Sometimes curved steel are a relatively minor part of a structure, e.g. a canopy at the entrance of a high-rise building. Sometimes the curved steel members form a curtain wall encircling an entire arena. And sometimes the curved steel members constitute the trusses for an entire retractable roof of a stadium.

Some architects and engineers think that curved steel adds to the cost of a structure. Of course, a curved beam, for example, includes the cost of bending it and therefore would be more expensive than a straight steel beam. But there are occasions when a curved steel beam would be less expensive than a segmented curve that would require full-penetration welds to achieve a curve. Benders and Rollers, companies that specialize in curving steel, welcome the opportunity to become involved as a steel team member to offer cost-saving solutions for a variety of applications early in a project.
