Abstract
A strengthening member consisting essentially of a bent sheet metal channel with opposing side walls which are provided with stiffening profiling. The profiling forms a uniform pattern of closely spaced indentations (6) separated by intermediate surface regions (7), which pattern extends along each channel wall (2), both the indentations (6) and the intermediate surface regions (7) extending over the entire height of the wall. The channel has a bottom interconnecting the side walls, the indentations having, in a direction parallel to the associated side wall (2), open bases at the bottom and closed apices at upper edges (5) of the walls. The intermediate surface regions (7) have, in a direction parallel to the associated side wall (2), open bases at the upper edges (5) and closed apices at the bottom.
