1. product feature and applications:
GL corrugated roofing sheets 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
Constructions building roofing sheets panels etc. 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.
