Hollow steel sections can withstand forces leading to high buckling, more effectively as compared to their open sections counterparts. The distribution of mass about the polar axis is more uniform in hollow sections as compared to open sections. This provides it a higher strength to weight ratio. Hollow sections have been proved more efficient as a truss and roof members. In present work, Hollow steel sections have been used in industrial shed building and compared with their open section counterpart. The scenarios of hollow sections are examined for change in height, change in bay length and change in span and the percentage cost savings and weight reduction are calculated. The study shows that the Hollow sections are more economical than the open section. However with increasing parameter, the economy shows a trend of shifting from hollow to open sections.
