Product Description

What is Zinc Aluminum Magnesium Steel Coil?

Zinc Aluminum Magnesium Steel Coil (Zn-Al-Mg steel coil) is a new type of corrosion-resistant steel, produced by coating the surface with a special alloy containing zinc, aluminum, and magnesium. This advanced coating technology provides outstanding anti-rust properties, excellent formability, and long-lasting durability, making it an ideal alternative to traditional galvanized steel coils.

Compared to conventional galvanized (GI) steel coils and galvalume (GL) steel coils, Zn-Al-Mg steel coils deliver significantly better performance in coastal, industrial, and humid environments.
