Steel Deck

The most comprehensive deck line in the market

Canam manufacturers the United Steel Deck brand of Steel Deck Institute approved products.

Canam produces United Steel Deck products in South Plainfield, NJ, Peru, IL, and Jacksonville, FL. The original Canam deck product line is still produced in Jacksonville, FL and Sunnyside, WA. Steel deck was developed to provide a structurally efficient product for use in roof and floor systems. Its design and fabrication maximizes the properties of the steel in order to create a high strength-to-weight ratio,
which lowers the material, handling, and erection costs but maintains the durability that has been proven by over 70 years of satisfactory performance. Despite the fact that it is a structural component, its uniform quality can offer an attractive appearance, especially with the use of properly specified shop and field applied coatings. Steel deck is also a component of many U.L. approved fire rated assemblies. When steel deck is fastened at the supports and side laps it will provide a diaphragm that has strength and stiffness to transfer horizontal shear loads developed by wind and seismic forces to the vertical resistant system. The deck profile, fastener type, and fastener spacing will dictate the amount of resistance available to transfer these horizontal shear forces. The three primary types of steel deck are roof deck, composite deck, and non-composite (form) deck. The following features differentiate the three types of steel deck:

Roof Deck
Roof deck products are typically used as the structural component of many flat, pitched, or arched roof systems because of their benefits with regards to strength, weight, and economy. It is commonly attached to open web steel joists, structural steel, or light gage framing. Aside from the standard roof deck profiles, long-span, cellular, acoustic, and cellular acoustic products are also available to meet project needs. Shop curving of some roof deck products is also available with certain radius limitations.

Composite Deck
Composite deck is designed for use with structural concrete, and is manufactured with mechanical embossments in the webs to create mechanical and chemical bond between the deck and the concrete. The composite action allows the deck to serve as the tensile reinforcement for positive bending in the slab, which significantly reduces or eliminates the need for rebar in the slab and lowers material and labor costs. The strength and durability of the steel provides a solid platform for construction on top of open web joists, structural steel, light gage framing, or masonry walls. The deck acts as a form for the concrete and is typically designed so that shoring is not required. Cellular and cellular acoustic composite deck products are also available.

Non-Composite (Form) Deck
Non-composite deck, otherwise known as stay in place form deck, is used in conjunction with structural concrete or lightweight insulating fill for floor or roof applications. Because it does not have mechanical embossments in the webs, it cannot develop composite action, and other means of reinforcement must be used in the concrete. It strictly serves as a platform for concrete or fill over open web joists, structural steel, light gage framing, or masonry walls. Venting of form deck is also available as a means of venting the concrete or fill.

Canam has a wide variety of products for each type of steel deck to meet the needs of almost any project and make steel deck a smart and economical choice. Along with the standard SDI profiles we also offer the following specialty decks:

Long-Span (Deep) Deck
A variety of long-span decks are available for both roof and form applications. The profile depths of 4 ”, 6”, and 7 ” allow the deck to span longer distances between supports and achieve additional load capacity.

Cellular Deck
Cellular deck consists of a flat liner panel shop welded to a deck element to create a deck product that provides the strength of a corrugated deck while achieving a flat appearance from the underside. The cellular deck can be used for a roof, composite, or form deck application.

Acoustic Deck
Acoustic deck contains fiberglass insulation batts that are designed to absorb sound and prevent echoing within the space. For non-cellular deck there are perforations in the webs with fiberglass batts field installed on top of the deck in the low flutes. Cellular deck has perforations in the liner panel with the batts shop installed into the cells of the deck.

Bridge Form
Our bridge form product line consists of a variety of profiles that are typically used to form the slabs of bridges or thick slab applications. Specialty bridge accessories as well as crimped ends for some of our profiles are also available.

Custom Decks
Our 34’ tandem brake, variety of roll-forming tooling, and spot welding capabilities provide the capacity to fill special deck needs. We can also provide deck profiles of different metals such as stainless steel and aluminum and with a multitude of finishes.

Steel coils are ordered in accordance with ASTM A653 for galvanized steel and A1008 for uncoated steel. Steel gages can range from 10 to 28 depending on the product, and most deck types have a yield strength of at least 40 ksi. Several deck finishes are available, the most common being galvanized (G60 or G90) and/or shop primed (gray or white). See the Finishes page for additional information.
