1. Galvalume

Hot-dip 100-200g/m2 of 55% Al-Zn protective layer on the steel substrate. The corrosion resistance 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. The alkali corrosion resistance is weak; the protection period is 8-15 years.

2.Galvanized aluminum magnesium

The main component is 3%Mg-11%Al-Zn, which has strong chlorine resistance (salt/sweat/salt/sea breeze/soil) and alkali corrosion resistance, self-repairing function, and can guarantee no redness for 20-30 years rust.
