Abstract: The invention relates to a method for producing a bent torsional profile comprising the following process steps: a) provision of a plate made of planar sheet metal, b) reshaping of the plate through the introduction of a bent trough oriented in the longitudinal direction of the plate in a central length portion (6) of the plate at a distance from the front edges of the plate, forming legs between the trough and the longitudinal edges of the plate, c) reshaping of the legs in such a manner that an open profile is created, d) reshaping of the legs in such a manner that a hollow profile is produced, wherein a longitudinal gap is formed between the two legs over the entire longitudinal extent thereof and wherein an air gap is created between the legs and the trough in the region of the trough, e) joining of the two legs over the entire longitudinal gap.
