Composite structural floor COMFLOR® 51+

steel

Contemporary new design of the original British re-entrant profile ComFlor® 51+ is a completely new profile that is the latest evolution of a long line of re-entrant profile design, the favoured profile shape for a vast number of projects in Britain since the 1970s. Key benefits are: Fire resistance and flat soffit Slab and beam performance Service attachment Virtually flat soffit: For a clean aesthetic appeal. Composite performance – floor slab: New embossments on ComFlor® 51+ give even better shear key. Composite performance – beam: The classic re-entrant profile shape provides the most effective shear stud performance of all composite profiles. Fire performance: The low intrusion of the re-entrant profile into the concrete allows a good fire rating from a relatively slim slab. The flat soffit provides excellent fire protection to the top flange of the beam. Easy attachment for services: Dovetail grooves at 150mm centre offer the best possible anchorage for services underneath. Notes 1. Deck and beam deflection (ie, ponding) is not included in the table. 2. Deck and mesh weight is not included in the weight of concrete figures. 3. Eurocode density of concrete is taken as: Normal weight (wet) 25 kN/m3 Normal weight (dry) 24 kN/m3 Lightweight (wet) 20 kN/m3 Lightweight (dry) 19 kN/m3 ComFlor® 51+ (S350) Section properties (per metre width)
