If you’re planning a roofing project that requires long spans and structural integrity, N-Deck—also known as deep rib roof decking—may be the ideal solution. At CSM Metal Deck, we specialize in supplying high-quality N-Deck products that are both versatile and cost-effective. Whether you’re working on an industrial warehouse, school, canopy, or awning, here’s everything you need to know about N-Deck and why it could be the right choice for your next build.
What Is N-Deck?
N-Deck is a type of metal roof decking known for its deep, 3-inch rib profile. This ribbing makes it significantly stronger than other deck types like B-Deck, allowing it to span longer distances between roofing supports. Its ability to support larger spans with fewer steel supports makes it a popular option in large-scale commercial and industrial construction.
At CSM Metal Deck, we manufacture and stock N-Deck in 22, 20, 18, and 16 gauge, with a standard width of 32 inches. Its lightweight construction makes it easy to install, and its structural strength supports spans of 1 to over 20 feet, depending on gauge and back-span conditions (single, double, or triple).
Common Applications
N-Deck is typically used for:
- Roofing systems in warehouses, schools, and large facilities
- Canopy construction
- Awning structures
- Projects requiring longer spans or fewer structural supports
Its strength and ease of use make it an efficient alternative to open web steel joists and more cost-effective than B-Deck in many cases.
Finishes Available
Choosing the right finish is essential for performance and durability.
CSM Metal Deck offers a variety of N-Deck finishes tailored to your project environment:
- Prime Painted Finish: Gray prime paint over bare steel is the most affordable finish. It provides temporary protection during construction and long-term protection in dry interior environments.
- Galvanized Finish: Available in G60 and G90, this finish offers corrosion resistance in aggressive environments, making it ideal for projects exposed to moisture during or after construction.
- Galvanized/Painted Finish: Combines the protection of galvanized steel with a white or gray prime-painted bottom, recommended for environments with humidity or potential corrosion.
Acoustical N-Deck
For projects where sound control is important, we also offer acoustical N-Deck. This variation features perforations and embossments that absorb and dissipate sound, making it a smart choice for auditoriums, schools, and any environment requiring noise reduction.
