Hot Dip Galvanized Aluminum Magnesium / Zn-Al-Mg Steel Coil ZAM80-120g/㎡

Galvanized aluminum magnesium steel Coil (Zn-Al-Mg ) is a new type of high corrosion resistance coating steel material, its coating composition is mainly zinc, by zinc plus 1.5%-11% aluminum, 1.5%-3% magnesium and trace silicon composition (different manufacturers slightly different proportions), mainly used as steel and steel products surface anti-corrosion treatment, including a variety of zinc series of coating and a large number of steel parts of the whole dip plating anti-corrosion.

Product Features Of Zn-Al-Mg :

(1) High corrosion resistance: The magnesium (Mg) component of the coating is conducive to promoting the formation of a very stable and dense protective film, generating and maintaining a film-like covering layer on the surface of the coating, thereby exerting excellent corrosion resistance.

(2) Incision protection: The incision parts of the steel plate processing are exposed to the air and are prone to red rust corrosion. However, the alloy elements in the surface coating of zinc, aluminum and magnesium form water-soluble ions in the atmospheric corrosion environment, and gradually cover the incision with the flow of liquid film, forming a stable protective film and covering the red rust at the incision position, significantly improving the corrosion resistance of the incision.

(3) Easy stamping: The reciprocating friction test machine is used to evaluate the friction behavior of zinc aluminum magnesium coating (ZM) and pure zinc coating (GI) in the process of multiple friction. The friction coefficient of zinc-aluminum-magnesium coating is 15% lower than that of pure zinc coating, and it remains stable during the reciprocating friction process, indicating that zinc-aluminum-magnesium coating has excellent wear resistance.

Comparison of salt spray test

Corrosion resistance of Zn-Al-Mg coating steel is significantly better than that GI.

The thickness of the galvanized coating can vary depending on the application and customer requirements. Standard thicknesses range from 0.3mm to 2.0mm, with widths typically ranging from 550mm to 2080mm. The steel coil can also be further processed, such as being cut into sheets or formed into specific shapes, to meet specific customer needs.
