Go with CUNMAC – Exploring insights of metal decking, from roof deck to floor deck with common types, applications and some key characteristics.
1. What is metal decking? Applications of metal decking
Decking is a term usually used in constructions and structures. Metal decking is a specific type of decking. It refers to a metal sheet with corrugations, which are grooves or ridges.
Metal decking is supported by other materials such as beams and joists to provide roof support insulation or bond with concrete to form composite metal floor/wall cladding.
Generally, metal deck or steel deck is used to strengthen and enhance building durability, suitable for most building types, for one-story or multi-story structures.

2. Types of metal decking
Different metal decks have been designed to suit various purposes and styles over the years. Based on the purpose, metal decking can be classified into roof deck and floor deck.
2.1 Roof deck
Metal roof decking is a popular choice in commercial and industrial buildings. It provides a sturdy base for roofing systems to be built on.
Thanks to its strength, light weight and affordability, metal roof deck is suitable for various structure types such as flat roof, pitched roof…
There are four common types of metal roof deck: B-Deck, N-Deck, F-Deck and 1’’ Roof Deck
Metal roof deck
B-Deck
Among these types of roof decking, B-Deck is one of the most commonly used. B-Deck is named based on its profile, with the letter “B” denoting its shape.
B-Deck standard profile comes with 1.5” deep and 36’’ cover width. In practice, B Decking is the ideal solution for short to medium span applications that span 10 feet maximum.

N-Deck
N Deck is a long span, 3’’ deep and 24’’ cover width metal deck. Due to its deeper grooves and better strength compared to B Deck, N Deck is a go-to choice for roofs with a span exceeding 10 feet.

F-Deck
F Deck is a basic type of metal roof decking with a profile 1.5” deep and 36” wide. It is only recommended for repairing or replacing old roofs.
1’’ Roof Deck
With its 1-inch deep ribs, 1″ Roof Deck is a reliable roof deck. While it shares common uses with N Deck, it’s better suited for short to medium distances instead of longer spans.

2.2 Floor Deck
Floor deck is also known as a composite deck, because it is used together with concrete to establish a durable foundation for building structures.
The combination of floor deck and concrete provides long-lasting form and extra strength for the construction.
Typically, metal floor decks come in three types: 1.5″ Composite Deck, 2″ Composite Deck, and 3″ Composite Deck.
1.5 Inch Composite Deck
1.5’’ composite deck is the lowest profile type. It is best used for short spans with durable and easy-to-install features.

2 Inch Composite Deck
A 2-inch composite deck is capable of supporting thicker concrete slabs than a 1.5-inch deck. It is frequently used for longer structural spans.
3 Inch Composite Deck
The 3-inch composite metal deck is the thickest floor deck and can hold heavier concrete than 1.5 or 2-inch decks. It’s typically chosen for long-span outdoor flooring projects.

3. Key difference between metal roof deck and floor deck
While profiles and dimensions may appear similar, the primary difference between roof decking and floor decking lies in the embossment patterns:
- Floor deck features a distinct embossment pattern that binds with poured concrete, creating a composite foundation.
- Roof deck, smooth without embossment, supports roofing system elements like insulation and built-up roofing.
