A novel composite floor system is described, together with a specific metallic reinforcing and support section for use in the floor system. The system comprises a concrete slab and a metallic reinforcing and support section mechanically embedded in the slab. The support section comprises an elongated unitary strip having a substantially flat central web portion containing a plurality of spaced holes, a pair of substantially flat leg portions extending away from the sides of said web and an edge flange extending outwardly from the outer end of each leg portion, with at least the leg portions and the edge flanges being embedded in the concrete with the web adjacent the face of the slab. Support bolts are mounted within the web portion holes and extend outwardly from the slab. These bolts can be used to support a formwork for the pouring of the concrete slab.
