A profile bar (10, 10a) formed as an extruded part and consisting of a light metal alloy, in particular an aluminium alloy, with a rectangular in particular square, cross-section, wherein a longitudinal groove pair (20, 20a), comprising two longitudinal grooves arranged parallel to one another and at a distance from one another, is provided in each case on at least one lateral surface, preferably on all four lateral surfaces, and with at least two, preferably four, longitudinal channels which extend parallel to the longitudinal grooves and which form in each case an opening (40) for fastening in each case a pen (34) on each of the two end faces (36) of the profile bar (10, 10a), wherein each longitudinal channel is arranged on an imaginary intersection line of planes extending at a right angle to one another and arranged perpendicularly to in each case a lateral surface, wherein at least one of the planes is a longitudinal centre plane of a longitudinal groove of a longitudinal groove pair (20). |
