Roll forming is a metal fabricating process where sheet or coil stock metal is continuously bent and shaped with a series of rollers until the desired cross-sectional profile is obtained. Frame roll forming machines are used to create frame and structural components with complex long length profiles by progressive rolling, cutting and welding from metal coils.
Frame roll forming provides an efficient, economical and flexible way to manufacture metal framing with customized dimensions and geometries compared to other fabrication processes. This guide provides a detailed overview of various aspects of frame roll forming technology and machines.
