Zinc coating weight (also called zinc mass) is measured in g/m² (both sides total). It determines the corrosion resistance lifespan of the steel.
| Grade | Coating Mass (g/m²) | Typical Application |
|---|---|---|
| Z40-Z80 | 40-80 | Indoor use, light protection |
| Z100-Z140 | 100-140 | General construction, roofing |
| Z180-Z275 | 180-275 | Heavy industry, structural components |
| Z350-Z450 | 350-450 | Coastal areas, high-corrosion environments |
Note: Higher coating weight = longer service life = higher cost. We recommend selecting based on your actual environmental conditions.
Our galvanized steel coils comply with major international standards:
All products come with Mill Test Certificates (MTC) that can be provided upon shipment.
Spangle refers to the visible crystal patterns on the surface of galvanized steel, formed during the solidification of the zinc coating.
| Type | Description | Best For |
|---|---|---|
| Regular Spangle | Visible snowflake-like crystals | Applications where appearance is not critical; prepainted base |
| Zero Spangle (Minimal Spangle) | Smooth, uniform surface with no visible crystals | Painting applications, prepainted steel, automotive parts, where surface smoothness matters |
Recommendation: If you plan to paint directly on the surface, zero spangle is strongly recommended for better paint adhesion.
While galvanized steel offers excellent corrosion protection, white rust (zinc oxide) can occur under certain conditions:
