圓鋼是指截面為圓形的實心長條鋼材。其規格以直徑的毫米數表示，如“ 50”即表示直徑為 50毫米的圓鋼。
Forged round is a round steel that has been forged by the process. Specifications domestic general production can reach 1500mm diameter. Forgings are forged and impact, suitable for small parts or profiled steel.
Round steel is a solid strip of steel with a circular cross section. The specifications are expressed in millimeters of diameter. For example, "50" means a round steel with a diameter of 50 mm.
Round steel is divided into hot rolling, forging and cold drawing. Hot rolled round bars are available in sizes from 5.5 to 250 mm. Among them: small round steels of 5.5-25 mm are mostly supplied in straight strips, often used as steel bars, bolts and various mechanical parts; round steels larger than 25 mm are mainly used for manufacturing mechanical parts or seamless steel tube blanks.
