Hot-dipped Galvalume Steel Sheets(GL) is made by coating cold-rolled steel with a layer of aluminum-iron-zinc-silicon coating. Compare to galvanized steel, galvalume steel has an even better corrosion resistance, heat resistance, and heat reflectivity. It is also more decorative, benefited from the Al-Zn alloy crystal pattern on the surface of the coating.
Galvalume is a relatively new technology compared to galvanizing, and it is getting increasingly popular because of its great performance, affordability, and ornamental effect.
