| Material Grade | A36 / A992 / S235JR / S355JR / Q235B / Q345B / SS400 | ASTM A36 ≈ S235JR ≈ Q235B; ASTM A992 ≈ S355JR ≈ Q345B; JIS SS400 equivalent |
| Standard Compliance | ASTM A6 / EN 10034 / JIS G3192 / GB/T 11263 | Dimensional tolerances per ASTM A6 (US), EN 10034 (Europe), JIS G3192 (Japan), GB/T 11263 (China) |
| Chemical Composition (C) | ≤ 0.26% (A36) / ≤ 0.23% (Q345B) | Carbon content controls weldability and hardness |
| Chemical Composition (Mn, Si, P, S) | Mn ≤ 1.60%, Si ≤ 0.40%, P ≤ 0.035%, S ≤ 0.035% | Per ASTM A36 / EN 10025-2 S355JR typical values |
| Tensile Strength | 400–550 MPa (S235JR) / 470–630 MPa (S355JR) / 400–550 MPa (A36) | Per EN 10025-2 and ASTM A36; higher grades available upon request |
| Yield Strength | ≥ 235 MPa (S235JR / A36) / ≥ 345 MPa (S355JR / Q345B) | Minimum yield strength at thickness ≤ 16 mm per respective standards |
| Elongation | ≥ 20% (S235JR) / ≥ 22% (A36) / ≥ 20% (S355JR) | Longitudinal elongation at fracture per EN 10025-2 / ASTM A36 |
| Section Size Range (H × B) | 100×100 mm – 900×300 mm (HW/HM/HN series) | Web height (H) × flange width (B); covers light, medium and heavy series per GB/T 11263 / EN 10034 |
| Flange Thickness | 6 mm – 40 mm | Varies by section designation; heavier sections have thicker flanges for higher load capacity |
| Length | 6 m – 18 m (standard) / custom lengths available | Standard mill lengths 6 m, 9 m, 12 m; cut-to-length service available |
| Unit Weight Range | 8.0 kg/m – 270 kg/m | Indicative weight per meter; e.g., H100×100 ≈ 17.2 kg/m, H400×400 ≈ 172 kg/m |
| Surface Finish | Hot-rolled mill scale (black) / shot-blasted / primer-coated / galvanized | Standard delivery in mill scale; anti-corrosion treatment available per customer specification |
| Application | Building frames, bridges, industrial plants, columns, beams, crane rails, offshore structures | Widely used in civil, structural and heavy engineering construction worldwide |
| Certification | ISO 9001 / CE Marking / Mill Test Certificate (EN 10204 3.1 / 3.2) | Third-party inspection by SGS, BV, TÜV available; full traceability documentation provided |
| Packaging | Bundle with steel strip (3–5 MT per bundle) / bare / containerized | Seaworthy export packing; moisture-proof wrapping available for ocean freight |
| MOQ | 25 MT per order (mixed sizes acceptable) | FOB / CIF pricing available; price varies by grade, size, quantity and market conditions |
Initial sizing mix-up on 900×300 order — resolved quickly, quality was fine
We placed an order for 85 MT of 900×300 H beams in ASTM A992 for a heavy machinery base application. On arrival, approximately 12 pieces were labelled with incorrect heat numbers that did not match the 3.1 certificates, creating a traceability concern for our client's QA audit. We raised this immediately and the supplier re-issued corrected documentation with matching heat traceability within 48 hours. The physical steel itself — 16 mm web, 28 mm flange, 243 kg/m unit weight — was fully on-spec and yield strength test results confirmed Grade 50 compliance. Issue resolved, and we have since placed a follow-up order.
