Technical Specifications of BS Standard Reinforcing Steel Bars

Property	Parameter	Description
Product Name	BS Standard Reinforcing Steel Bars	Deformed and plain steel bars for concrete reinforcement per British Standard
Material Grade	B500B / B500C (BS 4449:2005+A3:2016)	Equivalent to EN 10080 Grade B500B/B500C; formerly Grade 460B under BS 4449:1997
Standard Compliance	BS 4449:2005+A3:2016 / BS 4449:1997	Complies with EN 10080; also references BS 8666 for scheduling and BS 6744 for stainless rebar
Chemical Composition – Carbon (C)	≤ 0.22% (B500B); ≤ 0.50% CEV	Carbon equivalent (CEV) controls weldability; lower C improves ductility
Chemical Composition – Manganese (Mn)	≤ 1.60%	Enhances strength and hardenability of the bar
Chemical Composition – Phosphorus (P)	≤ 0.050%	Controlled to prevent cold brittleness
Chemical Composition – Sulfur (S)	≤ 0.050%	Limited to avoid hot shortness and reduce inclusions
Tensile Strength (Rm)	≥ 540 MPa (B500B); ≥ 540 MPa (B500C)	Rm/Re ratio ≥ 1.08 (B500B); ≥ 1.15 and ≤ 1.35 (B500C) per BS 4449:2005+A3:2016
Yield Strength (Re)	500 MPa nominal (characteristic value ≥ 500 MPa)	Upper yield strength or 0.2% proof stress; tolerance range 500–650 MPa typical
Elongation (Agt)	≥ 5.0% (B500B); ≥ 7.5% (B500C)	Total elongation at maximum force; higher Agt indicates superior ductility class
Ductility Class	Class B (B500B); Class C (B500C)	Class C preferred for seismic and high-ductility structural applications
Diameter Range	6 mm – 50 mm	Common stock sizes: 6, 8, 10, 12, 16, 20, 25, 32, 40, 50 mm; custom sizes available
Length	6 m / 12 m standard; cut-to-length available	Coil form available for diameters 6–16 mm; straight bars for larger diameters
Surface Finish	Hot-rolled deformed (ribbed) / plain round	Transverse ribs and longitudinal ribs improve bond strength with concrete; mill scale surface
Application	Reinforced concrete structures, bridges, tunnels, foundations, seismic zones	Widely used in UK construction, infrastructure, and civil engineering projects
Certification	CARES UK, CE Marking (DoP), ISO 9001	CARES certification is the primary UK third-party approval scheme for rebar compliance
Packaging	Bundled in 2–5 MT bundles; wire-tied or steel-strapped	Bundles labeled with heat number, grade, diameter, and standard; seaworthy packing on request
MOQ	25 MT per order (negotiable)	Mixed diameter orders accepted; mill direct or stockholder supply available

BS Standard Reinforcing Steel Bars - Mill Direct Supplier

BS standard reinforcing steel bars serve as the structural backbone of modern construction projects across the United Kingdom, Europe, and global markets that recognise British Standards compliance. Manufactured in strict accordance with BS 4449:2005+A3:2016 — the definitive specification governing carbon steel bars for the reinforcement of concrete — these rebars deliver the dimensional precision, mechanical reliability, and metallurgical consistency that demanding civil engineering applications require. Whether you are sourcing material for high-rise residential towers, bridge decks, tunnels, or industrial foundations, selecting a mill-direct supplier eliminates unnecessary intermediary costs while ensuring full traceability from melt to dispatch. Our facility produces deformed and plain round bars in grades B500A, B500B, and B500C, covering yield strengths from 500 MPa with controlled ductility classes to suit seismic and non-seismic design environments. With certified third-party testing, CE marking, and CARES accreditation available, every coil and straight bar we ship meets the rigorous quality benchmarks your structural engineers specify.

What Are BS Standard Reinforcing Steel Bars?

BS standard reinforcing steel bars are hot-rolled deformed or plain carbon steel bars produced to British Standard BS 4449, designed to bond with concrete and resist tensile, compressive, and shear forces within reinforced concrete structures. Available in nominal diameters ranging from 6 mm to 50 mm and supplied as straight lengths up to 12 m or in coil form, they are classified by ductility grade — B500A, B500B, and B500C — each defining specific elongation and strain-hardening ratios critical to structural safety and seismic performance.

Initial shipment delay resolved – product quality confirmed to spec

Our first order of 80 tonnes of B500B bars in 20 mm and 28 mm diameters experienced a five-day dispatch delay beyond the originally quoted lead time, which created a short scheduling issue on our bridge project site. After raising the concern, the logistics team provided daily updates and expedited the customs documentation. Bars arrived and were tested by our independent lab – yield strength at 518 MPa, Agt at 5.8%, both compliant with BS 4449:2005+A3:2016. EN 10204 3.1 certificates were accurate and complete. The supplier acknowledged the delay and offered a partial freight credit. Willing to order again given the quality.

Competitive mill-direct pricing for a 150-tonne BS 4449 order

Sourced 150 tonnes of B500B deformed bars in 12 mm, 16 mm, and 25 mm for a commercial building project in Dubai where the client specification mandated BS 4449 compliance. Mill-direct pricing saved approximately 8% compared to regional distributor quotes for equivalent certified material. CE marking and CARES documentation were accepted by the project consultant without revision. Delivery to Jebel Ali port took 22 days, which was within the agreed window. Communication during transit could be slightly more proactive, but the product quality and certification package were exactly as described.

Good value on B500A coil – minor labelling query resolved quickly

Purchased 60 tonnes of B500A coil in 8 mm and 10 mm for prefabricated mesh production. Mill pricing was noticeably lower than local distributors for equivalent BS 4449-certified material. Mechanical properties met spec – Agt results came in at 3.1% to 3.8%, above the 2.5% minimum. One bundle had a labelling discrepancy between the tag and the certificate heat number, which initially caused a hold in our intake process. The supplier resolved it within one business day by issuing a corrected certificate. Overall good experience and fair value for certified BS material at this volume.
