Product Description

Zinc-Aluminum-Magnesium Alloy for Strip Steel

Uses and Advantages

① Excellent corrosion resistance of the coating: its corrosion resistance is 3 to 15 times that of hot-dip galvanized steel sheet (GI), with particularly outstanding resistance to acid and alkali corrosion, resulting in a longer service life.
② Excellent corrosion resistance at the cut edge: The aluminum and magnesium elements in the coating promote the formation of a highly adherent, dense protective film at the cut edge, thereby inhibiting corrosion at this location.

③ Excellent processability: The coating hardness is higher than that of hot-dip galvanized steel sheet, offering outstanding wear resistance and scratch resistance;

④ Environmentally friendly and green product: Reducing the coating thickness while extending the product’s service life helps conserve material usage;

⑤ Wide range of applications: It can be widely used in construction, automotive, home appliances, photovoltaic mounting systems, highway guardrails, and other fields. In addition, it can be used to manufacture various steel structural components, corrosion-resistant parts, perforated panels, cable trays, and more.
