Product  Description


Round steel is a long strip of steel with a solid cross section. Its specifications are expressed in millimeters in diameter. They are divided into three types: hot-rolled, forged, and cold-drawn. The hot-rolled specifications are 5.5-250 mm. They are often used as steel bars, bolts, and various Mechanical parts, round steel larger than 25 mm is mainly used to manufacture mechanical parts and seamless steel tube billets.
