Your experts for steel deck and metal deck
What is metal deck?
Also called steel deck, pan deck, or Q deck, metal deck is corrugated sheet metal used in roof decks or composite floor decks. Metal deck is a popular choice for commercial construction, and offers benefits such as strength, light weight, low cost, and easy installation. At Nettles, we have decades of experience with all types of metal deck, and offer steel deck in a variety of gauges and profiles to customers across the Midwest and Texas.
Types of metal deck
Metal roof deck is installed over joists or beams on a roof deck, and attached by welding, screwing, or mechanically fastening the metal sheets to the steel. Roofing materials, insulation, waterproof membranes, and/or lightweight concrete can be installed over the metal deck to create a roof assembly.
Form deck is a permanent base for poured concrete slabs. It is typically used for lighter concrete pours, like stairs in commercial buildings, due to its smaller corrugation and lower gauge. Form decking is cheaper than pan decking, and is designed for smaller spans that are supported every few feet.
Also called pan decking or concrete decking, composite deck is used under suspended concrete slabs like basements or parking garages. Pan deck is more efficient and reliable than wood-framed suspended concrete, which is why it is now required in many U.S. cities.
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″
Advantages of metal deck
Why choose steel deck over other deck options? Metal deck is a popular choice for a variety of reasons, including:
- Strength: Steel deck is strong and offers a better strength-to-weight ratio than alternatives.
- Ease of installation: Metal deck is quick and easy to install.
- Weather resistance: Especially when protected by the G60 galvanized finish, steel deck will last a long time and is resistant to extreme weather conditions.
- Modularity: Metal deck is modular, meaning you can easily repair or replace only a section of it rather than the whole thing.
- High-quality material: All our metal deck is certified by the Steel Deck Institute, meaning it meets high standards of durability and performance.
- Price: Metal deck is a more cost-effective option than other roof or structural solutions.
