Source ASTM-grade reinforcing bars for concrete construction projects, distributors and fabrication programs. Compare A615 carbon-steel rebar and A706 low-alloy rebar by grade, bar number, test documentation and approved project requirements.
Tell us your ASTM edition, grade, bar size schedule, cut lengths, project tonnage and destination port.
Start with the applicable standard and grade, then confirm nominal bar number, test requirements, delivery format and project-approved detailing.
ASTM steel rebar refers to reinforcing steel ordered to a defined ASTM specification. The two principal specifications covered here are ASTM A615 for carbon-steel reinforcing bars and ASTM A706 for low-alloy bars with additional controls related to mechanical performance and weldability.
Purchase orders should name the exact standard edition, grade, bar size, cut or coiled form, expected quantity and applicable mill test reports. For seismic detailing, welding or mechanical splices, follow the structural engineer's approved design and governing code.
Select one of the three grade-specific pages below for detailed material information. This hub focuses on specification selection, nominal weight planning and bulk project enquiries.
Share your bar numbers, lengths, quantities and required certificates for a project-specific quotation.
The equivalent nominal diameter used in ASTM size tables is not the outside measurement across raised ribs.
Three dedicated enquiry pages connect your bar schedule to the required mechanical properties, inspection provisions and current standard scope.
Common structural reinforcement designation with a specified minimum yield of 60 ksi [420 MPa]. Used for reinforced concrete work when permitted by the project specification.
Legacy Grade 75 [520] was removed from A615's main concrete-reinforcement grades in 2018. The annex treatment concerns other applications; original drawings, edition and intended use need review.
Grade 60 [420] low-alloy reinforcement with controlled chemical composition and tensile-property requirements relevant to applications involving welding or tighter mechanical controls.
Current ASTM A615/A615M-26 scope lists Grades 40, 60, 80 and 100 for its main concrete-reinforcement requirements. Grade 75 is addressed separately for other applications under Annex A2. Do not substitute grades or represent Annex A2 material as approved structural reinforcement without the design authority's acceptance.
Both cover reinforcing bar, but the standards address chemistry and tensile-property control differently. The correct choice depends on the project specification and design intent.
Include the exact contract editions and required mill certification. A706 compatibility with A615 should be verified by grade, size, marking, MTC and project acceptance.
A grade number is a minimum specified yield level—not a complete description of chemistry, weldability, ductility, form or project acceptance.
| Product Page | Minimum Yield Designation | Key Procurement Difference | Specification Status |
|---|---|---|---|
| A615 Grade 60 | 60 ksi [420 MPa] | Carbon-steel reinforcement; welding review is project-specific. | Included in the current A615 main scope. |
| A615 Grade 75 | 75 ksi [520 MPa] — historical level | Legacy drawings or defined other-application enquiries; edition and design approval essential. | Removed from main concrete-rebar scope in 2018; Annex A2 covers other applications. |
| A706 Grade 60 | 60 ksi [420 MPa] | Low-alloy chemistry and controlled tensile provisions intended to support weldability or controlled-performance use. | Included in current A706 main scope. |
The question matters when older concrete drawings or bills of material continue to use the 75 ksi designation.
In ASTM A615/A615M-18ε1, Grade 75 [520] was moved out of the principal concrete-reinforcement grade listing. Annex A2 introduced provisions for Grade 75 in certain non-concrete-reinforcement applications. In 2026, the A615 main scope continues to recognize Grades 40, 60, 80 and 100.
Obtain the original ASTM edition and drawings. Any proposed Grade 80 substitute or change in use must be reviewed and accepted by the engineer of record or relevant design authority.
