A615

A615 is an ASTM International standard specification for reinforcing steel bars used in concrete. The designation typically refers to hot-rolled bars that are intended to serve as reinforcement in structural and other concrete applications. The specification is published as A615/A615M and exists in inch-pound (A615) and metric (A615M) versions, reflecting its wide use in the United States and abroad.

The standard covers both deformed and plain reinforcing bars and sets requirements for material quality, surface

A615 specifies the diameters typically used in reinforcement, general tolerances for length and straightness, and requirements
