Claim:
A composite deck system having a deck component and a concrete component, said deck component comprising: a first deck section having a first side wall connected to a first top surface, said first side wall including a first side edge having a first upturned flange, wherein said first upturned flange includes a first opening; and a second deck section adjacent to said first deck section having a second sidewall connected to a second top surface, said second side wall including a second side edge with a second upturned flange, wherein said second upturned flange is adjacent to said first upturned flange, and wherein said second upturned flange includes a second opening, said first and said second openings being left open to allow a concrete layer, when said concrete layer is applied to said deck component, to flow between said first deck section and said second deck section through said first and second openings so that, upon curing, said concrete layer acts in concert with said first and said second side edges to lock said first and said second deck sections together vertically and horizontally.
