ComFlor® 225
Deep composite profile
Developed specifically for Corus Slimdek® system, ComFlor® 225 offers up to 6.5 metres umpropped span. Corus Slimdek® engineered flooring solution is a unique structural floor system which uses Asymmetric SlimFlor Beams, where the bottom flange is wider than the top flange. The ComFlor® 225 steel deck bears on the lower flange of the beam which results in a minimal overall floor depth, the concrete that surrounds the the beams provides composite action wtihout the need for shear studs, and fire protection to the beam. The Slimdek® system is fast, eliminates temporary props, is structurally optimised and saves on cladding costs. The system also reduces building height or enables extra floors to be built.
