Metal Roof Deck

Metal roof decking is a corrugated steel panel installed directly over structural steel framing to serve as the structural substrate for a commercial or industrial roof system. Cordeck manufactures four metal roof deck profiles. Each has a distinct rib width and depth that determines its spanning capability, load capacity, and ideal application.

1.5” A Deck Narrow Rib Roof Deck

A Deck is a 1.5” narrow rib steel roof deck available in a standard 36” coverwidth, gauges 22, 20, and 18, and multiple finishes including galvanized, painted, and stainless steel. It is a nestable profile, meaning sheets stack tightly for efficient shipping and handling.

A Deck is best suited for shorter roof spans and is commonly specified for retail, small office buildings, light industrial warehouses, mezzanines, and architectural applications where the corrugated underside is intentionally exposed.

1.5” B Deck Wide Rib Roof Deck

B Deck is the most widely specified steel roof deck profile in commercial construction. Its wide rib provides greater spanning capability than A Deck, making it the standard choice across a broad range of commercial and industrial applications. Available in a standard 36” coverwidth with additional coverwidths of 24” and 30”, in gauges 22, 20, 18, and 16.

Roof Deck Questions, Answered

A Deck is the right choice for shorter roof spans or when the exposed corrugated underside is part of the architectural design intent. Its nestable profile also makes it more efficient to ship and handle on constrained job sites.

B Deck’s wider rib provides greater spanning capability, making it the more versatile and widely specified option for standard commercial and industrial roof applications.

F Deck is specified when repairing or replacing existing F Deck in an older building where the original profile needs to be matched. It is not recommended for new construction in place of B Deck or N Deck.

N Deck is specified when a project requires longer spans, heavier load capacities, or acoustical performance such as in gymnasiums, auditoriums, or natatoriums.

Spanning capability depends on the deck profile, gauge, and load requirements specified by the structural engineer. Generally, 1.5” profiles span up to approximately 8  to 10 feet, while the 3.0” N Deck can accommodate significantly longer spans. Always refer to the applicable load table for the specific profile and gauge being specified.

Nestable profiles stack tightly for efficient shipping and storage. Interlocking profiles have side laps that mechanically connect adjacent sheets during installation, providing improved structural performance across the side lap joint.

Yes. Cordeck offers a full range of accessories including screws, ridge plates, valley plates, cant strips, finish strips, sump pans, end and side closures, pour stops, deck plate, and rubber cell closures.

Metal Form Deck

Metal form deck is a corrugated steel panel used as a permanent form for poured concrete in floor and stair construction where structural composite action between the steel and concrete is not required. It supports the concrete during placement and curing, and remains in place permanently as part of the finished structure. Form deck is also widely used in non-structural interior design applications. Cordeck offers three metal form deck profiles.

0.6” Form Deck

The shallowest profile in Cordeck’s form deck lineup, best suited for shorter spans and lighter loads. Available in a standard 36” coverwidth in gauges 28, 26, 24, and 22.

1.0” Form Deck

Offers mid-range spanning capability for applications requiring slightly greater span or load than the 0.6” profile can accommodate. Available in a standard 36” coverwidth in gauges 26, 24, 22, and 20.

1.5” Form Deck

The deepest and most versatile profile in the form deck lineup, offering the greatest spanning capability and the widest range of gauge and finish options including stainless steel. Available in a standard 36” coverwidth with additional coverwidths of 24” and 30”, in gauges 24, 22, 20, 18, and 16.

Form Deck Questions, Answered

Metal roof decking is installed on roofs as a structural substrate. Form deck is used for floors and stairways where it acts as a permanent form for poured concrete. The two products serve different structural purposes and are not interchangeable.

Form deck is used when the engineer of record has not specified composite action in the floor system. It is also specified for stairway construction and non-structural interior applications such as decorative wall panels and exposed ceiling systems.

Rib depth is the primary difference. The 0.6” handles shorter spans and lighter loads. The 1.0” provides mid-range spanning. The 1.5” handles the longest spans in the lineup and offers the broadest range of gauges and finishes, including stainless steel.

22 gauge is the most common gauge specified for standard applications. Floor construction in commercial and industrial buildings where composite action is not required is the most common use case.

Yes. Form deck’s corrugated profile is well suited for non-structural interior applications including decorative wall panels and exposed ceiling systems. The 1.5” Form Deck is particularly popular for this use given its wider range of finish options.

Composite Metal Floor Deck

Composite floor deck is a corrugated steel panel with embossments that allow poured concrete to mechanically bond to the steel, creating a composite structural floor system. Unlike form deck, composite floor deck develops structural composite action between the steel and the concrete, resulting in a stronger, more efficient floor system that reduces the amount of structural steel required in the overall building design. Cordeck offers three composite metal floor deck profiles.

1.5” Composite Floor Deck

The standard spanning option, typically specified for multi-story office buildings and standard commercial floor applications.

Composite Floor Deck Questions, Answered

Composite floor deck is a corrugated steel panel with embossments that allow poured concrete to mechanically bond to the steel, serving as both the permanent form during concrete placement and a structural component of the finished floor. The composite action between steel and concrete reduces the amount of structural steel required in the building design.

Composite floor deck is specified when the engineer of record has called for composite structural action in the floor system. Form deck does not have the embossments required for composite action and cannot be substituted when the structural design requires it.

Composite floor deck creates a strong, integrated structural floor system, eliminates the cost and labor of removing temporary formwork, and is available in multiple profiles to suit a wide range of spanning and loading requirements.

Cordeck Laser 2

Laser Cutting Services

Cordeck’s laser cutting services use a Bystronic fiber laser system at the Kenosha, Wisconsin headquarters and Denton, Texas facility. Fiber lasers cut faster and with better edge quality on metals than traditional CO2 lasers, delivering tighter tolerances and cleaner cuts across a wide range of materials including steel, stainless steel, brass, copper, and aluminum.

Clean cuts eliminate the need for secondary finishing, reduce rework, maximize material yield, and keep projects moving. Tight tolerances mean the actual cut closely matches the specified design dimension, which is critical for components that must fit together precisely during installation.
