Abstract (en)
[origin: WO2020149752A1] A section according to the invention with a dual-plane bend of flanges provides formation of a dilatation slit in part of a sheathing supporting area against the flange, which necessitates an advantageous transfer of location of the forces transmitted at the contact point beyond the dilatation slit area, towards the centre of the flange, eliminating beam torsion. The Z-section is formed of a web (1) with two flanges (2 and 3) with an edge stiffener (4). At least one of the Z-section flanges has a dual-plane bend in a form of an off+set (5) or fold (11), dividing thereof into a lower portion (6, 12) located at the web (1) and an upper portion (7) at the edge stiffener.
