Steel composite floor decking / Floor & Deck Structure Systems
Composite floor decking applications, such as multi-story car parks, schools, colleges, hospitals and multi-storey offices.
A range of seven steel composite floor profiles, each designed specifically for a particular application area. The range offers many benefits including speed of installation, long spanning capabilities, lightweight buildings, excellent fire resistance, all responsibly sourced from a UK factory and certified to BES 6001.
ComFlor® specifically designed for rapid installation of flooring and to facilitate lower mass buildings with long clear span composite concrete floors. Large areas can be easily craned into position and in excess of 400 m² laid by one two-man team per day. With minimal mesh or fibre reinforcement and pumped concrete, the completed floor can quickly follow.
With ComFlor® 46, 51, 60, 80 and 100 covering unpropped construction up to 4.5 m, and propped spans in excess of 7 m, each profile offers particular application benefits.
The decks are suitable for conventional composite construction where the deck is on the top flange of the steel support beam.
ComFlor® 210 and 225 are both designed to be used with the Slimdek® system, or another integrated beam system with asymmetric beams that allow the floor deck to land on the bottom flange. With typical unpropped spans extending to 6 m and propped spans to 9 m the deep decks provide clear open space between beams.
The deck is contained within the beam depth, which provides a very shallow floor zone. The shape of the deck profiles allow for service integration and the whole system provides inherent fire resistance.
ComFlor® 9.0.34 Software analyses each of the ComFlor® composite floor decks in construction stage, service stage and for fire resistance, under a wide range of loading configurations.
Design principles are in accordance with the appropriate parts of BS 5950 : Part 4 (1994), Part 6 (1995), Part 8 (1991) For design to the Eurocodes, the design principles are in accordance with BS EN 1993-1-3, 1994-1-1 and EN 1994-1-2:Eurocode 4. The design checks performed by the program cover the construction stage, the normal design stage and fire.
The range includes:
- ComFlor® 46:
Classic composite flooring, 46 mm deep profile, easily transported, simple and efficient.
- ComFlor® 51+:
A contemporary new design of the original British 51 mm deep re-entrant profile.
- ComFlor® 60:
Combined trapezoidal and re-entrant, 60 mm deep profile.
- ComFlor® 80:
Combined trapezoidal and re-entrant, 80 mm deep composite profile with long span capability.
- ComFlor® 100:
Strong long span, 100 mm deep composite profile for non-composite beams.
- ComFlor® 210:
The original deep ultra-long span, 210 mm deep composite profile introduced for the first Slimflor® systems.
- ComFlor® 225:
High performance, 225 mm deep deck specifically designed to enhance for Slimdek® and all other integrated steel beam systems.
- ComFlor® Formwork:
32 to 210 mm deep non-composite profiles are available which are used as permanent formwork.
Features and benefits:
Fire performance and load/ span information:
Consult technical literature for details.
Minimum trapezoidal deck concrete cover required to achieve the following fire resistance:
Supporting beam width:
The width of the supporting beam used as default in our design software and load-span tables is taken at 152 mm, except for deep decks which are assumed to bear on an extended bottom flange 400 mm wide.
Standard unpainted finish for steel composite floor decks
- Colorcoat FD® 25:
Suitable for use where the exposed soffit is used as a feature of the building's interior. Topcoat is available in white as standard.
- Colorcoat FD® 170:
Suitable for use where the exposed soffit is used as a feature of the building's interior and where greater environmental protection is required.
Through deck welded shear studs cannot be used, however alternative fixing options, such as pre-stud welding the beam are available.
