Product details
| Parameter | HRB400 Rebar 10mm | Q235B Steel | Unit | Remarks |
|---|---|---|---|---|
| Material Grade | HRB400 (High-Strength Deformed Reinforcing Bar) | Q235B (Carbon Structural Steel) | — | Both meet Chinese national standards for construction |
| Chemical Composition | C ≤0.25%, Si ≤0.80%, Mn ≤1.60%, P ≤0.045%, S ≤0.045%, with trace Nb, V, Ti | C ≤0.20%, Si ≤0.35%, Mn ≤1.40%, P ≤0.045%, S ≤0.045% | — | HRB400 includes alloying elements for enhanced strength |
| Diameter/Section | 10 | N/A (varies by form: bars, sheets, profiles) | mm | 10mm standard diameter for rebar; Q235B available in multiple forms |
| Weight per Meter | 0.617 | N/A (varies by section/thickness) | kg/m | Calculated for 10mm rebar; Q235B weight depends on specific form |
| Length Range | 6000–12000 (customizable) | 6000–12000 (customizable) | mm | Standard lengths for construction and fabrication |
| Yield Strength (Minimum) | ≥400 | ≥235 | MPa | HRB400 provides higher load resistance for critical structures |
| Tensile Strength | 540–680 | 375–500 | MPa | Typical range at room temperature |
| Elongation (δ5, Minimum) | ≥16 | ≥26 | % | Q235B offers greater ductility for flexible applications |
| Impact Toughness | ≥34 (at 20°C) | ≥27 (at 20°C) | J | Longitudinal specimens; resistance to sudden impact loads |
| Surface Treatment | Deformed (ribbed) for concrete bonding | Mill finish, galvanized, or painted | — | HRB400 ribs ensure strong adhesion with concrete |
| Manufacturing Standard | GB 1499.2-2018 | GB/T 700-2006 | — | Compliance with Chinese structural steel regulations |
| Typical Applications | Reinforced concrete (beams, columns, slabs, bridges, foundations) | General structural components (frames, supports, brackets, light fabrication) | — | Often used together in coordinated construction systems |
