Classification of Zn-Al-Mg Products by Aluminum Content
Based on the aluminum content in the coating, Zn-Al-Mg products can be classified into the following three categories:
| Type | Aluminum Content | Main Characteristics |
|---|---|---|
| Low-Aluminum Zn-Al-Mg | 1%-3.5% | Upgraded corrosion resistance version of hot-dip galvanized coating; mainstream product in China |
| Medium-Aluminum Zn-Al-Mg | 5%-11% | Balanced corrosion resistance and workability; e.g., Shougang’s medium-Al Zn-Al-Mg products |
| High-Aluminum Zn-Al-Mg | Approx. 55% | Upgraded corrosion resistance version of hot-dip galvalume coating |
