摘要
In a method of making a steel crossbeam for use as component of a bumper for motor vehicles, a composite element is formed by attaching sheet metal strips in parallel disposition onto a broadside of a steel sheet strand across an entire length thereof, whereby the sheet metal strips have a width which is narrower than a width of the steel sheet strand. The composite element is then shaped through roll-forming in a direction transverse to the longitudinal extent of the composite element into a crossbeam.
