At its core, a metal roll former operates by feeding a flat metal strip through a series of rollers, each designed to gradually alter the shape of the strip. The process begins with a carefully prepared set of rollers, which are configured to achieve the desired cross-section of the final product. As the metal sheet moves through the machine, each set of rollers adds incremental changes, leading to a final product that can range from simple angle shapes to complex profiles like Z- or C-frames.
