As a trusted manufacturer of steel reinforcement products, Hemaokang Steel (Shandong) Co., Ltd. proudly presents our 6m Length Reinforcing Steel Bar BS4449 B500B 8mm to 25mm Ribbed Deformed Bar, specifically engineered for concrete slab applications. With an annual export value exceeding US$50 million and a dedicated team of 51-100 skilled professionals, we ensure every bar meets the highest standards of quality and consistency. Our deformed bars feature a ribbed surface that provides superior bond with concrete, making them ideal for structural reinforcement in slabs, beams, and foundations.
Our product is manufactured under strict quality control and complies with the BS4449 B500B standard, ensuring reliable performance in demanding construction environments. Available in diameters from 8mm to 25mm and a standard length of 6 meters, these bars offer versatility for projects of all scales. The B500B grade guarantees a minimum yield strength of 500 MPa, providing the necessary tensile strength for safe and durable concrete structures.
Product Features & Advantages
- Full Compliance: Fully meets BS4449 B500B standards, ensuring compatibility with international building codes.
- Excellent Bond Strength: Ribbed surface design increases mechanical interlock with concrete, minimizing slippage and enhancing structural integrity.
- Wide Size Range: 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm – available to suit various slab thicknesses and load requirements.
- Optimal Length: 6-meter standard length reduces waste and simplifies handling on construction sites. Custom lengths available upon request.
- High Ductility: B500B grade offers excellent elongation and bendability, allowing easy shaping for complex reinforcement layouts.
- Corrosion Resistance: Standard black finish with optional epoxy coating or galvanization for enhanced durability in aggressive environments (customizable).
- Consistent Quality: ISO9001 certified production process ensures dimensional accuracy, uniform rib pattern, and reliable mechanical properties.

Frequently Asked Questions (FAQ)
1. What does BS4449 B500B mean?
BS4449 is the British standard for steel bars for concrete reinforcement. B500B indicates a yield strength of 500 MPa minimum, and 'B' class ductility with specific elongation and bend requirements. Our bars fully comply with this standard.
2. Can I order custom lengths other than 6m?
Yes, we offer customized lengths upon request. Please discuss your requirements with our sales team for feasibility and lead time.
3. What is the packing method for export?
Bars are bundled with steel straps, securely packed for sea freight. Options include loose bundles, palletized, or in containers. Edge protection and waterproof wrapping are available upon request.
4. Do you provide a mill test certificate?
Absolutely. Each batch comes with a Mill Test Certificate (MTC) showing chemical composition, mechanical properties, and compliance with BS4449 B500B. Third-party inspection is also welcome.
5. What is the minimum order quantity (MOQ)?
Our standard MOQ is 25 metric tons per size, but we can accommodate smaller trial orders for new customers. Contact us for details.
6. Can these bars be bent or cut on site?
Yes, the B500B grade offers good ductility, allowing bending and cutting with proper equipment. For large-scale projects, we can also provide pre-cut and pre-bent bars as a value-added service.
7. What is the typical delivery time?
For standard sizes and quantities, delivery is usually 15-25 days after order confirmation, depending on production schedule and shipping destination.
8. Are your bars suitable for seismic zones?
BS4449 B500B bars have good ductility and energy absorption capacity, making them suitable for seismic applications. However, always consult local structural engineering codes for specific requirements.
