Steel Frame


Steel frame usually refers to a building technique with a "skeleton frame" of vertical steel columns and horizontal I-beams, constructed in a rectangular grid to support the floors, roof and walls of a building which are all attached to the frame. The development of this technique made the construction of the skyscraper possible.

Anthony M DE WITT claims credit for introducing the American Steel Skeleton frame structure for buildings to the Cape, hence South Africa, in the late C19, used in JW Jagger's four-storey building in Cape Town.
