A profile (1) is produced from a bent metal sheet (2) surrounding an interior space (3) by at least 360°, the longitudinal edges (10, 11) of said metal sheet being connected to respectively adjacent wall sections (4, 6) of the sheet (2). The longitudinal edges (10, 11) are separated from the respectively adjacent wall sections (4, 6) or longitudinal edges (11, 10) by means of spacers (16) and are connected thereto in a form-fitting manner by fasteners (13) such as screws, rivets or the like. |
