Roll forming, also spelled??roll-forming??or??rollforming, is a type of??rolling??involving the continuous??bending??of a long strip of??sheet metal??(typically coiled??steel) into a desired cross-section. The strip passes through sets of rolls mounted on consecutive stands, each set performing only an incremental part of the bend, until the desired cross-section (profile) is obtained. Roll forming is ideal for producing constant-profile parts with long lengths and in large quantities.
