<p>The hollow profile (1) for an assembly system consists of a flat material of defined thickness (d), and has a crease (6.1,6.2,7.1,7.2) formed in at least one side wall (2.1,2.2,5.1,5.2). The depth (t) of the crease lies within the region of 0.5 to 2.0 times the material thickness and preferably less than 1.5 times the material thickness. The walls (13.1,13.2) of the crease are orientated perpendicularly to the base (8.1,8.2,9.1,9.2) of the crease and flat in construction. An independent claim is included for a method for the manufacture of a hollow profile.</p> |
