High strength planished concrete renforcing bar is the largediameter,high strength precision straight steel bar with male thread on the whole bar.This bar can be connected with the jointer at any cross section or screwed with the nuts with female screw for fixing.
Planished concrete renforcingbar is widely used for large irrgation works,industrial workshops,large and middle bridges lf road and railway,nuclear stations,anchor blocks and so on.Easy to connect and fixe,high abhesivity,safe and reliable to use,convenience to operate,Using them can reduce steel bars,cross area and weight of the stuctural members.
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。
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。
其他具体信息请参阅国家标准《GB/T 20065-2006 预应力混凝土用螺纹钢筋》。
