Product details
| Parameter | Specification | Unit | Remarks |
|---|---|---|---|
| Material Grade | HRB500 (High-Strength Deformed Reinforcing Bar) | — | Complies with GB 1499.2-2018 standard |
| Chemical Composition | C ≤0.25%, Si ≤0.80%, Mn ≤1.60%, P ≤0.045%, S ≤0.045%, with trace Nb, V, Ti | — | Alloying elements enhance strength and toughness |
| Diameter | 16 | mm | Standard nominal diameter for heavy-duty reinforcement |
| Weight per Meter | 1.58 | kg/m | Calculated based on 16mm diameter |
| Length Range | 6000–12000 (customizable) | mm | Standard lengths; cut-to-order available for project needs |
| Yield Strength (Minimum) | ≥500 | MPa | Key indicator of high load-bearing capacity |
| Tensile Strength | 630–830 | MPa | Typical range at room temperature |
| Elongation (δ5, Minimum) | ≥15 | % | Ensures ductility for seismic and dynamic load resistance |
| Impact Toughness | ≥34 (at 20°C) | J | Longitudinal specimens; resistance to sudden impact |
| Surface Treatment | Deformed (ribbed) | — | Ribbed design enhances concrete bonding and stress distribution |
| Weldability | Good | — | Compatible with standard welding processes for on-site fabrication |
| Corrosion Resistance | Base material: moderate; Optional: epoxy coating/galvanization | — | Enhanced options available for harsh environments (coastal, industrial) |
| Typical Applications | Heavy-duty reinforced concrete structures: high-rises, bridges, industrial plants, dams, and large-span frameworks | — | Ideal for projects requiring superior strength-to-weight ratio |
