Steel rebar are mainly subjected to tensile stress in concrete. The deformed steel bar has a greater bonding ability with concrete due to the action of the ribs, and thus can better withstand the external force. Rebar is widely used in various building structures. Especially large, heavy, lightweight thin-walled and high-rise buildings.
