At its core, roll forming involves feeding a long strip of metal (usually steel) through a series of rollers, each progressively shaping the metal into a specific profile. The process starts with a flat sheet of metal, which moves through multiple stations where it is gradually bent and shaped until the desired form is achieved. This method is favored for its efficiency, ability to produce complex shapes, and minimal waste generation compared to other manufacturing processes like stamping or machining.
