ASTM A615 Steel Rebar is a premium hot-rolled deformed rebar for concrete reinforcement, the mainstream specification in North American construction with Grade 40, 60 and 75 as core grades, corresponding to yield strengths of 40, 60 and 75 ksi. It features excellent bonding performance with concrete, reliable weldability and cold workability for on-site processing, and strict dimensional accuracy. With stable tensile strength, good ductility and fatigue resistance, it’s cost-effective and compliant with North American construction codes, serving as the core reinforcement material for various concrete structure projects in the US and Canada.
