Abstract
A bumper beam and method of manufacture which includes roll-forming the bumper beam with a constant longitudinal cross section, and then reforming the roll-formed beam to form a tubular bumper beam having a constant area. The bumper beam area is designed to incorporate a longitudinal “curvature” to form angular surfaces consistent with many modern automobile fascias, thereby, enabling high impact absorption efficiency.
