Use these resources to quickly match or identify your existing roof deck.
Follow these three simple steps to identify your steel deck or metal deck:
1. Measure these dimensions on your deck:
2. Find your deck’s dimensions in the table below and match it to the steel roof deck type:
3. Once you’ve determined whether your steel roof deck is type B, A, F, or N, contact us to place your order or get a quote!
Steel deck profiles we stock
Type B roof deck, also called “wide-rib roof deck,” is the most common roof deck used today. It has a 1.5” profile and wide ribs, giving it the highest strength-to-weight ratio of any 1.5” profile. This allows B deck to carry higher loads and make longer spans than Types A or F.
Type F is a 1.5” profile with an intermediate rib width. Much like A deck, F deck is most often required to repair and replace existing F deck on older buildings. F deck is stronger than A deck, but not as strong as B deck.
Type A steel roof deck is a 1.5” profile with a narrow rib that is found on older buildings. We stock this deck type for repairing and replacing existing A deck on older buildings.
The Type N roof deck, also called “deep-rib roof deck,” has a 3” deep profile which gives it the highest load carrying capacity of the most common roof deck profiles. The added strength of N deck makes it ideal for applications where supporting members need to be spaced further apart, like gymnasiums and other high volume spaces.
