Terms and Definitions

There is specialized set of jargon to describe common terms used by manufacturers and other professionals associated with the usage of Steel Deck in the United States. The SDI has the following set of approved Terms and Definitions: Industry Standard Terms & Definitions of the Steel Deck Institute.

Advantages of Steel Deck

VERSATILITY
Steel decks complying with SDI Specifications are available from the member companies in various depths and rib spacings, with and without stiffening elements, with and without acoustical material, cellular and non-cellular, and in varying material thicknesses. This extensive choice makes steel deck applicable to a wide range of projects and structural designs.

STRUCTURAL STRENGTH WITH LESS WEIGHT
The properties of steel are used with maximum efficiency in the design and fabrication of steel decks, resulting in products with a high strength-to weight ratio. As a result, delivery, erection, and structural framing costs can be lower than with other systems.

ATTRACTIVE APPEARANCE
Although steel deck is primarily a structural component, it is visually attractive when left exposed in other applications. With the properly specified factory and field coatings, steel deck is easy to maintain, durable, and esthetically pleasing.

ALL WEATHER CONSTRUCTION
Steel deck can be erected in most weather conditions, eliminating the costly delays that can occur with other types of floor and roof systems.

REQUIRED FIRE RATINGS
U.L. fire resistance ratings on standard roof and floor assemblies have been obtained by the Steel Deck Institute. Individual SDI manufacturers have ratings on their own products. Most fire resistance requirements can be met with products manufactured by SDI members.

UNIFORM QUALITY
Through engineering and continuously refined production techniques, SDI manufacturers produce decks that conform to specified standards.

PROVEN DURABILITY
Steel deck in place and performing satisfactorily for more than a half century is indicative of the product’s durability.

ECONOMY AND VALUE
Value is determined by combining initial costs, life-cycle costs, and overall performance. Steel deck assemblies are the best value in floor and roof designs. They combine low cost with top performance.
