Keystar Industries Type F Decking products provide a convenient choice for patching or repair projects on flat roofs. F Decking at 1.5” deep, also known as intermediate rib decking, gives a wide support surface. This feature is ideal for applications where insulation requirements are lower.
Features of Type F Decking
The design and fabrication of F roof decking maximizes steel’s properties in order to create a high strength-to-weight ratio. Lower material, handling, and erection costs result from using F roof decking.
Keystar Type F Deck products meet the required steel deck certifications in accordance with the specifications of the Steel Deck Institute. The material thickness of the intermediate rib deck stocked by Keystar measures 20 gauge. This structural metal decking measures 36” wide and can transfer horizontal and vertical loads into the building frame.
This roof deck comes with a primed or galvanized finish. The most economical finish for type F decking is prime painted gray over bare steel. Typically, this finish provides adequate temporary protection to the base metal of the metal decking during construction.
Comparison of Type F Decking Types
At present, F deck is rarely used for new construction projects but is often needed for repair and re-roof projects. Compared to Type B deck, Type F Deck has a lower strength-to-weight ratio. Since Type F Deck cannot carry as much load at longer spans as B deck, the steel supports below the metal deck must be spaced closer together. Smaller support spacing results in more supports and higher construction costs.
When type A roof deck and type F roof deck were developed, the engineering community focused on the strength of the metal deck. However, it was only a secondary factor of concern. The primary objective was to maximize the width of the top flange. This factor provided the maximum amount of support for the roofing insulation that would be installed on top. Over time, roofing materials improved and steel deck manufacturers were able to reduce the width of the top flange. This reduction increased the efficiency from Type A deck to Type F Deck, and finally from Type F deck to Type B deck.
