Deformed Reinforcement Bar Supplier | 8–40 mm

Reinforcement bar

Request deformed reinforcement bars to the project-approved grade, diameter and length. EMRA Steel reviews the specification, quantity, inspection documents and destination before confirming an offer. The catalogue covers thirteen enquiry diameters from 8 to 40 mm; it is not a stock list.

Rebar Diameter and Nominal Mass Guide

Masses are geometric estimates using area πd²/4 and density 7850 kg/m³, rounded to three decimals. They are not certified shipment weights or universal standard-table values. Diameter, spacing and intended use must follow the approved structural design; no application or load capacity is assigned from diameter alone.

Reinforcing Steel Rebar Technical and Buying Guide

Reinforcing Steel Rebar Technical and Buying Guide

EMRA Steel supports enquiries for reinforcing steel used in concrete construction. Supply specifications should follow the project design and destination-market requirements. Send the bar diameter, grade, standard, length, quantity and delivery destination for review.

Product Form and Manufacturing

Ribbed reinforcing bars are distinct from smooth engineering round bars and wire rod. Confirm whether the order requires straight bars, coils or fabricated reinforcement. Rib geometry, mechanical properties and inspection requirements must comply with the specified reinforcement standard.

Diameters, Lengths and Packaging

Enquiry sizes include 8, 10, 12, 14, 16, 18, 20, 22, 25, 28, 32, 36 and 40 mm. State the required length; 12 m is one enquiry example. Confirm alternative lengths, bundle requirements and dimensional or mass tolerances with the quotation. Listed sizes are not a confirmed stock range.

Rebar Grades and Applicable Standards

EN 10080 sets general requirements for weldable reinforcing steel. A complete order must also name the applicable product specification and grade. Depending on project requirements, enquiries may reference BS 4449 or ASTM A615/A615M. Specify the full strength and ductility designation, welding requirements and the standard edition. National grade labels are not automatically equivalent across standards.

Applications and Design Requirements

Reinforcement is used in concrete foundations, beams, columns, walls and slabs. Diameter and spacing must follow the structural design; a larger diameter is not a substitute for an approved design. Provide any bending, cutting, welding or seismic-performance requirements with the enquiry.

Inspection and Traceability

Agree the required heat identification, chemical analysis, tensile and ductility results, dimensional checks and inspection documents before ordering. Any independent inspection or additional project testing should be included in the purchase specification.

Rebar Frequently Asked Questions

Can I substitute another grade?

Only after the project requirements and the proposed material have been reviewed by the responsible technical team. Grade names alone do not establish equivalence.

Are all sizes available immediately?

No. Confirm the exact diameter, grade, length and quantity with EMRA Steel before placing an order.

Mechanical grade references

B500B and B500C values below are characteristic values under the BS 4449:2005 family, not guaranteed individual minima. B500C has both a lower and an upper tensile/yield ratio. ASTM grade rows show minimum yield references in the SI system; full tensile, elongation, bend, size and edition requirements still apply. DIN 488 and BS 4449 grades are not automatically equivalent. A legacy Grade 75 request needs its exact standard edition and project approval.

Mechanical grade references
Grade / reference	Yield strength (MPa)	Rm/Re	Agt (%)
B500B	500	≥ 1.08	≥ 5.0
B500C	500	1.15–1.35	≥ 7.5
ASTM A615 Grade 60 [420]	420	—	—
ASTM A615 Grade 80 [550]	550	—	—

Chemical reference composition

The B500B row is a published producer reference for BS 4449; the ASTM rows are separate published reference summaries. These are not EMRA heat results, a complete acceptance specification or proof of availability. Heat/cast and product analyses have different acceptance rules. Confirm the grade, edition, analysis basis, residual elements and permitted variations against the purchase specification and actual mill test results; do not apply a B500B producer row to B500C without checking its governing specification.

Reference limits, % by mass
Reference	C max. (%)	P max. (%)	S max. (%)	CE / CEV max. (%)
BS 4449 B500B — producer reference	0.22	0.050	0.050	0.50 (CEV)
ASTM A615 Grade 60 — published reference	Not specified in this reference	0.060	Not specified in this reference	Not specified in this reference
ASTM A706 — published reference	0.30	0.035	0.045	0.55 (CE)

Check the actual heat analysis against the mill test certificate and the agreed purchase specification. If an EN 10204 type 3.1 inspection certificate is required, confirm its availability and test scope with the offer before ordering.

Carbon Equivalent and Welding

BS-type CEV and ASTM A706 CE use different formulas and must not be compared as if they were the same parameter. BS-type CEV = C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15. The cited A706 reference uses CE = C + Mn/6 + Cu/40 + Ni/20 + Cr/10 − Mo/50 − V/10. Use the formula and acceptance rules of the agreed standard and edition. A welding procedure and project approval remain necessary; a low carbon equivalent alone does not authorize site welding.

Rib Geometry, Markings and Traceability

Agree rib height, spacing, inclination and relative rib area fR or the governing bond-performance acceptance method with the specified standard. Crescent, chevron or other rib appearances do not certify a grade. Rolled markings and bundle tags must be interpreted using the producer and standard marking system and linked to heat or batch records. Do not identify grade, nominal size or seismic suitability from a photograph alone.

Inspection, Packing and Delivery

Specify any EN 10204 type 3.1 inspection document, heat identification, chemistry, tensile/ductility and bend/rebend testing before purchase; document availability and scope are confirmed with the offer. Agree bundle mass, strapping, lifting and corrosion protection rather than assuming 2–3 tonne bundles or a fixed container payload. Name the actual place or port under Incoterms 2020: FOB names the shipment port, CFR/CIF the destination port and DAP the destination place. Existing market sections cover Georgia/Tbilisi, UAE/Dubai, Turkey/Istanbul, Kuwait, Oman and Qatar; route feasibility, customs and unloading responsibilities require confirmation.

Rebar Price and Purchase Enquiry

Grade, diameter, straight length, quantity, cutting or bending, inspection scope, packing, freight and shipment date affect the offer. Send the full standard and edition, project-approved grade, required tonnes and named city or port. Request confirmation of supply, document scope and commercial terms; the website does not promise stock, fixed prices or universal certification.
