The difference between rebar and polished bar is that the surface has longitudinal and transverse ribs, usually with two longitudinal ribs and transverse ribs that are evenly distributed along the length. Rebar is a small steel steel, mainly used for the skeleton of reinforced concrete building components. In use requires a certain degree of mechanical strength, bending deformation and process welding performance. Raw material billet for rebar production is carbon structural steel or low-alloy structural steel that is smelted and smelted, and finished steel products are delivered in hot-rolled, normalized, or hot-rolled state.
The rebar steel bar has its finest English Fine (Fine) first letter followed by the abbreviation of the hot-rolled ribbed bar. Such as: HRBF335, HRBF400, HRBF500. The higher-required anti-seismic structure is available in the following grades: E is added to existing grades (eg, HRB400E, HRBF400E).
Main uses: Widely used in civil engineering projects such as houses, bridges and roads.
The main origin: The production of rebar is mainly distributed in China's North China and Northeast China, North China, such as Shougang, Tangshan Iron and Steel, Xuanhua Steel, Chenggang, Xinxing Casting Pipe, Shanxi Zhongyang Steel Plant, Baoding Puri Steel, etc. In areas such as Jianlong, Xilin, Beitai and Fushun, these two regions account for more than 50% of the total rebar output.
