FIELD: construction.
SUBSTANCE: invention relates to construction and can be used as beam elements of buildings. H-shaped curved closed profile of two flat belts and two perforated walls of channel-shaped form, attached to belts by means of toothed engagements of longitudinal edges of horizontal sections and mutually resting on vertical sections, perforated walls along entire length of vertical sections are provided with cutouts with toothed engagements of edges along the entire perimeter of each of said cutouts. Overall height exceeds that of its width by 3 to 4 times, when height of cuts makes 0.7–0.8 of profile height, and by 5.9–6 times when height of cuts makes 0.1–0.2 of profile height.
EFFECT: technical result is sufficient local and general stability of H-shaped curved closed profiles from plane and in plane of bearing structure.
