Zn-Al-Mg coated steel sheet SUPERDYMA
Zinc Aluminum Magnesium Coated Steel Sheet
Better corrosion resistance than galvanized steel and galvalume
The alloy coating of ZAM steel plate is zinc (Zn) Aluminum (AI) Magnesium (mg)，which is solidified at high temperature to form a dense ternary eutectic structure, so that a dense and effective corrosion prevention super coating is formed on the surface of the steel plate.
Super corrosion resistance
Al, Mg, Si and other alloy elements are added to the ZAM steel plate coating, which greatly improves the inhibition effect of coating corrosion. Compared with ordinary galvanized products, the coating has less adhesion, but can achieve better corrosion resistance. With the same coating, the corrosion resistance of ZAM steel plate is 5-10 times that of ordinary galvanized steel plate.
Wear-resistance and easy processing
The coating of ZAM steel plate is more compact and smooth, and the surface hardness of the coating is more than twice that of ordinary galvanized steel plate, so it is not easy to be damaged in the processing process, and has excellent processing properties such as stretching, stamping, bending, welding, and excellent scratch-resistance and wear-resistance.
Wonderful self-repair
The coating components around the cutting surface of ZAM steel plate will continue to dissolve, forming a dense protective film mainly composed of zinc hydroxide, alkaline zinc chloride and magnesium hydroxide. This protective film has low conductivity and obvious inhibition effect on the corrosion of the cutting surface.
ECO-friendly protection
The surface treatment of ZAM steel plate does not contain heavy metal ions such as trivalent and hexavalent chromium, which conforms to the ROHS standard of the European Union. It is an internationally recognized environmental protection product at present. With the support of domestic policies that pay more and more attention to environmental protection and actively promote green, low-carbon and sustainable development, ZAM products are favored by more industries.
