Rebar is a common name for hot-rolled ribbed steel bars. The grade of ordinary hot-rolled steel bar consists of HRB and the minimum yield point of the grade. H, R, and B are the initials of three words: Hotrolled, Ribbed, and Bars. Reinforcing bars are ribbed steel bars on the surface, also known as ribbed steel bars. Usually, there are two longitudinal bars and transverse bars evenly distributed along the length. The shapes of transverse ribs are spiral, herringbone and crescent. It is expressed in millimeters of nominal diameter.
