Whether your design calls for acoustic insulation, mechanical fasteners, or a specific finish, Cordeck’s B Deck easily integrates into your system while maintaining structural performance and aesthetic consistency. Its wide rib design provides superior diaphragm shear values and load-carrying efficiency, making it the dependable foundation for roofing assemblies of all kinds.

Custom Options to Match Every Project

Cordeck maintains a wide range of steel coils and can manufacture to length based on project specifications, eliminating waste and simplifying installation. Available in multiple gauges—22, 20, 18, and 16—the 1.5″ B Deck can be tailored to your project’s load and span requirements.

You can also choose from a variety of finishes to suit performance and aesthetic needs:

  • Galvanized – G60 or G90
  • Prime Painted – Gray or White
  • Finished Painted – High-reflective White with other popular options available
  • Galvanized Painted
  • Stainless Steel – 304 or 316

These options allow design and construction teams to select the right balance of corrosion protection, reflectivity, and visual appeal for each application—whether an exposed-ceiling aesthetic or a concealed structural system.

While N and A decks serve specific roles in the industry, the 1.5″ B Deck stands out as the most commonly specified due to its balance of strength, span capacity, and economy. Compared to A Deck (typically 1.5″ deep), B Deck offers greater span capability and diaphragm strength, while remaining lighter and more cost-effective than deeper profiles like 3.0″ N Deck. This makes it the go-to option for most commercial and industrial roofing systems, combining practical performance with efficient installation.

Every Cordeck deck profile is manufactured under strict quality standards and supported by decades of experience serving the nation’s builders. With strategically located manufacturing facilities across the United States, Cordeck ensures rapid delivery and reliable service wherever your next project takes you.

Additional Roof Deck Profiles, Cordeck Offers — And Their Applications

While the 1.5″ B Wide Rib Roof Deck is the “workhorse” choice for many projects, Cordeck offers a broader portfolio of roof deck profiles optimized for different span, aesthetic, acoustic, or structural requirements.

Ideal for shorter spans and lighter roof loads, the A Deck is the go-to option when interior aesthetics matter most. With its shallow, narrow rib profile, it’s often used in reroofing or retrofit applications, or anywhere ceiling exposure and visual appeal are design priorities.

Sitting between the A and B profiles, the F Deck delivers moderate span and load capabilities, offering a balanced solution for mid-range applications. It’s commonly used when the B Deck’s wide rib is not required but added stiffness is beneficial.

For projects demanding long spans and high load capacity—such as warehouses, manufacturing plants, and distribution centers—the N Deck provides maximum structural performance. Its deep 3.0″ rib supports heavier mechanical equipment, green roofs, and increased diaphragm shear strength, all while reducing the need for intermediate supports.
