VST-beams consist of three cement-bonded particle boards, which are connected to each other by angles. The reinforcement can already be installed in the factory. The dimensions of the VST-beams are freely selectable. On site, the beams are fastened to the adjacent slab elements and concreted out, whereby the concrete bonds with the cement-bonded particle board.
VST-beams have fire protection class A2-s1, d0.
