reinforcement concrete bars mill manufacturer Grasping strong production capability, advanced research strength and excellent service, Shanghai reinforcement concrete bars mill supplier create the value and bring values to all of customers.
Deformed steel bars have ribs, lugs and indentation on the surface of the bar, which reduces the major problem that is faced by mild steel bar due to slippage and good bonding is achieved between concrete and rebar. The tensile properties is higher compared to other rebars. These bars are produced in sections from 6 mm to 50 mm dia.
