3″ Composite Corrugated Metal Floor Decking

3” Composite Floor Deck

D-MAC Industries offers a 3″ composite floor deck for commercial public and private sector applications. Once the concrete cures within the vertical ribs, the composite floor system provides superior strength and durability, making it ideal for multi-level buildings like hospitals, garages, high rises, and more.

A 3″ composite floor deck requires more concrete but spans greater distances compared to shallower composite floor decks. At D-MAC Industries, we recommend pouring a minimum of 2” of concrete over the deck’s ribs for a total metal deck floor slab thickness of 5”.

3” Composite Floor Deck Applications

Our 3” composite floor deck is used where a composite floor deck is desired. Finished with a galvanized coated steel; our composite decks provide a permanent, strong application. Our 3″ composite floor deck has embossments that grip the concrete and are typically reinforced with rebar or wire mesh to create a strong bond with the concrete floor. Our 3″ composite deck ensures a permanent concrete form and eliminates the time and cost of wood forming, making it an efficient process. These are typically used in low-rise and high-rise commercial buildings, including bridges, slab infills, porches, and parking garages.

Options for 3” Composite Floor Deck

The 3″ composite deck is available in 16, 18, 20, or 22 gauges and is finished in galvanized steel for superior strength and durability. Galvanized steel is recommended for corrosive and high-moisture environments. Our 3″ composite metal deck is available in a 36 or 24-inch cover width and features a pitch of 12 inches.
