The difference between rebar and light round steel: The difference between rebar and light round steel is that there are longitudinal and transverse bars on the surface, usually two longitudinal and transverse bars are evenly distributed along the length direction.

The shapes of the transverse ribs are spiral, herringbone and crescent. It is expressed in millimeters of the nominal diameter. The nominal diameter of the ribbed steel bar is equivalent to the nominal diameter of the smooth round steel bar of equal cross-section.

The nominal diameter of steel bars is 8-50mm, and the recommended diameters are 8, 12, 16, 20, 25, 32, 40mm. Ribbed steel bars are mainly subjected to tensile stress in concrete. Ribbed steel bars have a greater ability to bond with concrete due to the role of ribs, so they can better withstand external forces. Ribbed steel bars are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures.
