FIELD: building, particularly profiled beams to construct floor coverings with thickness of 25 - 40 mm for arranging finishing floors and other structures, for instance for flat roofs.
SUBSTANCE: profiled beam comprises longitudinal load-bearing member, two perforated side walls connected with bearing member and perforated bases extending from them in opposite directions. Each base has bent end forming longitudinal three-edged extension. The first edge is perpendicular to the major part of base. The second edge is parallel to the second one, the third extreme edge forms an angle of not less than 90o with the second one.
EFFECT: improved cohesion ability between beam and covering material.
