Your experts for steel deck and metal deck
What is Steel Deck?
Steel deck, also called metal deck, is a corrugated sheet metal placed as a decking material over structural supports. Steel deck is popular for commercial construction due to its strength, light weight, low cost and easy installation. Nettles is a steel deck sales leader, and offers steel deck in a variety of gauges and profiles to customers across the Midwest and Texas.

Steel Deck Profiles We Stock
Type B roof deck
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.
Finishes: Primed Gray, G60 Galv. Gauges: 18, 20, 22. Sizes: 36″ × 20’2″, 36″ × 24’2″
Type F roof deck
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.
Finishes: Primed Gray, G60 Galv Gauges: 18, 20, 22. Sizes: 36″ × 20’2″, 36″ × 24’2″
Type A roof 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.
Finishes: Primed Gray and G60. Gauges: 22. Sizes: 36″ × 20’2″, 36″ × 24’2″
Type N roof deck
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.
Finishes: Primed Gray, G60 Galv. Gauges: 18, 20, 22. Sizes: 36″ × 24’2″
0.6C form deck
0.6C form deck (also called 9/16” form deck) is commonly used in floor construction to support concrete slabs.
Finishes: G60 Galv. Gauges: 22, 26. Sizes: 30″ × 20’3″
15/16″ form deck (1.0C)
1.0C form deck (also called 15/16” form deck) is ideal for heavy-duty applications, as it provides a strong base for forming slabs and serves as a permanent steel base for concrete floor slabs.
Finishes: G60 Galv. Gauges: 20, 22, 26. Sizes: 30″ × 20’3″
1.5″ form deck (1.5C)
1.5C form deck is made from high-strength steel and is used as a permanent base for concrete floor slabs.
Finishes: G60 Galv. Gauges: 18,20,22. Sizes: 30″ × 20’3″
1.5″ composite deck (1.5 VLI)
1.5” composite deck acts as a platform before and during concrete placement and is positive reinforcement for the concrete slabs, eliminating wood forms or the need for rebar.
Finishes: G60 Galv. Gauges: 18, 20. Sizes: 36″ × 20’0″, 36″ × 24’0″, 36″ × 27’0″
2.0″ composite deck (2.0 VLI)
2.0” composite deck creates a structurally sound and efficient flooring system, acting as a long-lasting and durable support structure for the concrete.
Finishes: G60 Galv. Gauges: 18, 20. Sizes: 36″ × 20’0″, 36″ × 24’0″, 36″ × 27’0″
3.0″ composite deck (3.0 VLI)
3.0” composite floor deck requires more concrete than 1.5” or 2.0”, but spans greater distances and is commonly used for pouring concrete slabs.
Finishes: G60 Galv. Gauges: 18, 20. Sizes: 36″ × 20’0″, 36″ × 24’0″, 36″ × 27’0″
