The difference between rebar and round bar and rebar distinction plain bars is a surface with longitudinal ribs and transverse ribs, usually with two road along the longitudinal direction of the longitudinal ribs and transverse ribs evenly distributed. Rebar is a small steel steel, mainly for the skeleton of reinforced concrete building elements. In use, it requires a certain degree of mechanical strength, bending welding performance and process performance. Production of steel billets as raw material through carbon steel or low-alloy structural steel, finished steel smelting process of calming hot-rolled forming, normalizing or hot-rolled delivery. Properties and Uses widely used in civil engineering construction of buildings, bridges, roads and the like. Great to highways, railways, bridges, culverts, tunnels, flood control, dams and other public facilities, housing construction on the basis of small, beams, columns, walls, slabs, steel structural materials are essential. With the degree of urbanization of the deepening, infrastructure construction, real estate booming strong demand for rebar.
