S320GD galvanized steel

S320GD galvanized steel
Need reliable S320GD galvanized steel sheets for structural projects that demand both strength and corrosion resistance? Unlike generic suppliers, GNEE focuses on structural-grade galvanized products with project-specific customization.
We can produce S320GD+Z160 galvanized steel sheets in tailored thickness (1.0-12.0mm for structural use), width (up to 3000mm), and cut-to-length sizes-matching your blueprints and load requirements.
Read on to learn how S320GD+Z160 galvanized steel sheets enhance structural performance, and our quality assurance for critical infrastructure projects.
Galvanized steel sheets are carbon steel panels coated with zinc to prevent rust, essential for structural applications exposed to weather.
Common structural uses include roofing frameworks, wall supports, and temporary structures. S320GD galvanized steel is a high-strength structural grade-with the Z160 coating (160g/m² zinc per side) delivering long-term protection for outdoor and high-humidity environments.
Chemical Composition of S320GD+Z160 for Structural Use
The chemical composition of S320GD+Z160 galvanized steel sheets is engineered to meet structural load and durability requirements:
| Element | Symbol | Content (Max. %) | Role in Structural Performance |
|---|---|---|---|
| Carbon | C | 0.12 | Balances strength and weldability for joints |
| Manganese | Mn | 1.60 | Enhances load-bearing capacity without brittleness |
| Phosphorus | P | 0.035 | Minimized to prevent cracking under structural stress |
| Sulfur | S | 0.030 | Reduced to avoid weak points in load-bearing areas |
| Silicon | Si | 0.50 | Improves zinc coating adhesion for long-term protection |
| Titanium | Ti | 0.22 | Refines grain structure for consistent load distribution |
| Niobium | Nb | 0.09 | Enhances creep resistance under sustained loads |
Mechanical Properties of S320GD+Z160 Structural Steel Sheets
S320GD+Z160 galvanized steel sheets deliver the mechanical performance required for structural safety, as shown below:
| Property | Standard | Value | Structural Significance |
|---|---|---|---|
| Yield Strength (Min.) | MPa | 320 | Resists permanent deformation under design loads |
| Tensile Strength | MPa | 400-510 | Withstands peak loads during construction/use |
| Elongation (Min.) | % | 22 | Allows minor flexing without breaking |
| Bending Strength | MPa | ≥380 | Handles stress from structural deflection |
| Impact Energy (0°C) | J | ≥27 | Resists sudden load changes (e.g., wind, snow) |
| Zinc Coating Hardness | HV | ≥80 | Prevents coating damage during installation |
Size Specifications of S320GD+Z160 Structural Sheets
GNEE provides S320GD+Z160 galvanized steel sheets in sizes optimized for structural applications:
| Sheet Type | Thickness Range | Width Range | Length Range | Typical Structural Applications |
|---|---|---|---|---|
| Standard Sheets | 1.0-6.0mm | 1000-2000mm | 2000-6000mm | Roof purlins, wall studs |
| Heavy-Duty Sheets | 6.0-12.0mm | 1200-3000mm | 3000-12000mm | Floor joists, support beams |
| Custom-Cut Sheets | 1.5-10.0mm | Custom (per blueprint) | Custom (per blueprint) | Specialized structural components |
All sheets meet structural tolerance standards (±0.05mm thickness, ±2mm length/width) for precise assembly.
Key Structural Applications of S320GD+Z160 Galvanized Sheets
S320GD+Z160 galvanized steel sheets excel in various structural scenarios due to their balanced properties:
- Roofing Frameworks: The Z160 coating resists rain and UV damage, while 320MPa yield strength supports snow loads.
- Wall Cladding Supports: Formability allows bending for custom profiles, with corrosion resistance for exterior use.
- Temporary Structures: Lightweight yet strong, ideal for construction site offices and storage facilities.
- Agricultural Buildings: Withstands farm chemicals and humidity, requiring minimal maintenance.
- Industrial Warehouses: Handles heavy ceiling loads while resisting interior moisture and chemical exposure.
S320GD galvanized steel sheets with Z160 coating are a reliable choice for structural applications, combining high strength, corrosion resistance, and formability.
Their consistent mechanical properties and durable zinc coating ensure long-term structural safety and reduced maintenance costs.
