Rebar is a common name for hot-rolled ribbed steel bars. The grade of ordinary hot-rolled steel bar is composed of HRB and the minimum yield point of the grade. H, R, and B are the English initials of the three words Hotrolled, Ribbed, and Bars, respectively. The hot-rolled ribbed steel bars are divided into two grades: HRB335 (the old brand is 20MnSi), HRB400 (the old brand is 20MnSiV, 20MnSiNb, 20Mnti), and HRB500, the fourth grade.
Deformed bars are ribbed bars on the surface, usually with 2 longitudinal ribs and transverse ribs evenly distributed along the length. The shape of the transverse rib is spiral, herringbone and crescent.

Deformed Steel Rebars
Rebar is a common name for hot-rolled ribbed steel bars. The grade of ordinary hot-rolled steel bar is composed of HRB and the minimum yield point of the grade. H, R, and B are the first letters of the three words: Hotrolled, Ribbed, and Bars respectively. Rebar is a ribbed steel bar on the surface, also known as ribbed steel bar, usually with two longitudinal ribs and transverse ribs evenly distributed along the length. The shape of the transverse ribs is spiral, herringbone, and crescent. It is expressed in millimeters of the nominal diameter. The nominal diameter of ribbed steel bars is equivalent to the nominal diameter of smooth round steel bars with equal cross-sections. The nominal diameter of the steel bars is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32, and 40 mm. Ribbed steel bars mainly bear tensile stress in concrete. Ribbed steel bars have greater bonding capacity with concrete due to the action 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.
