Type A (narrow rib) roof deck is 1-1/2″ deep and 36″ wide. Use Type A roof decking for repairs and patches since more economical types of roof deck (Type B) are now available. Additionally, Type A deck allows the maximum area for adhesive contact.
Type B (wide rib) is the most common structural roof deck because of its design. B deck provides the best combination of strength and economy in the 1-1/2” deep roof decking options because it is strong, lightweight, and easy to install. Use B roof decking mainly in short to medium span conditions ranging from 3 feet to 12 feet.
F (intermediate rib) roof deck is 1-1/2″ deep and 36″ wide. Ideal for use where insulation requirements are lower. Type F is most typically used for repairs and patches.
N roof deck provides a long span structural member. At 3” deep and 24″ wide, N roof decking meets specifications for structures where the supporting members need to be placed as far apart as possible. This deep rib deck gives contractors the opportunity to increase the span while decreasing the gauge of the metal.
