Rebar is a ribbed steel bar, also known as ribbed steel, usually with 2 longitudinal ribs and transverse ribs uniformly distributed along the length. The transverse rib shape is helical, herringbone, crescent 3. Expressed in millimeters of nominal diameter. Nominal diameter of round steel bars of equal diameter equal to the cross section of ribbed bars. The nominal diameter of the steel bar is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32 and 40 mm. Ribbed steel bars are mainly subjected to tensile stress in concrete. Because of the function of rib and the greater bonding ability of concrete, ribbed steel bar can bear the effect of external force better. Ribbed steel bars are widely used in a variety of building structures, especially large, heavy, light, thin-walled and high-rise structures.s
The letters on the reinforcement are registered plant names or trademarks.
