Type of Sub-products

Hot Rolled Round Bar Hot Rolled Round Bar
Hot rolled round bars are manufactured at high temperatures, resulting in a rough surface finish and less precise dimensions. These bars are ideal for structural applications, general fabrication, and industrial use where high strength is required but tight tolerances are not critical.

Cold Rolled Round Bar Cold Rolled Round Bar
Cold drawn round bars are processed at room temperature, offering a smooth finish, greater dimensional accuracy, and improved mechanical properties. They are commonly used in precision components, shafts, and machinery parts where tight tolerances and superior surface quality are important.
