Carbon steel cold rolled coil is produced by further rolling hot-rolled steel coils at room temperature, resulting in high thickness precision, smooth surface finish, and excellent dimensional stability. Compared with hot-rolled coils, cold-rolled coils offer higher strength, better surface quality, and superior formability.
Carbon steel cold rolled coils are widely used in home appliances, automotive, construction decoration, machinery manufacturing, and precision equipment. They are suitable for making sheets, pipes, profiles, and various stamped components.
Carbon steel hot rolled coil is produced by continuously rolling steel billets at a temperature above the recrystallization point, resulting in high strength and good ductility. Hot rolled coils have a relatively rough surface but offer a wide thickness range, making them suitable for various industrial applications.
Carbon steel hot rolled coils are widely used in construction, machinery manufacturing, automotive parts, pipe production, and shipbuilding. They serve as the basic material for making steel sheets, profiles, pipes, and structural components.
