Rolling operations are metal forming processes where metal is passed through rollers to reduce thickness, change shape, or improve mechanical properties using compressive force. It is widely used to produce products such as sheets, plates, bars, rods, and structural shapes.
Rolling can be done as hot rolling (for large deformation and shaping) or cold rolling (for better surface finish, accuracy, and strength). These processes are important in manufacturing industries because they support mass production of strong, uniform, and high-quality metal products used in construction, automotive, and engineering fields.
