Everything about steel bars!
Steel bars for reinforced concrete refer to straight steel bars or rolled steel bars used to strengthen reinforced concrete. Its shape is divided into smooth round ribs and special-shaped ribs, and the delivery state is straight and.

There are two kinds of CDs. Smooth round steel is actually a small round steel and coil of ordinary low carbon steel. Deformed steel bars are steel bars with ribs on the surface, usually with two longitudinal ribs and transverse ribs evenly distributed along the length. The shapes of transverse ribs are spiral, herringbone and crescent. Expressed in millimeters of nominal diameter. The nominal straight diameter of deformed steel bar is equivalent to the nominal diameter of smooth round steel with equal cross section. The nominal diameter of reinforcement is 8-50mm, and the recommended diameters are 8, 12, 16, 20, 25, 32 and 40m.

Steel bars mainly bear tensile stress in concrete. Deformed steel bars have great bonding ability with concrete due to the action of ribs, so they can better withstand the action of external forces. Steel bars are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures.
