Product Description
Professional Production Factory S355J2 20mm Carbon Steel Round Bar
Carbon steel Round bar is divided into three types: hot rolled, forged and cold drawn. The specifications of hot-rolled round steel are 5.5-250 mm. Among them: 5.5-25 mm small round steel is mostly supplied in bundles of straight strips, which are often used as steel bars, bolts and various mechanical parts; round steel larger than 25 mm is mainly used for manufacturing mechanical parts and tube blanks of seamless steel pipes wait.
