Space Frames - Structures.

Steel skeletal space frames are three-dimensional structures capable of very large column-free spans.These structures, constructed from either individual elements or prefabricated modules, process a high strength-to-weight ratio and stiffness. Steel space frames may be used efficiently to form roofs,walls and floors for projects such as shopping arcades, but their real supremacy is in providing roof cover for sports stadia, exhibition halls, aircraft hangars and similar major structures.
