Excellent Performance
Note: Red rust occurs after 400 hours of Galvalume Steel, and rapidly after 1000 hours of Galvanized coil. After 1200 hours of Zinc Aluminum Magnesium Coil, there is no red rust and the condition is good.
5. Acid and alkali resistance: Compared to galvalume steel, zinc aluminum magnesium coil has less reduction in coating in acidic and alkaline environments. Galvanized coil has poor chemical resistance in strong acids with a pH value of 1-2, while aluminum zinc plating has poor chemical resistance in strong alkali with a pH value of 13-14, but zinc aluminum magnesium coil has better chemical resistance. Can be used for agriculture, animal husbandry, building materials, etc.
6. Environmental protection: It does not contain environmentally harmful Cr6+and uses Cr3+to achieve corrosion resistance. It is a very environmentally friendly material that meets the RoHS standards of the European Union and is internationally recognized as an environmental-friendly high-quality product.
7. Cost-effective: Performance meets or exceeds stainless steel standards in multiple aspects, but the price is far lower than stainless steel.
8. Various applications: Suitable for industrial construction, agriculture, animal husbandry construction, railway roads and bridges, power communication facilities, photovoltaic brackets, industrial facilities, and many other fields.
