Types of Metal Roof Deck

B-Deck: B-Deck is one of the most economical types of metal deck available and is very easy to install. The ribs are 6 inches wide, and the legs can be interlocked to create side laps, ensuring a secure fit.

N-Deck: N-Deck is ideal for use in roofs or ceilings. Compared to B-Deck, N-Deck has greater depth, which is perfect for increasing the span without needing thicker materials.

A-Deck: A-Deck has a narrower design with rib spacing of 2-2.5 inches. While it is less durable, it is suitable for repair work where lower strength is acceptable.

F-Deck: F-Deck features ribs with slightly wider clearance than A-Deck. It is commonly used for repairing existing metal deck systems in older buildings but is not recommended as a replacement for B-Deck and N-Deck.

Cellular Roof Deck: A traditional corrugated roof deck with a flat piece of steel welded to the underside. This design increases spanning and loading capabilities while creating enclosed cellular raceways for utilities.

Form Deck: Our Metal Form Deck is ideal where a steel/concrete composite is not required.

Form Deck is perfect for floors, stairways, and more. Cordeck offers four popular Form Deck products, providing a wide variety of spanning and loading capabilities.

Composite Floor Deck: Metal deck used as a form to create a structural concrete slab. This type of deck includes embossments to help the concrete adhere, providing additional reinforcement and creating a strong, integrated floor system.

Cellular Composite Floor Deck: Is a traditional Composite Floor Deck with a flat sheet of steel welded to the underside. With the addition of the flat bottom plate, increased spanning and loading capabilities are achieved. As with traditional Composite Floor Deck, Cellular Composite Floor Deck creates a steel/concrete composite floor.
