specification of hot-rolled round steel is 5.5-250mm. Among them:
5.5-25mm small round steel is mostly supplied in straight bars,
which are often used as steel bars, bolts and various mechanical
parts; round steel larger than 25mm is mainly used to manufacture
mechanical parts and seamless steel pipe billets.
