|---|---|---|
| Product Name | Mild Steel Bars for Building Construction | Low carbon steel bars widely used in structural and reinforcement applications |
| Material Grade | S235JR / A36 / Q235B / SS400 | International equivalents: EN 10025 S235JR, ASTM A36, GB/T 700 Q235B, JIS G3101 SS400 |
| Standard Compliance | ASTM A36, EN 10025-2, GB/T 700, JIS G3101 | Meets major international structural steel standards for building and construction use |
| Carbon Content (C) | ≤ 0.25% | Low carbon content ensures good weldability and ductility |
| Manganese (Mn) | 0.60% – 1.65% | Enhances strength and hardness without reducing ductility |
| Phosphorus (P) | ≤ 0.040% | Controlled to prevent brittleness in finished bars |
| Sulfur (S) | ≤ 0.050% | Kept low to maintain toughness and weldability |
| Silicon (Si) | ≤ 0.40% | Acts as a deoxidizer during steel manufacturing |
| Tensile Strength | 400 – 550 MPa | Per ASTM A36 / EN 10025-2; ensures structural load-bearing capacity |
| Yield Strength | ≥ 235 MPa (S235JR) / ≥ 250 MPa (A36) | Minimum yield point suitable for general structural construction |
| Elongation | ≥ 20% (in 200 mm gauge length) | High elongation provides ductility and resistance to sudden fracture |
| Size Range | Diameter: 6 mm – 100 mm; Length: 6 m – 12 m | Available as round bars, square bars, and flat bars; custom lengths on request |
| Surface Finish | Hot Rolled, Black Surface / Pickled / Galvanized | Standard hot-rolled mill finish; surface treatment options available per order |
| Application | Structural frames, columns, beams, foundations, reinforcement | Suitable for residential, commercial, and industrial building construction projects |
| Certification | ISO 9001, Mill Test Certificate (EN 10204 3.1/3.2), CE Marking | Full material traceability with third-party inspection available upon request |
| Packaging | Bundled in 2–3 MT bundles, steel-strapped; seaworthy export packing available | Bundles labeled with grade, heat number, and dimensions for easy identification |
| MOQ | 5 Metric Tons per size/grade | Mixed container orders accepted; bulk pricing available for orders ≥ 25 MT |
Initial documentation delay resolved — product quality was fine
We ordered 25 tonnes of 16 mm deformed bars to BS 4449 Grade B500B for a school extension project in Manchester. The bars themselves met spec — yield strength confirmed at 510 MPa, CE value at 0.41%. However, the mill test certificates were not included in the first shipment, which held up our site engineer's sign-off by nearly three days. After raising the issue, the supplier sent the full documentation package within four hours and apologized. Problem resolved, no impact on final program. Product quality is not in question; just ensure documentation is dispatched with the goods.
