The diameter of the steel bar is 8-50 mm, the recommended diameter is 8, 12, 16, 20, 25, 32, 40 mm. Steel grade :20MnSi,20MnV,
25MnSi, BS20MnSi. Reinforcement in concrete is mainly subjected to tensile stress. Due to the effect of the rib, the deformed
steel bar has greater bonding ability with the concrete, so it can bear the effect of external forces better. Steel bars are
widely used in all kinds of building structures. Especially large, heavy, light thin-walled and high-rise building structures.

Rebar is a surface ribbed bar, also known as ribbed bar, usually with two longitudinal ribs and transverse ribs evenly distributed along the length direction. Transverse rib shape for spiral, herringbone, crescent shape 3 kinds. In millimeters of nominal diameter. The nominal diameter of ribbed bars is equivalent to the nominal diameter of a circular bar with the same cross section. The nominal diameter of the steel bar is 8-50 mm, the recommended diameter is 8, 12, 16, 20, 25, 32, 40 mm. Ribbed bars in concrete are mainly subjected to tensile stress. Due to the action of the rib, the ribbed steel bar has greater bonding ability with the concrete, so it can bear the effect of external forces better. Ribbed steel bars are widely used in a variety of building structures, especially large, heavy, light thin-walled and high-rise building structures.
