[0002] Rebar refers to the steel used in reinforced concrete and prestressed concrete. Its cross-section is typically circular, primarily bearing tensile stress. The ribs provide a strong bond with the concrete, allowing it to better withstand external forces. Rebar is widely used in various building structures, particularly large, heavy, lightweight, thin-walled, and high-rise buildings. During use, rebar often requires bending according to requirements. On construction sites, bending devices are typically portable and user-friendly bending tools.
