Abstract: A composite construction which has a beam part (1) and a slab part (2) bearing thereon, the construction comprising the following components: a) a metal mantle (3) of the beam part, the mantle being at the same time the casting form and being made up of an upwardly open profile; b) additional reinforcement components (7) which, together with the metal mantle, make up the reinforcement of the composite construction; and c) a cast component (8) which, when set and together with the metal mantle and with the additional reinforcement components left inside the casting, makes up the composite construction. The metal mantle (3) of the beam part (1) is a shaped profile the inner surface (10) of which has an embossed pattern.
