Product Description
Steel Round Bar Q235 Q345 Ss400 Low Carbon Mild Steel Round Bar
Carbon Steel Round Bar 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.
