Type F Deck (Intermediate Rib)

Roofing & Siding

Type F Intermediate Rib is an older deck profile still widely used, particularly where roofs must nest with an existing F deck roof. All attributes that apply to B deck also apply to F deck. Load carrying capabilities for Type F deck are less than Type B deck.
