◉Product Description
We supply high-strength Grade 60 and Grade 80 steel reinforcing bars (rebar) manufactured according to ASTM A615 and ASTM A706 standards. These deformed carbon-steel bars are designed for concrete reinforcement in commercial, industrial, and infrastructure projects.
Grade 60 (420 MPa) rebar offers a minimum yield strength of 60,000 psi, making it the industry standard for medium to heavy-duty concrete reinforcement applications including foundations, bridge decks, parking structures, and high-rise buildings .
Grade 80 (550 MPa) rebar delivers a minimum yield strength of 80,000 psi, enabling reduced steel congestion in highly reinforced members while maintaining structural integrity. Recent seismic performance studies confirm that Grade 80 rebar can match the displacement capacity of Grade 60, making it a suitable alternative for earthquake-resistant bridge columns and seismic design applications .
Both grades are available in diameters from #3 (3/8″) to #11 (1-3/8″), with standard lengths of 20 ft, 40 ft, or custom cut-to-length options . The deformed surface pattern with raised ribs ensures superior bond strength with concrete, preventing slippage under load.
