance and product labeling. The profiled sheet is used for roofing work. It has excellent characteristics, has strong and high ribs, which are marked with the symbol "H" and with a height of more than 44 millimeters. For partitions, corrugated board is used with trapezoidal ribs with dimensions from 8 to 44 millimeters, such material is marked with the symbol "C". There is also a corrugated board that is suitable for both roofs and fences. The size of such a material is 35-44 millimeters, its marking is "CH". It should also be remembered that if the corrugated board needs to be cut off during installation, then it is recommended to cover the exposed metal surface with an anti-corrosion agent or a good polymer dye first. Platform accessibility is a major asset, with dedicated applications for both Android and iOS devices.
