(Type “B”) Wide Rib
Type “B” Roof Deck is a 1 1/2″ deep, wide rib, structural metal roof deck section that provides a support surface for various types of roofing materials, and 1” or thicker 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 B metal roofing deck is available in 24, 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). Material is typically in stock in 22, 20 & 18 gauge, G60, G90 or Gray Primer in 36” width.
