Color Coated Corrugated Steel Sheet for Roof

 ASTM 4118 Galvanized Corrugated Steel Sheet, also known as Seamless Galvanized Sheet or Tin Sheet, 0.25 to 2.5 mm thick. Corrugated steel plate is a structural material that corrugates a certain size of plate steel (SS400, SS490, SS590, etc.) to increase the structural rigidity. The use of hot-dip galvanizing (double-sided 900g/㎡) can guarantee the design durability of more than 50~100 years. It has the characteristics of light weight, high strength, rich luster, convenient construction, earthquake resistance, fire resistance, waterproof, long service life and maintenance-free, and has been widely used. The surface of the steel plate is beautiful, with block or leaf zinc particles, and the galvanized layer is firm and resistant to atmospheric corrosion. At the same time, the steel plate has good welding performance and cold forming performance. Compared with electro-galvanized steel sheets, hot-dip galvanized steel sheets have thicker galvanized layers and are mainly use…
