Panels and Profiles

ComFlor® 80

ComFlor® 80

ComFlor® 80 – is the next generation of profiled steel composite decks; it is the only 80mm profile available in Colorcoat® pre-finished steel to provide a durable and attractive appearance.

The large corner curvature detail provides a very efficient profile. In conjunction with the higher grade of steel, it ensures typical unpropped spans of 4.4m simply supported and in the continuous condition, spans of 5m can be achieved.

The large spans achievable means less structural steel and thus cost saving in the overall construction cost, providing more scope for architects and engineers in their design process.

The innovative profile design provides real benefits.

Central stud placement provides superb composite action between the beam and concrete due to the stud being positioned exactly in the centre of the trough. This ensures the correct concrete cover to the stud and hence, the full design capacity of the stud is developed. The central location of the stud also reduces on-site checking to ensure that the stud has been positioned correctly.

Ideal for car parks ComFlor® 80 is available with a Colorcoat® pre-finished steel underside for use in car parks, giving a durable and attractive appearance and minimising future maintenance.

Excellent concrete usage means that ComFlor® 80 is very economical compared to other similar decks.

Improved manual handling The cover width of ComFlor® 80 is 600mm, to reduce sheet weight and improve handling.

FibreFlor mesh free system ComFlor® 80 is fully tested with the FibreFlor system to provide all the no mesh benefits. See following pages for the load tables and further design information.

Volume & weight table notes
1. Deck and beam deflection (i.e. ponding is not allowed for in the table).
2. Deck and mesh weight is not included in the weight of concrete figures.
3. Density of concrete is taken as:

    •  Normal weight (wet) 2400 kg/m3
    •  Normal weight (dry) 2350 kg/m3
    •  Lightweight (wet) 1900 kg/m3
    •  Lightweight (dry) 1800 kg/m3
