A Space Frame is a truss-like, a light-weight rigid structure constructed from interlocking struts in a geometric pattern. They are a common feature in modern building construction. The Main Advantage of Space Frames over PEB is they utilize a multidirectional span, and are often used to accomplish long spans with few supports. They are strong because of the inherent rigidity of the triangular frame; flexing loads (bending moments) are transmitted as tension and compression loads along the length of each strut.

The Space Frames are constructed of correlated members and nodes. The members and nodes are connected by high tensile bolts. The size of the members, nodes, and high tensile bolts is determined from the structural design. Space Frame building is a new alternative for the Pre Engineered Building Systems. SFBS are extremely rigid and stable when compared to any other existing structural system. This is widely used in all most all International Air Terminals. Suitable research and development were made to make this system applicable for Industrial / Institution applications. Its great aesthetic and sturdy appearance make it a good choice for architects and structural engineers to use SFBS in their projects.
