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.

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.

Deformed Steel Bar
Deformed Steel Bar is the surface ribbed reinforcement, also known as ribbed reinforcement, usually with two longitudinal ribs and transverse
ribs evenly distributed along the length direction. The shape of transverse rib is spiral, herringbone and crescent.The production process is as follows: Walking beam heating furnace → roughing mill → intermediate mill → finishing mill → water cooling device →
cooling bed → cold shear → automatic counting device → baler → unloading bench.
Deformed steel bar is commonly known as hot-rolled ribbed steel bar. It belongs to small section steel and is mainly used for the skeleton of reinforced concrete building components. In use, it is required to have certain mechanical strength, bending deformation performance and process welding performance. The raw material billet for the production of rebar is carbon structural steel or low-alloy structural steel treated by sedation melting, and the finished rebar is delivered in hot-rolled forming,normalizing or hot-rolled state.
