The present invention relates to a method for producing a lightweight sheet-metal component with varying wall thicknesses, characterized by the following method steps: —extruding a lightweight metal to form a profile with a non-planar profile cross section, wherein the wall thicknesses of the profile cross section differ from one another in at least two regions, —cutting the profile to length into profile pieces, —widening the profile pieces, —forming the flattened profile piece into a three-dimensional shaped sheet-metal component, wherein the sheet-metal component has at least two regions with wall thicknesses that are different from one another.
