When you need BS4449 rebar for reinforced concrete construction, UK-related project specifications, contractors, distributors or export supply, you can send grade, diameter, length, quantity, bundle weight, MTC requirement and destination details. Bao Steel (Qingdao) Co., Ltd. supports B500A, B500B and B500C weldable reinforcing steel, with grade review, document support, bundle packing and export shipment coordination.
BS4449 rebar is mainly selected by ductility class. B500A, B500B and B500C share the same 500 MPa characteristic yield strength, but their tensile/yield strength ratio and elongation requirements are different. You should confirm grade, diameter, length, quantity, MTC requirement and project acceptance details before quotation.
You can request B500A when the project specification accepts lower ductility class reinforcement for suitable concrete reinforcement use.
You can choose B500B when the project requires 500 MPa reinforcement with medium ductility and common UK-related specification acceptance.
You can select B500C when the project requires higher ductility class reinforcement and stricter acceptance details.
You can discuss straight bar, coil or decoiled reinforcement supply when the project or distributor order specifies delivery form.
The three BS4449 grades are not separated by yield strength only. They are separated mainly by tensile/yield ratio and total elongation at maximum force. This helps buyers choose the correct ductility class according to project drawings and structural requirements.
| BS4449 Grade | Characteristic Yield Strength | Tensile / Yield Ratio | Agt Requirement | Buyer Selection Logic |
|---|---|---|---|---|
| B500A | 500 MPa | Rm/Re ≥ 1.05 | Agt ≥ 2.5% | Selected only when the project accepts lower ductility class reinforcement. |
| B500B | 500 MPa | Rm/Re ≥ 1.08 | Agt ≥ 5.0% | Common choice for many UK-related reinforcement requirements requiring medium ductility. |
| B500C | 500 MPa | Rm/Re ≥ 1.15 and < 1.35 | Agt ≥ 7.5% | Selected when the project needs higher ductility class and stricter deformation performance. |
This comparison is not for automatic material substitution. It is designed to help buyers explain their project standard clearly before quotation. Final acceptance must follow local design codes, project drawings, engineering approval and MTC documents.
| Standard / Grade | Typical Strength Level | Main Market / Use | Ductility / Acceptance Focus | Best Quotation Approach |
|---|---|---|---|---|
| BS4449 B500B / B500C | 500 MPa characteristic yield strength | UK-related, Commonwealth-related, Middle East and project specifications using BS reinforcement. | Key difference is ductility class. B500B and B500C are selected by Rm/Re and Agt requirements. | Send grade, diameter, length, quantity, MTC requirement and whether B500B or B500C is specified. |
| ASTM A615 Grade 60 | 60 ksi / about 420 MPa minimum yield strength | US-related, Latin America, Middle East and projects referencing ASTM reinforcement. | Grade is based on ksi yield strength. A615 is carbon steel rebar and should not be treated as direct BS4449 equivalent without approval. | Send ASTM grade, bar size, length, bundle weight, destination and MTC requirement. |
| HRB400 | 400 MPa yield strength level | China / GB-related reinforced concrete projects and buyers using HRB grade naming. | Common hot rolled ribbed bar grade. E version should be reviewed separately if seismic control is required. | Send HRB grade, diameter, length, bundle weight, GB / project standard and destination. |
| HRB500 | 500 MPa yield strength level | Higher strength GB-related reinforcement projects where HRB500 is approved by design. | Closer yield strength level to BS4449 B500 grades, but standard system, ductility and testing requirements are still different. | Send project standard, whether E grade is required, diameter, length, MTC and inspection requirements. |
We support BS4449 rebar sourcing for importers, distributors, contractors, construction companies and infrastructure project buyers who need grade confirmation, MTC documents, bundle packing and export shipment support.
B500A is used when the project accepts lower ductility class reinforcement and clearly specifies this grade.
B500B is commonly requested for BS4449 reinforcement projects requiring 500 MPa yield strength and medium ductility class.
B500C is selected when the buyer needs higher ductility class reinforcement and stricter deformation performance acceptance.
Cut length, coil or decoiled product requirements can be reviewed according to project supply and distributor handling needs.
BS4449 rebar quotation should not be based only on grade name. Diameter, length, quantity, bundle weight, ductility class, test requirement, packing method, destination and project document all affect pricing and delivery feasibility.
BS4449 rebar buyers often compare price first, but receiving disputes usually come from grade mismatch, unclear heat number, missing test details, wrong bundle marks or poor loading records. These details should be checked before shipment.
You can confirm whether B500A, B500B or B500C matches the required ductility class in the project specification.
You can request tensile/yield strength ratio and total elongation at maximum force details when project acceptance requires them.
You can confirm bend and re-bend test requirements when the project document requires additional ductility or site acceptance checks.
You can align heat number, MTC, bundle labels, grade marks, shipping marks and loading photos before shipment.
You can review diameter, rib condition, grade marks, bundle labels, MTC consistency, packing condition and loading photos before shipment. These details matter for importers, distributors, contractors and project buyers.
You can review rebar bundles, diameter range, warehouse handling and export-ready stock condition.
You can confirm bar diameter, rib condition, surface condition, straightness and order consistency.
You can align bundle tags, heat number, MTC, grade, quantity and document details before loading.
You can request steel straps, tags, bundle marks, shipping marks and bundle weight confirmation.
You can review container stuffing, loading protection, shipping marks and loading photos before shipment.
BS4449 rebar is mainly used for reinforced concrete projects where British standard reinforcement, grade class, ductility, bar size, bundle packing and test documents must match buyer project requirements.

B500A, B500B and B500C all have 500 MPa characteristic yield strength, but their tensile/yield strength ratio and Agt requirements are different. B500C has higher ductility requirements than B500B, while B500A is lower ductility class.
No. BS4449 and ASTM A615 belong to different standard systems. Even if strength levels look close, ductility rules, chemical requirements, bar marking and project acceptance may be different.
Not automatically. HRB500 and BS4449 B500 grades may share a similar yield strength level, but standard rules, ductility class, test method and project acceptance are different. Engineering approval is required for substitution.
Yes. MTC, heat number, chemical composition, mechanical properties, packing photos, shipping marks and loading photos can be discussed according to order requirements.
