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.

carbon steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.
