Steel coil slitting is the process of cutting a master coil of steel into several narrower coils, each with consistent width and edge quality. The operation is performed by a coil slitting line, which uncoils, slits, and recoils the material in one continuous process.The goal is to prepare steel strips of required widths for downstream operations such as tube making, roll forming, stamping, or fabrication. This process optimizes material usage, minimizes waste, and increases production flexibility.
