What are the common diameters of steel bars?
Round bar is in fact the ordinary low carbon steel small round and round. Deformed steel bars are ribbed steel bars, usually with 2 longitudinal ribs and transverse ribs uniformly distributed along the length. The transverse rib shape is helical, herringbone, crescent 3. Expressed in millimeters of nominal diameter. The nominal diameter of deformed steel bar is equal to the nominal diameter of the round steel bar of equal cross section. The nominal diameter of the steel bar is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32 and 40 mm. Steel grades: 20MnSi, 20MnV, 25MnSi, BS20MnSi. Steel bars are mainly subjected to tensile stress in concrete. Because of the function of rib and the greater bond ability of concrete, deformed steel bar can bear the effect of external force better. Reinforcement is widely used in various building structures. Especially large, heavy, light, thin-walled and high-rise structures.
Steel bars for concrete reinforcement is straight or strip steel plate reinforced concrete reinforcement steel, its shape is divided into round steel bar and deformed steel two, straight and coiled state for delivery two.
Rebar common diameter 6, 6.5, 8, 12, 14, 16, 18, 20, 22,, 25, 28, and 32.Reinforced concrete (Rebar) is used for reinforced concrete and prestressed reinforced concrete steel, its cross section is round, sometimes with rounded square. Including round steel bar, ribbed steel bar and twisted steel bar.
