Abstract
A hollow profile bar, preferably of extruded metal, comprises a tubular wall that is equally thick all around and is provided with salient outer webs evenly distributed about the outer circumference, which in pairs form undercut casing grooves with side walls, a radial salience of the outer webs from the tubular wall being substantially equal to the thickness of the tubular wall. To achieve tight packing of profile bars that are to be connected in one sectional plane of a hollow profile bar, the hollow profile bar is configured in such a way that slope lines of the side walls of an outer web intersect between the outer web and the axis of the bar.
