Choosing the Right Structural Deck for Floor and Roof Applications

Selecting the correct structural deck for a construction project is one of the most important decisions architects, engineers, and contractors make. The efficiency, stability, and life of the whole structure are dependent on a well-defined deck. Whether supporting roofing systems or forming part of a concrete floor slab, structural deck panels deliver the strength and reliability that modern buildings require.

Structural Deck Types Available at Keystar 

Type A Deck – Narrow Rib 

Type A structural decking features a 1-1/2” depth and 36” coverage width. This is a narrow profile of ribs that is mostly applied in repairing and patching the existing roof systems. Other forms of decking have proven to be more cost effective in new construction, but Type A is still useful in restoration work where there is a need to match older buildings. 

Type F Deck – Intermediate Rib 

Type F (intermediate rib) deck is also 1-1/2″ deep and 36″ wide and is a great support for roof patching and repair. Similar to Type A, it is comparable to older deck patterns that are common in existing buildings. Keystar stocks Type F deck to maintain and retrofit and provide contractors with hard-to-source profiles to make accurate repairs. 

Type B Deck – Wide Rib 

Type B structural deck is the most popular and widely used profile in new roof construction. It has a 36″ coverage and a depth of 1-1/2″, which provides the best strength to cost ratio. The Type B deck is lightweight, powerful and simple to install and is suitable in short to medium span conditions, which are usually between 3 and 12 feet. It is the most economical and versatile roof system in the modern world. 

Type N Deck – Deep Rib, Long Span 

Type N structural deck provides superior strength for long-span conditions. It is 3″ deep and allows more distance between structural supports without losing its load-bearing capacity. This profile is usually applied in massive commercial or industrial buildings where the span is maximized, and the steel gauge is minimized to lower the total material cost. Type N deck is the most popular when the objective is to have wide and open spaces with a reduced number of supporting members. 

Additional Decking Solutions from Keystar 

In addition to structural roof deck, Keystar also carries composite deck and form deck products. Composite deck is characterized by surface embossments which bond with concrete to form a single floor system whereas form deck is a permanent mold of concrete slabs without composite action. Keystar offers all the major types and profiles of decks, which means that it offers complete solutions to both new and existing structure contractors. 

Finishes and Manufacturing Standards 

All structural decking supplied by Keystar Industries is manufactured in the USA and meets or exceeds the standards set by the Steel Deck Institute (SDI). The decks come in galvanized or primer-painted finishes which are meant to offer strength, resistance to corrosion and easy installation. 

– Galvanized Finish: Provides better protection and life span against moisture and increases the life of the deck. 

– Primer-Painted Gray Finish: This is an economical coating that protects the deck during construction and can be used in the interior or in a project where other coatings will be applied later.
