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.
