2" Composite Deck

NORMAL WEIGHT CONCRETE (145 pcf)

2" Composite is available in galvanized steel, and stainless steel. Composite Deck is meant to be used as a floor deck where concrete is to be poured on top of the deck. The web in the deck contains indentations, which allow for better bonding between concrete and deck, and therefore forms the Composite Deck. Temporary shoring may be required during construction. Consult the catalog for spans where shoring is required. 2" Composite comes roll formed to any custom length required and is available in 24" and 36" widths and has an interlocking side lap. Again, this product is readily available in stainless steel where corrosion resistance is critical. Stainless steel Decks provide the ability to prevent deterioration associated with conventional galvanized deck, thereby, eliminating debris-falling-from-the ceiling. Both types 304 and 316 are available.
