FIELD: construction.
SUBSTANCE: beam for a suspended ceiling is formed of a metal strip folded along its length. Section of the beam profile has a bulge in the upper part, a vertical single-layer wall and two shelves. The first shelf horizontally diverges in the form of a cantilever from the lower part of a wall in the first direction. The second shelf horizontally diverges in the form of a cantilever from the first shelf in the second direction, which is opposite to the first direction. The second shelf is fixed to the first shelf by means of a seam arranged along the wall. The first and second shelves diverge in the form of cantilevers from the wall with the possibility of balancing load onto the beam in the suspended ceiling and its application in the wall plane.
EFFECT: reduced metal intensity.
