Hot Sale HRB400 HRB500 Coiled Reinforcing Bar Rebar In Coil

Rebar is a steel bar with ribbed surface, also known as ribbed steel bar, usually with 2 longitudinal ribs and horizontal ribs evenly distributed along the length direction. The shape of the transverse rib is spiral shape, herringbone shape and crescent shape. Expressed in millimeters of nominal diameter. The nominal diameter of a ribbed bar is equivalent to the nominal diameter of a circular bar of equal cross-section. The nominal diameter of the steel bar is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32, 40 mm. Ribbed steel bars bear mainly tensile stress in concrete. Ribbed steel bars have greater bonding capacity with concrete due to the role of ribs, so they can better withstand the action of external forces. Ribbed steel is widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures.
