Abstract
In a method of using a closed, extruded profile, developing a hollow profile and producing a stepped cross-sectional metal sheet with different wall thicknesses, the profile or the hollow profile is used as a starting material for rolling. The hollow profile has only one wall, which turns back in on itself in the peripheral direction without branching and is of different thicknesses at different points of the periphery. The hollow profile is separated along a surface line, is formed into the semifinished article and is subsequently rolled to produce the metal sheet.
