Features of Aluminium-Zinc
The corrosion protection layer must be added on the surface because the steel plate will be oxidized and corroded by damp. The corrosion protection coating is generally divided into hot-dip galvanized zinc and hot-dip aluminum-zinc alloy Al-Zn(aluminum-zinc alloy composition is 53% of aluminum, 43.5% of zinc and 1.5% of silicon, referred to as 55%Al-Zn).The data show that the comprehensive anticorrosion ability of 55% aluminum-zinc plating is 4 times that of zinc plating of the same thickness.
