Description
Different types of steel (different chemical compositions) are used. Reinforcing bars are low-alloy steels; HRB335 grade steel is 20MnSi (20 manganese silicon alloy); HRB400 grade steel is 20MnSiV, 20MnSiNb, or 20MnTi, etc. Reinforcing bars have spiral ribs on their outer surface.
The main function of reinforcing bars is to improve the tensile strength and ductility of concrete members, making them more resistant to earthquakes, cracks, and deformation. At the same time, reinforcing bars can also connect concrete members, improve the strength of the members, and control crack propagation.
Reinforcing bars are generally divided into two categories: ordinary reinforcing bars and high-strength reinforcing bars. The difference between the two lies in their tensile strength and yield strength.
