Roll forming is a continuous bending operation in which a long strip of metal—often coiled—passes through consecutive pairs of rolls, each performing incremental bends. This method produces various profiles, such as metal roofing sheets, wall panels, and structural components. Traditionally, roll forming required large, stationary machines, best suited for high-volume production in manufacturing facilities. However, the advent of portable roll forming machines has significantly changed this landscape.
