Zinc Aluminum Magnesium (Zn-Al-Mg) Steel Coil is a new generation of high corrosion-resistant coated steel product, manufactured by adding appropriate amounts of aluminum (Al) and magnesium (Mg) alloying elements to the traditional hot-dip galvanizing bath
Product Classification
| Type | Aluminum Content | Main Characteristics |
| Low-Al Zn-Al-Mg | 1%-3.5% | Upgraded corrosion resistance from hot-dip galvanizing |
| Medium-Al Zn-Al-Mg | 5%-11% | Balanced corrosion resistance and workability, e.g., Zn-11%Al-3%Mg |
| High-Al Zn-Al-Mg | ~55% | Upgraded corrosion resistance from hot-dip galvalume |
