I Main rebar wire, major brands Shougang steel, Tang steel rebar, Xuanhua Steel rebar, bearing steel rebar, is of first Tang Xuancheng four steel mills in North China distributor, the annual sales volume of 15 million metric tons, the Wuqing District the rebar spot consulting 022-596960552,18622303953, may enter into the purchase contract, provide quality assurance Rebar is commonly known as hot-rolled ribbed steel bars. Ordinary hot-rolled steel grades by the HRB and grades yield point constitute a minimum. H, R, B, respectively hot rolled (Hotrolled), ribbed (Ribbed), English first letter of the three words reinforced (Bars). Rolled ribbed steel bars the divided into HRB335 (the veteran No. 20MnSi), HRB400 (veteran for 20MnSiV and 20MnSiNb 20Mnti) of HRB500 three grades. The main purpose of the rebar is used in the beams and pillars of the important buildings and bridges. Above the rib when combined with some more solid round steel and concrete pouring! Rebar is used primarily in the construction industry, and machinery, light industry, automobile industry, the relative construction industry, it is necessary to small lot. The difference: the difference between rebar and plain bars of rebar and plain bars surface with longitudinal ribs and transverse ribs, usually with two longitudinal ribs and transverse ribs evenly distributed along the length. It belongs to a small section of steel rebar, mainly used in reinforced concrete skeleton of the building components. In use requires a certain degree of mechanical strength, bending deformation properties and process welding performance. Raw billet production of rebar by sedation smelting process carbon structural steel or low-alloy structural steel, finished steel bar for hot-rolled forming, normalizing or hot-rolled state Delivery.
