Selecting the right reinforcing bar (rebar) grade is one of the most critical decisions in any concrete project. The grade defines the yield strength, ductility and weldability of the steel, and the wrong choice can compromise both safety and budget. BeLink Global supplies every major international grade, and this guide explains how to choose.
What a Rebar Grade Actually Means
A grade specifies the minimum yield strength of the bar. For example, ASTM A615 Grade 60 guarantees a minimum yield of 420 MPa, while BS 4449 B500B guarantees 500 MPa. Higher grades carry more load with less steel, but can be less ductile.
The Main International Standards
- ASTM A615: Grades 40, 60, 75, 80
- ASTM A706: low-alloy, weldable, ideal for seismic zones
- BS 4449 / EN 10080: B500A, B500B, B500C by ductility
- GOST 5781: A400, A500C, A600
How to Decide
Match the grade to your structural design, seismic requirements and local building code. For high-rise or earthquake-prone projects, choose weldable A706 or high-ductility B500C. For standard construction, A615 Grade 60 offers the best balance of cost and strength. Compare full specifications on our Deformed Rebar page and estimate tonnage with the weight calculator.
