55% Alu-Zinc Coated Steel Coil/ Gl galvalume steel sheet is composed of aluminum-zinc alloy structure, which is composed of 55% aluminum, 43.5% zinc and 1.5% silicon solidified at a high temperature of 600°C. Its entire structure is composed of aluminum-iron-silicon-zinc, forming a dense quaternary crystal An alloy .The corrosion resistance of "aluminized zinc steel coil" is mainly due to the protective function of aluminum and aluminum. When zinc is worn, aluminum forms a dense layer of aluminum oxide, which prevents corrosion-resistant substances from further corroding the interior.

55%alu GL COILS Aluminum-zinc alloy steel plate has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. It is very similar to the high temperature oxidation resistance of aluminum-plated steel plate. It is often used in
Chimney tube, oven, luminaire and fluorescent lampshade.The heat reflectivity of galvalume aluzinc alloy steel sheet is very high, which is twice that of galvanized steel sheet. People often use it as a material for heat insulation.
