Hot dipped galvalume steel coils

Short Description:

Product Detail

Product Tags

Product name  Hot dipped galvalume steel coils
Aluzinc coating  30-150 g/m2
Material  cold steel coils
Thickness  0.16mm-2.0mm
Width  750mm-1250mm


The surface of the galvalume 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 stamped, 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 55% aluminum-zinc alloy-coated galvanized steel sheet has better corrosion resistance than the galvanized steel sheet of the same thickness when exposed to the same environment on both sides. 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.

According to the data, the comprehensive anti-corrosion ability of 55% aluminum-zinc plating is 4 times that of galvanizing with the same thickness.


1. The waterproof paper inside cover the steel coils
