What Is ASTM A615 Rebar? Specifications, Features and Supply from China

As global construction and infrastructure projects continue to grow, reliable reinforcing steel remains essential for concrete structures. ASTM A615 rebar is widely used in building, bridge, road, tunnel and other reinforced concrete projects.

What Is ASTM A615 Rebar?

ASTM A615/A615M is a standard specification for deformed and plain carbon-steel bars used for concrete reinforcement. It covers key requirements for dimensions, chemical composition and mechanical properties, including tensile, yield, elongation and bending performance.

Under the current ASTM A615/A615M-26 specification, available strength grades include Grade 40, Grade 60, Grade 80 and Grade 100. For international projects, buyers should confirm the required ASTM edition and grade before ordering.

Key Features of Deformed Rebar

ASTM A615 deformed rebar features longitudinal and transverse ribs that improve mechanical bonding between steel and concrete. The ribbed surface helps reduce slippage and provides reliable reinforcement within concrete structures.

Hot-rolled rebar also offers stable mechanical performance, including good tensile strength, bending capability and ductility. Consistent dimensions and rib patterns are important for maintaining reliable structural performance.

Specifications and Supply Options

ANLI supplies hot-rolled deformed rebar in diameters from 6–50 mm, including 6, 8, 10, 12, 16, 18, 20, 22, 25, 28, 32, 36, 40, 45 and 50 mm. Customized lengths and specifications are available according to project requirements.

Products can be supplied according to different market standards, including ASTM, JIS and GB, with grades such as ASTM A615 Grade 40/60/80/100 and Chinese HRB335, HRB400 and HRB500. Grade 75 may also be supplied where required under an applicable specification or edition.

Applications

Deformed rebar is widely used for reinforced concrete structures, including:

High-rise buildings · Foundations · Bridges · Roads · Tunnels · Industrial Buildings · Infrastructure Projects

It works together with concrete to provide reinforcement and help structural components withstand tensile forces.
