The basic introduction of the galvalume steel

The surface of galvalume steel is characterized by smooth, flat and gorgeous star flowers, and the base color is silver white. The special coating structure makes it have excellent corrosion resistance. The normal service life of galvalume steel can reach 25A, with good heat resistance. It can be used in high temperature environment of 315 ℃; The adhesion between coating and paint film is good, with good processing performance, and can be used for stamping, shearing, welding, etc; The surface conductivity is very good.

The coating of the galvalume steel consists of 55% aluminum, 43.4% zinc and 1.6% silicon by weight. The production process of galvalume steel is similar to that of galvanized steel plate and aluminized plate, which is a continuous molten coating process. When both sides are exposed to the same environment, the aluminum zinc plated steel plate with 55% aluminum zinc alloy coating has better corrosion resistance than the galvanized steel plate with the same thickness. The 55% aluminum zinc alloy coated aluminum zinc steel plate not only has good corrosion resistance, but also the color coated products have excellent adhesion and flexibility.
