| Property | Parameter | Description |
|---|---|---|
| Product Name | H Beam Steel | Hot-rolled wide flange H-shaped structural steel beam |
| Material Grade | A36 / SS400 / S235JR / Q235B / S355JR / A992 | International equivalent grades: ASTM A36 ≈ SS400 ≈ S235JR ≈ Q235B; ASTM A992 ≈ S355JR ≈ Q345B |
| Standard Compliance | ASTM A6/A6M, EN 10034, JIS G3192, GB/T 11263 | Dimensional and mass tolerances per respective national and international standards |
| Chemical Composition (C) | ≤ 0.26% (A36) / ≤ 0.23% (S355JR) | Carbon content controlling weldability and hardness |
| Chemical Composition (Mn, Si, P, S) | Mn ≤ 1.60%, Si ≤ 0.50%, P ≤ 0.035%, S ≤ 0.035% | Manganese enhances strength; P and S strictly limited to ensure toughness |
| Tensile Strength | 400–550 MPa (S235JR); 470–630 MPa (S355JR); 400–550 MPa (A36) | Per EN 10025-2 and ASTM A6; higher grades available upon request |
| Yield Strength | ≥ 235 MPa (S235JR / A36); ≥ 345 MPa (S355JR / Q345B) | Minimum yield strength for structural design calculations per EN/ASTM/GB standards |
| Elongation | ≥ 20% (S235JR); ≥ 22% (A36); ≥ 20% (S355JR) | Measured on gauge length L₀ = 5.65√S₀; ensures ductility for seismic and dynamic loads |
| H Beam Size Range (Height × Flange Width) | 100×100 mm to 900×300 mm (HW/HM/HN series) | HW (wide flange): H=B; HM (medium): H≈1.33B; HN (narrow): H≈2B; custom sizes available |
| Web Thickness / Flange Thickness | Web: 5.5–16 mm; Flange: 8–28 mm | Varies by section designation; heavier sections available for high-load applications |
| Standard Length | 6 m, 9 m, 12 m (standard); up to 18 m (custom) | Fixed lengths per mill standard; cut-to-length service available with ±50 mm tolerance |
| Surface Finish | Black (as-rolled), Shot Blasted, Primer Painted, Hot-Dip Galvanized | Standard mill finish is black; galvanized coating ≥ 85 μm per ISO 1461 for corrosion protection |
| Application | Building frames, bridges, industrial plants, columns, crane runways, offshore structures | Widely used in multi-story buildings, heavy machinery bases, and civil engineering projects |
| Certification | ISO 9001:2015, CE Marking (EN 10025), 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 wire/strip; 2–5 MT per bundle | Bundled with dunnage and end caps; sea-worthy export packing with moisture-proof wrapping available |
| MOQ | 25 MT per size/grade | Mixed container orders accepted; spot stock available for standard sizes (100×100 to 400×200 mm) |
Initial surface finish issue on galvanized HW250×250 — resolved satisfactorily
We received 40 tons of hot-dip galvanized HW250×250 for a coastal warehouse project in Gujarat. On arrival, approximately 8% of pieces showed thin zinc coating areas below the 85 µm minimum we specified. We raised a formal NCR with photos within 24 hours. The supplier acknowledged the issue promptly, arranged re-galvanizing of the affected pieces through a local partner at their cost, and delivered replacements within nine days — which kept our site schedule intact. Dimensional specs and base steel chemistry were fine throughout. Supplier's after-sales response was professional; the initial QC lapse was disappointing but the resolution was handled well.
