ASTM A615 Reinforcement Bar Grade 75

Product Overview

ASTM A615 Grade 75 rebar is a high-strength carbon steel reinforcing bar designed for demanding structural applications. With a minimum yield strength of 75,000 psi (520 MPa), this grade offers excellent load-bearing capacity and crack resistance, making it ideal for large-scale and heavy-duty construction projects.

Its ribbed surface pattern ensures superior bonding with concrete, enhancing the composite performance of reinforced structures. This bar meets ASTM A615 / A615M standard specifications for deformed and plain carbon-steel bars used in concrete reinforcement.

Key Features and Advantages

• High yield strength (≥ 75,000 psi) for superior load-bearing structures.
• Excellent tensile performance and ductility for heavy construction environments.
• Available in multiple diameters (8mm–40mm) with standard 12m lengths.
• Strict mill certification available.
• Conforms to ASTM A615 standard, suitable for both primary and secondary reinforcement.
