2.  Galvalume steel coil



The surface of the galvanized steel sheet presents a unique smooth, flat and gorgeous star flower, and the base color is silver-white. The special coating structure makes it have excellent corrosion resistance. The normal service life of the aluminum-zinc plate can reach 25a, and it has good heat resistance and can be used in a high temperature environment of 315°C; the adhesion of the coating and the paint film is good, and it has good processing properties, and can be punched, cut, welded, etc.; The surface conductivity is very good.
The coating composition is composed of 55% aluminum, 43.4% zinc, and 1.6% silicon in weight ratio. The production process of galvanized steel sheet is similar to that of galvanized steel sheet and aluminized sheet, which is a continuous molten coating process. The galvanized steel sheet with 55% aluminum-zinc alloy coating has better corrosion resistance than galvanized steel sheet of the same thickness when exposed to the same environment on both sides. The aluminum-zinc-plated steel sheet with 55% aluminum-zinc alloy coating not only has good corrosion resistance, but also the color-coated products have excellent adhesion and flexibility.
