Zinc-aluminium-magnesium Sheet

- Superior corrosion resistance

Al, Mg and Si alloy elements are added to the zinc-aluminium-magnesium steel coating, which greatly improves the corrosion inhibition effect of the coating, and achieves superior corrosion resistance with less coating adhesion than ordinary galvanised products, which is 10 to 20 times higher than that of hot-dip galvanised steel sheets.

- Self-healing

Zinc, aluminium and magnesium products processing incision self-repair refers to the incision surface in the humid corrosive environment, the plating material near the incision by dissolving into the exposed metal surface attached to the water film, constantly migrate to the exposed incision position, the formation of zinc hydroxide, alkaline zinc chloride and magnesium hydroxide and other components of the dense protective film (white rust), and gradually covered with the exposed incision of the metal, the outside world of corrosive media and the exposed metal substrate isolation, so as to Prevent further corrosion of the bare incision. The whole process will continue for a long time.

- Long Life

Zinc-Aluminium-Magnesium with Mg-Al-Zn as the key component has a strong and reliable resistance to chlorine (salt/sweat/sea/evening wind/soil layer) and alkali corrosion, which ensures that red rust does not occur for 20-30 years.

It is an excellent all-round plating product, which is 10-20 times stronger than galvanising with the same amount of plating, has excellent protection of the cut-outs, and has good weldability.
