What is composite deck made of?

Metal roof decks are used in commercial roofing as a foundation for flat steel deck, pitched, and arched roof systems because of their high strength to weight ratio of the steel.

Metal roof deck products act alone in transferring horizontal and vertical loads into the building frame, allowing for prescribed weight loads to be placed on the top of a building or structure. Metal roof decks can be left exposed for open ceiling designs or manufactured with added acoustical perforations.

Also known as steel roof decks, metal roof decks are known to provide a solid work surface for the installation of insulation, weatherproofing, and roofing materials. Metal roof decks are available in narrow rib, intermediate rib, wide rib, and deep rib and are used to support insulation or lightweight concrete and the waterproof membrane of a roof.
