Prepainted steel is also called color coated steel. It is based on metal coils (cold-rolled, hot-dip galvanized/galvalume, aluminized and stainless steel) It is made by coating or laminating various organic coatings or plastic films on the surface. According to different application fields, it can be categorized into PPGI, PPGL, home appliance, self-cleaning, printed steel and prepainted aluminium steel
The coating composition is composed of 55% aluminum, 43.5% zinc, and 1.5% silicon.
The production process of galvanized steel is similar to that of galvanized steel, which is a continuous molten coating process.
The galvalume steel has better corrosion resistance than galvanized steel of the same thickness when exposed to the same environment.
The galvalume steel not only has good corrosion resistance, but also excellent adhesion and flexibility with color coated products
Corrugated steel sheet is processed to various waves by rolling and bending. It is widely used in architecture, storage, warehouse, building wall and intrinsic & extrinsic decoration.
Having characteristic of light weight, high strength, rich color, convenient and quick construction, earthquake resistance, fire prevention, rainproof, maintenance-free
