High density zinc-aluminum-magnesium coil

High density zinc-aluminum-magnesium coilThe coating of Zinc-aluminum-magnesium steel plate (ZAM) is made of zinc (Zn), aluminum (AI), magnesium (Mg) after continuous high temperature dry solidification to produce a tight ternary carbide structure, so that the surface of the steel plate produces a layer of high-density, effective prevention of corrosion super coating. 1. Strong corrosion resistance: zinc aluminum magnesium steel plate coating added Al, Mg and Si alloy components, further improve the coating corrosion control effect, compared with the general galvanized products, the coating adhesion amount is less but can achieve better corrosion resistance, under the same coating premise, zinc aluminum magnesium steel plate corrosion resistance is the general hot-dip galvanized steel plate 5 to 10 times. 2. Wonderful self-healing: the coating composition around the cutting surface of zinc aluminum magnesium steel plate is also constantly mixed, which is mainly composed of zinc hydroxi…
