Cold roll forming is a process of forming metal from sheet, or coiled stock, into shapes of uniform cross-section, generally by feeding the stock longitudinally through successive pairs of rolls, each pair of rolls progressively forming the stock until the finished cross- section is produced. The principal advantage of cold roll forming, as compared with other methods of fabrication, is high production capacity. The review writes the investigation results of production rates of many shapes formed by cold roll forming equipment in past thirty years, and also, how to determine the optimum number of roll station, the optimum distribution of bend angle to form the shape. The mechanism of shape defect such as pocket wave, twist, and distortion near cut-off edge are explained. The flexible cold roll forming stand which can form the new shape with un-uniform cross section, is introduced.
