Detail Information
Introduction of Galvalume steel coil
Galvalume steel coil (GL coil) features an aluminum-zinc alloy coating (55% Al, 43.4% Zn, 1.6% Si), combining the corrosion resistance of aluminum with the cathodic protection of zinc. Fanda supplies high-quality Galvalume coils with excellent high-temperature oxidation resistance, weather durability, and formability — widely used in roofing, wall cladding, home appliances, automotive parts, and more.
