Looking for high-quality galvanized steel coil for your project? You've come to the right place. As a direct factory with over 15 years of experience, GNEE Steel supplies EN 10346-compliant galvanized steel coil in popular grades like DX51D, S320GD, and S350GD at factory prices. In this guide, we'll detail grades, technical specs, and 2026 pricing to help you make cost-effective choices.
Galvanized steel coil
Galvanized steel coil is a rolled steel product coated with zinc to resist corrosion, widely used in construction, automotive, and home appliances. Common grades range from general-use (DX51D) to high-strength (S350GD), each tailored to specific load and environment needs-choosing the right grade avoids overspending or performance issues.
Whether you need light-duty coil for appliance shells or heavy-duty options for structural beams, our galvanized steel coil meets international standards and delivers consistent quality.
Key Grades of GNEE Steel's Galvanized Steel Coil
We offer a full range of galvanized steel coil grades to match diverse applications. The table below details their core properties and uses:
| Grade | Yield Strength (Min) | Tensile Strength Range | Elongation (%) | Typical Application |
|---|---|---|---|---|
| DX51D | 235 MPa | 315-500 MPa | ≥28 | Home appliance shells, light cladding |
| S280GD | 280 MPa | 370-510 MPa | ≥22 | Roof purlins, light structural parts |
| S320GD | 320 MPa | 370-500 MPa | ≥18 | Medium-load beams, automotive components |
| S350GD | 350 MPa | 410-550 MPa | ≥17 | Heavy structural beams, truck chassis |

Chemical Composition (DX51D vs. S350GD)
| Element | DX51D (%) | S350GD (%) | Role |
|---|---|---|---|
| C | ≤0.12 | ≤0.12 | Ensures strength without brittleness |
| Mn | ≤0.60 | ≤1.60 | Boosts tensile strength (higher in S350GD) |
| P | ≤0.045 | ≤0.035 | Minimized to avoid cold cracking |
| S | ≤0.045 | ≤0.030 | Reduced to improve weldability |
