Product Description
Round steel is divided into three types: hot rolled, forged and cold drawn. The 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.
