galvanized steel plate
Looking for cost-effective galvanized steel plates with reliable corrosion resistance? You've found the right source. As a direct factory with 20 years of structural steel experience, GNEE Steel supplies high-quality S350GD+Z120 galvanized steel plate that meets EN 10346 standards at factory prices. In this guide, we'll explain its key features, 2026 pricing, and total landing cost calculation.
Galvanized steel plate
Galvanized steel is steel coated with zinc to prevent rust and extend service life. The zinc layer acts as a protective barrier against moisture and oxygen.
It's widely used in construction, automotive parts, home appliances, and agricultural equipment. Common galvanized steel grades include S250GD, S350GD, and S450GD.
S350GD+Z120 refers to S350GD-grade steel with Z120 zinc coating (120g/m²), balancing protection and affordability for moderate environments.
Chemical Composition of S350GD+Z120 Galvanized Steel Plate
The chemical makeup of S350GD+Z120 ensures its structural stability and processability. Below is the standard composition:
| Element | Maximum Content (%) |
|---|---|
| Carbon (C) | 0.12 |
| Silicon (Si) | 0.50 |
| Manganese (Mn) | 1.60 |
| Phosphorus (P) | 0.035 |
| Sulfur (S) | 0.035 |
| Aluminum (Al) | 0.020 |
| Titanium (Ti) | 0.22 |
This composition guarantees compatibility with bending, cutting, and welding processes.
Mechanical Properties of S350GD+Z120 Galvanized Steel Plate
S350GD+Z120 delivers excellent mechanical performance for structural applications. Key properties are shown below:
| Mechanical Property | Standard Value |
|---|---|
| Yield Strength | ≥350 MPa |
| Tensile Strength | 420-560 MPa |
| Elongation (A80mm) | ≥18% |
| Bending Capacity | D=2t, 180° without cracking |
| Zinc Coating Weight | 120g/m² (minimum) |
The Z120 coating provides sufficient corrosion resistance for indoor and mild outdoor use.
