Cost effective, By as a result of its shape hollow sections have high radius of gyration andother properties resulting in savings in material, Transportation andfabrication cost. Less surface area compared to equivalent conventional sections results insavings in paint and labour costcorrosion resistant, Less exposed surface area combined with superior Superior natural componentsresults in less corrosion. Smooth uniform profiles of sections minimizes dust and moistureaccumulationconcentric strength, By virtue of its shape hollow sections have high radius of gyration resultingin higher concentric strength. Compared to conventional sections. Due to closeness of the section there is going to be higher torsional rigidity better lateral stability and lower wind drag. Enables weight reduction of upto 30%.
