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.
