- Corrosion resistance
Al, Mg, Si and other alloying elements are added to the zinc-aluminum-magnesium steel plate coating, which greatly improves the corrosion resistance and inhibition effect, which is 10 to 20 times that of the hot-dip zinc Hong Kong version.
- Self-healing
The coating components around the cutting surface 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 has an inhibitory effect on the corrosion of the cutting surface.
- Long life
Due to the super corrosion resistance and the self-healing effect of the cut section, the service life of components made of zinc, aluminum and magnesium is very long. Under normal circumstances, it can reach more than 30 years.
- Easy to process
The coating of zinc-aluminum-magnesium steel plate is denser than that of galvanized plate, so it is less likely to produce coated glass during stamping processing. It has excellent processing properties such as stretching, stamping, bending, and welding under severe conditions, and due to the relatively high hardness of the coating High, thus providing excellent damage resistance.
