Rebar refers to steel for reinforced concrete and prestressed reinforced concrete. Its cross-section is circular and sometimes square with rounded corners. Including Round Steel bars, ribbed steel bars, and torsional steel bars. Reinforced concrete refers to straight strips or strip-shaped steel used for reinforced concrete reinforcement. Its appearance is divided into two types: round steel bars and deformed steel bars, and the delivery status is straight strips and round bars. The round steel bars are actually small round steel and disc round of ordinary low carbon steel. Deformed steel bars are ribbed steel bars on the surface, usually with 2 longitudinal ribs and transverse ribs evenly distributed along the length direction. The shapes of the horizontal ribs are spiral, herringbone, and crescent. Denoted by millimeters of nominal diameter. The nominal diameter of the deformed steel bar is equivalent to the nominal diameter of the light circle steel bar with equal cross-sections. The nominal diameter of steel bars is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32, 40 mm. Steel type: 20MnSi, 20MnV, 25MnSi, BS20MnSi. Rebars mainly bear tensile stress in concrete. Due to the action of the ribs, deformed steel bars have a greater bonding ability to concrete, so they can better withstand the effects of external forces. Rebar is widely used in various building structures. Especially large, heavy, lightweight thin-walled and high-rise building structures.
