|---|---|---|
| Product Name | Rebar for Residential Building Projects | Deformed steel reinforcing bar used in concrete structures of residential buildings |
| Material Grade | HRB400 / HRB500 (GB); Grade 60 (ASTM A615); B500B (EN 10080) | High-strength deformed reinforcing steel; international equivalents ensure global applicability |
| Standard Compliance | GB/T 1499.2, ASTM A615/A615M, EN 10080, JIS G3112 | Meets major international standards for structural reinforcement in residential construction |
| Chemical Composition – Carbon (C) | ≤ 0.25% | Controls hardness and weldability; low carbon content improves ductility |
| Chemical Composition – Manganese (Mn) | ≤ 1.60% | Enhances tensile strength and hardenability of the steel |
| Chemical Composition – Phosphorus (P) | ≤ 0.045% | Strictly limited to prevent cold brittleness and reduce cracking risk |
| Chemical Composition – Sulfur (S) | ≤ 0.045% | Controlled to avoid hot shortness and improve toughness |
| Chemical Composition – Silicon (Si) | ≤ 0.80% | Improves strength and deoxidation during steelmaking |
| Tensile Strength | ≥ 540 MPa (HRB400); ≥ 630 MPa (HRB500); ≥ 620 MPa (Grade 60) | Minimum tensile strength per GB/T 1499.2 and ASTM A615; ensures structural load-bearing capacity |
| Yield Strength | ≥ 400 MPa (HRB400); ≥ 500 MPa (HRB500); ≥ 420 MPa (Grade 60) | Minimum yield strength guaranteeing resistance to permanent deformation under design loads |
| Elongation | ≥ 16% (HRB400); ≥ 15% (HRB500); ≥ 9% (Grade 60) | Minimum elongation at fracture; ensures ductility for seismic and dynamic load performance |
| Diameter Range | 6 mm – 50 mm | Common diameters: 6, 8, 10, 12, 14, 16, 18, 20, 22, 25, 28, 32, 36, 40, 50 mm |
| Length | 6 m, 9 m, 12 m (standard); custom lengths available | Standard mill lengths; cut-to-length service available upon request |
| Surface Finish | Hot-rolled deformed (ribbed) surface | Transverse and longitudinal ribs improve mechanical bond with concrete per design requirements |
| Application | Foundations, columns, beams, slabs, shear walls in residential buildings | Suitable for low-rise to high-rise residential structures; compatible with seismic design zones |
| Certification | ISO 9001, CE Marking, Mill Test Certificate (MTC) per EN 10204 3.1 | Full traceability documentation provided; third-party inspection available (SGS, BV, TÜV) |
| Packaging | Bundled in 2–5 MT bundles; steel-strapped; seaworthy packing available | Standard bundle weight per mill practice; export packaging with moisture-resistant wrapping on request |
| MOQ | 25 MT per order | Mixed diameter orders accepted; lower MOQ negotiable for sample or trial orders |
Initial shipment had a labelling issue — resolved promptly, quality was fine
We ordered 18 tons of 16 mm and 25 mm BS 4449-compliant deformed bar for a residential staircase and load-bearing wall project in Birmingham. The steel itself tested correctly — yield and tensile values met Grade B500B requirements — but two bundles in the first delivery had mislabelled heat numbers that didn't match the MTR. This caused a half-day hold on site while we waited for clarification. To their credit, the supplier's team responded within two hours, issued a corrected documentation pack, and our inspector accepted the material the same afternoon. Quality of the steel was never in doubt; documentation process just needs tightening.
