The nominal diameter of the steel bar is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32, 40 mm. Steel types: HRB 335 HRB 400 HRB 400 e HRB 500 HRB 500 e。 Steel bars mainly bear tensile stress in concrete. Due to the effect of the ribs, the deformed steel bar has a greater bonding capacity with the concrete, so it can better withstand the external force. Steel bars are widely used in various building structures. Especially large, heavy, light thin-walled and high-rise building structures.
