3" composite floor deck is the deepest and most structurally sound concrete floor panel available. The deep profile allows a deeper and stronger pour of concrete therefore a higher slab depth is necessary, and very thick slabs can be achieved.
Composite slabs comprise reinforced concrete cast on top of profiled steel decking, which acts as formwork during construction and external reinforcement at the final stage. The decking may be either re-entrant or trapezoidal, as shown below.
Composite slabs consist of profiled steel decking with an in-situ reinforced concrete topping. The decking not only acts as permanent formwork to the concrete, but also provides sufficient shear bond with the concrete so that, when the concrete has gained strength, the two materials act together compositely.
Composite Decking over a Concrete Porch Gives a Backyard New Life By Tom O | February 9, 2018 | 0 Composite decking over a concrete porch repurposes a utilitarian area into a beautiful and attractive feature for your home.
