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: 20MnSi, 20MnV, 25MnSi, BS20MnSi. 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.

Round steel is divided into three types: hot rolled, forged and cold drawn. The specifications of hot-rolled round steel are 5.5-250 mm. Among them: 5.5-25 mm small round steel is mostly supplied in bundles of straight strips, which are often used as steel bars, bolts and various mechanical parts; round steel larger than 25 mm is mainly used for manufacturing mechanical parts and tube blanks of seamless steel pipes wait.

Channel steel is a long strip of steel with a groove-shaped cross-section. It belongs to carbon structural steel for construction and machinery. It is a section steel with a complex cross-section. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.
