Type “A” Roof Deck is a 1 1/2″ deep, narrow rib, structural metal roof deck section that provides a wide support surface for various types of roofing materials, and thinner rigid insulation. Roof deck products act alone in transferring horizontal and vertical loads into the building frame, and do not work compositely with other building materials. Type A metal roofing deck is available in 22, 20, 18, and 16 gauge with either a galvanized (G60 or G90) finish or prime painted (gray or white) to inhibit rust while in transit (primer is not a finish coat). Material is typically in stock in 20 gauge, G90 or Gray Primer in 36” cover width.
(Type “N”) Deep Rib
Type “N” Roof Deck is a 3″ tall, deep rib metal roof deck, that is designed to provide an economical roofing support surface when longer spans are required between roofing supports. Roof deck products act alone in transferring horizontal and vertical loads into the building frame, and do not work compositely with other building materials. Type N Metal Roof Deck is available in 22, 20, 18, & 16 gauge with either a galvanized (G60 or G90) finish or prime painted (gray or white) to inhibit rust while in transit (primer is not a finish coat).
