Abstract: An upright section having two section legs extending spaced from each other in the longitudinal direction of the section and connected with each other by a section bridge. The section bridge is equipped with at least one elastic segment having low transverse spring temper and extending in the longitudinal direction of the section. The elastic segment is shaped out of the plane put up by the section bridge and connects the section legs with bending elasticity. Since the section bridge is equipped with at least one elastic segment extending lengthwise, the upright section is divided in two section parts that are connected with each other only via the elastic segment arranged between the two parts.

Abstract: In a lightweight longitudinal angled section, particularly a cover-carrying profile, which includes two legs spaced from one another extending along the longitudinal direction, wherein a longitudinal bar connects the legs, and each leg is formed with stiffening devices, which, in turn, include at least one longitudinal impression, each leg has a free longitudinal end facing away from the bar, and wherein the free longitudinal end is formed with a longitudinal flange extending approximately parallel with the bar so as to face inwardly, the improvement includes longitudinal edge portions connecting respective legs to the bar, corrugations which extend transverse to the longitudinal direction along each leg up to the longitudinal impressions, and therebeyond to the longitudinal edge portions, and at least partly over a portion of the width of the bar, and wherein the corrugations are spaced from one another at substantially identical distances.
