Abstract
Elongated structural components having regions of different thicknesses, especially for use in automobile bodies, are produced by flexible rolling metal strip so as to form along a length thereof rolled-strip segments of different wall thickness. The sheet bars are cut from the rolled strip and have regions of different wall thickness. Each sheet bar is reshaped in at least one hot-forming tool in at least one hot-forming state and the reshaped sheet bar is then rapidly cooled in the hot-forming tool of the last reshaping stage.
