Mechanical Properties & Coating Adhesion
| Steel Grade | Yield Strength (MPa) ≥ | Tensile Strength (MPa) ≥ | Elongation (%) ≥ | Bending Test |
|---|---|---|---|---|
| S320GD+Z, S320GD+ZF | 320 | 390 | 15 (L0=80mm, b=20mm) | 3a (≤0.7mm), 4a (>1.5mm) |
Coating Weight Specifications
| Coating Form | Surface Structure | Zinc Coating (g/m²) | Zn-Fe Alloy Coating (g/m²) |
|---|---|---|---|
| Equally Coating | Z, X, G, GX, N, R | 40/40 to 225/225 | 30/30 to 90/90 |
| Differential Coating | N, R | 30 to 150 (each side) | - |
Note: 50 g/m² coating weight equals approximately 7.1µm. Maximum differential coating thickness ratio is 1:3.
