|---|---|---|
| Product Name | Reinforcing Steel for Bridge Construction | High-strength deformed steel bar used in bridge decks, piers, abutments and prestressed structures |
| Material Grade | HRB400 / HRB500 / Grade 60 / B500B | International equivalents: ASTM A615 Gr.60, EN 10080 B500B, GB/T 1499.2 HRB400/HRB500, JIS G3112 SD390 |
| Standard Compliance | ASTM A615 / A706, EN 10080, GB/T 1499.2, JIS G3112 | Meets bridge-specific structural codes including AASHTO LRFD and BS 5400 |
| Chemical Composition – C | ≤ 0.25% (HRB400) / ≤ 0.28% (HRB500) | Low carbon content ensures weldability and ductility for seismic bridge applications |
| Chemical Composition – Mn | 0.60% – 1.60% | Manganese enhances tensile strength and hardenability |
| Chemical Composition – Si | 0.20% – 0.80% | Silicon improves strength and corrosion resistance |
| Chemical Composition – P & S | P ≤ 0.045%, S ≤ 0.045% | Controlled phosphorus and sulfur minimize brittleness and hot cracking |
| Tensile Strength | ≥ 570 MPa (HRB400) / ≥ 630 MPa (HRB500) | Per GB/T 1499.2; ASTM A615 Gr.60: ≥ 620 MPa; ensures structural integrity under dynamic bridge loads |
| Yield Strength | ≥ 400 MPa (HRB400) / ≥ 500 MPa (HRB500) | Per GB/T 1499.2; ASTM A615 Gr.60: ≥ 420 MPa; critical for load-bearing capacity of bridge elements |
| Elongation | ≥ 16% (HRB400) / ≥ 15% (HRB500) | High elongation ensures ductile failure mode and seismic energy absorption in bridge structures |
| Diameter Range | 6 mm – 50 mm | Common bridge sizes: Ø12, Ø16, Ø20, Ø25, Ø32, Ø40 mm; custom sizes available on request |
| Length | 6 m – 12 m (standard) / up to 18 m (custom) | Fixed or random lengths; cut-to-length service available for bridge project requirements |
| Surface Finish | Hot-rolled deformed (ribbed) surface | Transverse and longitudinal ribs provide superior mechanical bond with concrete; epoxy-coated option available for corrosive environments |
| Application | Bridge decks, piers, abutments, pile caps, retaining walls, prestressed concrete bridges | Suitable for highway, railway, cable-stayed and suspension bridge reinforcement |
| Certification | ISO 9001, CE Marking, Mill Test Certificate (MTC) per EN 10204 3.1 | Third-party inspection by SGS, BV or TÜV available; compliant with AASHTO and Eurocode 2 |
| Packaging | Bundled in 2–5 MT bundles, wire-tied; seaworthy packing available | Labeled with heat number, grade, diameter and standard for full traceability |
| MOQ | 25 MT per order | Mixed grades and sizes accepted; bulk orders above 500 MT qualify for priority scheduling and competitive pricing |
Initial bundle labeling issue — resolved promptly, quality of steel itself was fine
We ordered 220 tons of Grade 80 ASTM A706 bars in #6 and #8 for a bridge abutment project in Abu Dhabi. On arrival at Jebel Ali port, approximately 15% of bundles had heat number tags that did not match the CMTR reference numbers, which flagged an issue during our third-party inspection. We contacted the supplier immediately and they provided corrected documentation and a written explanation within 48 hours — the discrepancy turned out to be a labeling error at the bundling stage, not a material substitution. Mechanical test results were fully compliant: yield ≥550 MPa, CE ≤0.54. Issue resolved, but tighter QC on bundle tagging would prevent this.
