Galvalume Steel Strip

Galvalume steel is also called Aluminum-Zinc Alloy Coated Steel, Zincalume steel, aluminized zinc steel (aluzinc steel), SGLC, The galvalume metal is composed of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at 600 ~C. Its whole structure consists of aluminium-iron-silicon-zinc, forming a compact quaternary crystal alloy. The surface of the galvalume steel sheet is characterized by smooth, flat and gorgeous stars, and its base color is silver white. The special coating structure makes it have excellent corrosion resistance.

Aluminum zinc alloy steel plate has good heat resistance, can withstand high temperature of more than 300 degrees Celsius, similar to the high temperature oxidation resistance of aluminum plated steel plate, it is often used in chimney tube, oven, illuminator and fluorescent lamp shade. The thermal reflectance of Al Zn steel sheet is very high, which is twice as high as that of galvanized steel sheet. Because the density of 55% Al Zn is smaller than that of Zn, the area of Al Zn steel sheet is more than 3% larger than that of galvanized steel sheet with the same weight and thickness of gold plating layer.
