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.

Vehicle bumper beam
A bumper beam includes an open front section made from a high-strength material such as ultra-high-strength steel (UHSS) material, and further includes a mating back section made of lower-strength material attached to a rear side of the front section along abutting flanges. The front and back sections combine to define different tubular cross sections. The front section can be roll-formed, and the back section can be stamped, thus taking advantage of roll-forming processes' ability to form high-strength materials, while allowing the back section to have a more complicated shape and be stamped. The abutting flanges telescopingly overlap in a fore-aft direction of the vehicle and are welded together at locations that potentially experience shear upon impact, but the flanges of the front section are captured within the flanges of the backs section, thus providing impact strength even if the attachment locations shear off.
