ComFlor® 80

The next generation of profiled steel composite decks

ComFlor80

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

The large corner curvature detail provides a very efficent 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 achiveable means less structural steel and thus cost saving in the overall construction cost, providing more scope for architects and engineers in their design process. Central stud placement provides superb composite action between the beam and concrete due o the stud being positioned exactly in the center of the trough. This ensures the correct concrete cover to the stud 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.
