ComFlor® 80 | Composite Floor Decks Ltd

Concrete usage is further reduced by the profile shape, which eliminates an effective 44mm from the slab depth. Reduced slab depth and concrete volumes results in lower overall floor height, reduced dead loads on the structure and foundations, and savings on the total cost of the building structure. Fire properties of the ComFlor® 80 profile.
