Zinc Aluminum-Magnesium Coated Steel Sheets & Coils

Zinc Aluminum-Magnesium Coated Steel Sheets & Coils

Zinc Aluminum-Magnesium Coated Steel is a new type of corrosion-resistant coated steel sheet that adds Al, Mg, Si to the conventional Zn plating. Si improves the corrosion resistance of the coating layer containing Al while further improving the corrosion effect by the combination with Mg. This Zinc Aluminium Magnesium steel results in superior corrosion-resistance on the surface, bend processed parts, ammonia environment, cut edge, and drawn parts.

The rust resistance of the end face is also excellent, and alkali resistance is also excellent.

In comparison with hot-dip galvanized steel and hot-dip galvanized 5% aluminum alloy steel, zinc aluminum magnesium steel can achieve the same corrosion resistance using fewer plating layers.  In many cases, it can substitute for stainless steel or aluminum plate.

Weldability and paintability are very good. In addition, the coating hardness is high, with excellent resistance to damage. In Comparison of Corrosion Resistance With Galvanized Steel (GI (H)) and Galvalume (Galvalume)

The corrosion resistance of this zinc aluminum magnesium alloy coated steel sheet is 5 to 10 times higher than that of the hot-dip galvanized steel sheet, and is also better than galvalume steel.

Zinc Aluminum-Magnesium Coated Steel Sheets & Coils can be used in construction, road protection, storage equipment, and automotive parts. Switching to zinc aluminum magnesium coil will eliminate post-galvanizing and post-painting processes.
