Sedvik industries manufactures offers the complete range of universal type roll forming machines for forming coiled strip as well as sheet metal. The process involves progressively forming metal strip in coil or sheet form to the ultimate desired shape by feeding the stock through a series of contoured roller dies. Because the sections could be shaped in such a way that high strength-to-weight ratio is obtained, ccold roll formed sections can save up to 50% in steel consumption as compared to conventional hot-rolled sections. By going in for closed hollow sections of the required shape, further increase in strength-to-weight ratio could be achieved. Cold roll forming is a high-output, low-material-consumption technological process. With these roll forming machines, metal sections can be formed to close dimensional tolerances to any transportable length while obtaining straightness with repeatable accuracies and a high quality finish. Coated strips like painted or galvanised sheets as well as stainless steel, copper and aluminium strips could be easily roll formed to the required shapes and finish.
