Structural Hollow Sections find applications in various aspects of architecture. They can be used as design elements to enhance aesthetics without compromising the structural integrity of a building. Architects have found use for Steel Hollow Sections in space frames, staircases, roofs, trusses, purlins, portal frames etc.

The Parliament Library building in Delhi brings out the use of hollow sections as members of the roofing system. Master Architects like Kisho Kurokawa, Lord Norman Foster, Frank O Gehry and Richard Rogers have made extensive use of steel hollow sections or closed structurals in their work.
