Product Description

Round steel is a hollow cylindrical metal material, which is widely used in construction, machinery manufacturing, automobile manufacturing, energy, transportation and other industries. Round steel is made in a variety of processes, including hot rolling, cold drawn manufacturing and cold drawn manufacturing.Carbon round steel is a solid length of steel with a round cross-section, which is used to manufacture machine parts or as seamless steel pipe billets.
