The rebar can be used to unscrew the connector of the internal thread (the fine rolling screw steel connector) and screw the threaded nut (the fine rolled nut) with the screw in any section of the section. 精轧螺纹钢筋以屈服强度划分级别，其代号为“PSB”加上规定屈服强度最小值表示。常用级别为： PSB500、PSB785、PSB830、PSB930、PSB1080 The fine rolled steel bars are rated at the yield strength level, whose code is "PSB" and the minimum yield strength is indicated. Commonly used level: PSB500, PSB785, PSB830, PSB930, PSB1080
精轧螺纹钢筋的公称直径范围为18mm~50mm，一般推荐的公称直径为25mm、32mm。 The nominal diameter of the fine rolled steel bars is 18mm~ 50mm, and the nominal diameter is 25mm and 32mm.
精轧螺纹钢筋的外观尺寸符合交通部门公路规划设计院预应力高强度精轧螺纹粗钢筋外形及尺寸规定。外形为等高肋。常规定尺长度为9米和12米，也可根据用户需要商定定尺长度。可做到每捆定支数小捆重包装并按负偏差交货。 The dimensions of the fine rolled steel bars are in ordance with the shape and size of the rough bars of the high strength precision rolled thread of the highway planning and design institute of the transportation department. The contour is equal to the ribs. It can be used for each bundle of fixed number of small bundles to be repackaged and delivered ording to the negative deviation.
