| Elongation (A80mm) | ≥20% (t≤3mm) | ≥22% (t≤3mm) | EN ISO 6892-1 |
| Bend Test (180°) | D=2t, No Cracks | D=2t, No Cracks | EN ISO 7438 |
The actual performance of our products exceeds the standard requirements, providing an extra safety guarantee for overseas projects that face complex environmental conditions.
Zinc Coating Specifications and Corrosion Resistance
The zinc coating of S350GD galvanized steel is the key to its corrosion resistance. GNEE STEEL offers multiple zinc coating options to adapt to different overseas project environments:
| Zinc Coating Type | Zinc Coating Weight (g/㎡) | Corrosion Resistance (Salt Spray Test) | Suitable Environment |
|---|---|---|---|
| Z60 | ≥60 | ≥240 hours (no red rust) | Dry inland areas |
| Z140 | ≥140 | ≥480 hours (no red rust) | Humid inland areas |
| Z275 | ≥275 | ≥720 hours (no red rust) | Coastal areas, high-humidity regions |
For overseas projects in coastal or tropical areas with high humidity, we recommend choosing Z275 zinc coating to ensure the service life of the steel structure exceeds 20 years.
