Expert Verdict — Reviewed by the SuperArbor Pro Desk
Type B wide rib is the most common choice where roofing is applied directly over deck because the wide top flutes uniformly support insulation and membrane. Match the 20 GA panel to the spans shown on your structural drawings and use the specified side-lap and deck-to-structure fastening. Reference the IAPMO/UL/FM datasheets when a listed assembly is required for your project.
Install deck panels with fall protection and proper panel handling equipment; panel edges are sharp and panels are heavy, so use gloves and crew lifts.
Specify Vulcraft Type B wide rib galvanized roof deck, 20 GA, 3 ft. x 21 ft. 6 in., for your next commercial roof.
