1. OVERVIEW OF DEFORMED STEEL BARS

Rebar, also known as ribbed steel bars, usually with two longitudinal ribs and transverse ribs which evenly distributed along the length. The common shape of transverse rib are  helical, herringbone, crescent-shaped. The nominal diameter of rebar is 8-50 mm. Rebar is widely used in civil construction, bridges, roads, railways, culverts, tunnels, flood control project, dams and other public facilities. Rebar is the primary reinforcing material in reinforced concrete.
