Reinforcement refers to steel for reinforced concrete and prestressed reinforced concrete, which is circular in cross-section and sometimes square with rounded corners. Including plain round bars, ribbed bars, twisted bars. There are many types of steel bars, usually classified by chemical composition, production process, rolled shape, supply form, diameter, and use in structures. The steel bar for reinforced concrete refers to the straight or coiled steel used for reinforced concrete reinforcement, and its shape is divided into two types: smooth round steel bar and deformed steel bar. 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 action of external forces
