Fundamentally cold roll forming is defined as a continuous, high-volume, fabricating process in which a desired shape is formed from a flat strip of metal by passing it through a series of matching pairs of contoured rolls. Only bending occurs in the roll process and does not change the thickness of the metal except for a slight thinning at a bend radius. Roller forming is a continuous process that is extremely economical and efficient particularly when the job requires shaping sections into extended lengths at high volume.
