The hot-dip galvanized aluminum-magnesium steel plate is added with alloy elements such as Al, Mg and Si, which greatly improves the corrosion inhibition effect of the coating. Compared with ordinary galvanized products, the coating has less adhesion but can achieve better corrosion resistance, which is 10-20 times of that of hot-dip galvanized steel plate.

Because the corrosion resistance is 10-20 times of that of ordinary hot-dip galvanized steel plate and the corrosion resistance self-healing effect of the cut section, the service life of Leipzig color-coated steel plate made of hot-dip galvanized aluminum-magnesium alloy coated steel plate will naturally be very long, which can reach more than 15 years. 

In the process of color plate processing, the coating components around the cutting surface of hot-dip galvanized aluminum-magnesium color substrate will be continuously dissolved. The stroke is mainly composed of a dense protective film composed of zinc hydroxide, alkaline zinc oxide and magnesium hydroxide. This protective film has a low conductivity and has a inhibiting effect on the corrosion of the cutting surface.

The coating of hot-dip galvanized aluminum-magnesium steel plate is more dense than that of galvanized steel plate, so the Leipzig zinc-aluminum-magnesium color steel plate is not easy to peel off the coating during stamping, and has excellent processing properties such as stretching, stamping, bending, welding, etc. under severe conditions. Due to the high hardness of the coating and the strong adhesion of the coating high-temperature paint, it has excellent damage resistance.
