Structural shape rolling, also known as shape rolling and profile rolling, is a metal forming process where structural shapes are passed through rollers to bend or deform the workpiece to a desired shape while maintaining a constant cross-section. Structural shapes that can be rolled include: I-beams, H-beams, T-beams, U-beams, angle iron, channels, bar stock, and railroad rails. The most commonly rolled material is structural steel, however other include metals, plastic, paper, and glass. Common applications include: railroads, bridges, roller coasters, art, and architectural applications.
It is a cost effective way of bending this kind of material because the process requires less set-up time and uses pre-made dies that are changed out according to the shape and dimension of the workpiece. This process can roll workpieces into full circles.

Famous quotes containing the words structural, shape and/or rolling:
“The reader uses his eyes as well as or instead of his ears and is in every way encouraged to take a more abstract view of the language he sees. The written or printed sentence lends itself to structural analysis as the spoken does not because the reader’s eye can play back and forth over the words, giving him time to divide the sentence into visually appreciated parts and to reflect on the grammatical function.”
—J. David Bolter (b. 1951)
“The “universal moments” of child rearing are in fact nothing less than a confrontation with the most basic problems of living in society: a facing through one’s children of all the conflicts inherent in human relationships, a clarification of issues that were unresolved in one’s own growing up. The experience of child rearing not only can strengthen one as an individual but also presents the opportunity to shape human relationships of the future.”
—Elaine Heffner (20th century)
“The Concord had rarely been a river, or rivus, but barely fluvius, or between fluvius and lacus. This Merrimack was neither rivus nor fluvius nor lacus, but rather amnis here, a gently swelling and stately rolling flood approaching the sea. We could even sympathize with its buoyant tied, going to seek its fortune in the ocean, and anticipating the time when “being received within the plain of its freer water,” it should “beat the shore for banks.””
—Henry David Thoreau (1817–1862)
