Abstract
The present invention refers to a procedure for manufacturing a tubular sheet metal beam having corbelled-out end sections, preferably intended to form part of a vehicle body, and a sheet metal beam manufactured according to the procedure. To simplify and cut the cost of manufacturing stiffened, tube-shaped beams with corbelled-out end sections for welding, it is suggested according to the invention that the beam is partly or wholly provided with concertina-like wave-shaped profiles (9) with a series of alternating valleys (10) and peaks (11) running in the longitudinal direction of the beam and that these wave-shaped profiles form an excess of material that is used in a subsequent corbelling-out operation of the end sections (12) of the beam.
