What is 1.5″ Roof Deck Type F?

1.5” Roof Deck Type F, also known as F Deck, Intermediate Rib Deck, or IR Deck, was developed with a wider rib opening than A Deck to increase its strength without using more steel. F Deck has since been replaced by B Deck. However, F deck is often used to retrofit existing F Deck in repair and restoration projects where matching the existing panel is critical. It is most commonly used in low-rise commercial roofing applications.
