Metal decking is used in a wide variety of commercial and industrial applications. It includes steel roof and floor decking, aluminum floor decking, and acoustical metal decking. Metal decking typically has a ribbed or corrugated profile that is achieved through a process called roll forming. Large sheets of metal are pulled off of rolls and led through rolling dies that create the ribbed profile. Metal decking is used for flooring and roofing and also for the creation of forms for concrete. Metal decking is installed by using screws or pneumatically driven pins and can also be welded.

Structural aluminum framing in commercial applications is most commonly used in curtain wall assemblies and as framing members when the building's dead load is an issue. Structural aluminum framing is also used in greenhouses and glass enclosures. In residential construction, structural aluminum is used for custom jobs with large glazed areas, as well as for framing outdoor awnings.
Structural steel framing, which includes structural stainless steel framing, describes the creation of a steel skeleton made up of vertical columns and horizontal beams. This skeleton provides the support for the roof, floors and walls of the structure. There are three main types of structural steel framing systems. They are the clear-span rigid frame structure, the modular structural frame and single slope frame style. Choosing which type of steel frame to use for a given project requires the consideration of a number of factors, including building width, height, location, roofing type, and building use.
Structural metal framing is used in nearly every type of commercial and residential construction. Rigid frame construction forms the skeleton of many buildings. It allows for long and heavy spanning beams, girders, rafters, and columns. Framing can be comprised of various metals and can be made into custom shapes and multiple configurations, providing endless options for project planners.
Steel joist framing provides an efficient framing system for supporting floors and ceilings in a wide variety of building types. Steel joists are economical and lightweight with an exceptionally high strength-to-weight ratio. Since steel joists are lighter than wooden trusses, the size of the supporting structural elements as well as the size of the building's foundation can be reduced for cost efficiency.
