[0002] Steel refers to steel for reinforced concrete and prestressed reinforced concrete, which has a circular cross section, sometimes a square with rounded corners, including plain round steel, ribbed steel and twisted steel; steel for reinforced concrete refers to straight or coil steel for reinforced concrete reinforcement, which is divided into plain round steel and deformed steel, and is delivered in straight and coil forms. Plain round steel is actually small round steel and coil round steel made of ordinary low carbon steel; deformed steel is ribbed steel, usually with two longitudinal ribs and evenly distributed transverse ribs along the length. Deformed steel has better adhesion to concrete due to the ribs, so it can better withstand external forces. Steel is widely used in various building structures, especially large, heavy, light, thin-walled and high-rise building structures.
