A roll forming machine accomplishes the fabrication process by sending sheet metal through a series of fixed rollers, which continuously and incrementally bend the metal into the required form. By progressively bending the metal bit by bit at strategically spaced rollers, manufacturers can customize cross-sectional shapes with exacting precision and uniformity. A typical speed for roll forming machines is anywhere from 30 to 100 feet of metal per minute, ensuring an incredible ongoing output of material.

As a leading roll forming machine manufacturer, PUTAI has designed and built roll forming machines for roofing sheet, wall cladding, steel purlins, metal decking, guard rails, lightweigth steelframes, steel windows and door components, steel pipes, and many other custom profiles.