A clear purchase order is the fastest path to a technically accurate quotation and to receiving material that meets the agreed project requirements.
| Purchase Item | Recommended RFQ Details | Why It Matters |
|---|---|---|
| ASTM Standard & Edition | A615/A615M-26 or A706/A706M-26a, or precisely named contract edition | Governs manufacturing, testing and acceptance criteria. |
| Rebar Grade | Grade 60 [420], A706 Grade 60 [420], or separately reviewed historic designation | Yield level alone does not define every requirement. |
| Nominal Bar Number | US #3 to #18 schedule; indicate SI A615M/A706M if ordering metrically | Controls nominal geometry and quantity calculations. |
| Delivery Form | Straight bar, approved cut length or coil where applicable | Impacts processing, packing and shipment planning. |
| Length & Quantity | Length per bar, piece count and/or metric tonnage by size | Allows mixed-size project quotation. |
| Tests & MTC | Chemistry, tension, bending, geometry, heat and lot traceability | Enables batch-specific verification and receipt checks. |
| Project Controls | Weld procedure, splicing, seismic detailing, applicable building code | May create additional approval and test obligations. |
| Logistics | Destination port, packing requirements, inspection and Incoterm | Defines shipping quotation and documentation. |
Use published ASTM bar number designations for takeoffs—not measured ribbed outside diameter. Quotation availability must be confirmed for each grade and size.

Provide the # number, length, quantity and requested grade for each line item.
Match the material form to the size, grade, fabrication method and transport requirements in your purchase order.
Standardized straight lengths or agreed cut lengths for structural reinforcement, distributors and bar fabrication orders. Length and diameter combinations are verified per quotation.
Coils may be requested for suitable sizes and processing routes. Coil feasibility and downstream straightening, bend performance and grade certification need individual confirmation.
Bar markings and transverse ribs support material identification and concrete bond. Check mill identification, bar-size designation, steel type and grade marking against the applicable ASTM edition and MTC. Theoretical mass is based on nominal dimensions rather than rib-height measurements.
Reinforcement requirements are established by project design documents. Product selection and detailing must align with the governing structural code.
Application photos are representative only; a photograph does not establish structural grade certification or compliance.
Material schedules for foundations, footings and pile reinforcement.
Approved longitudinal and transverse reinforcement layouts.
Grade and inspection requirements set by project specifications.
Project-specific lengths, bending and bar schedules for fabrication.
Where the project calls for welding or specified ductility/tensile control, evaluate A706 and any supplementary project requirements with the engineer. Neither designation independently replaces code-compliant detailing or qualified procedures.
Our company-wide manufacturing, inventory and quality systems support grade-by-grade project procurement. Confirm individual size availability and delivery dates during quotation.
Company-wide steel output of 8 million metric tons per year, supporting organized procurement programs across multiple steel categories.
1 million metric tons of regular combined steel inventory across the company. Individual ASTM rebar grades and sizes require live confirmation.
Coordinate mill certificates and applicable grade, chemical, tensile, bend, deformation and heat-identification requirements for the purchase.
Coordinate bundle identification, order packing lists, shipment terms and the documentation requested in the purchasing contract.
Calculate an estimated metric tonnage using nominal mass per metre for your chosen ASTM rebar number, length and quantity.
Planning values only; mill/receiving weights and actual shipment quantity are governed by the contracted measurement method.
For one line item, multiply the bar size's nominal mass (kg/m) by each bar's length (m) and the number of pieces. Divide total kilograms by 1,000 to obtain metric tons.
1.552 kg/m × 12 m × 100 = 1,862.4 kg ≈ 1.862 MT. This estimate excludes scrap allowances, bend allowances and shipment packing.
A clear grade-and-size schedule helps align material procurement, production routing, test records and shipping instructions.
Production routes, lot scheduling and final lead time are confirmed on individual quotations rather than assumed for every rebar grade.
Separate enquiry lines by standard, steel grade, nominal rebar number and preferred cutting length to speed up sourcing and packing decisions.
Company-wide stock figures are not grade-specific. Ask sales to confirm current size/grade combinations, quantities and earliest feasible dispatch before committing to a project schedule.
Group requirements into one schedule of # bar numbers, cut lengths, quantities, agreed test documentation and required packaging by bundle or heat.
Provide destination port and Incoterm. Shipping dates, container planning, bundling method and documentary needs follow final offer acceptance.
The acceptance package should match the exact ASTM edition and the project's quality plan, including any special inspection requirements.
The exact inspection plan depends on grade, diameter, ASTM revision, manufacturing lot and contractual acceptance rules.
Reinforcing steel for export is normally bundled to suit diameter, piece length, handling weight and container or breakbulk transport plans.
Packing configuration and any supplementary protection are confirmed during quotation and shipment planning.
