One of the most important applications of HSS sections is in the construction industry. In general, the use of steel structures has advantages over other structures and building materials such as concrete, and HSS is without a doubt the best and most reliable of them. Having two or more axis of symmetry and a large radius of gyration, these sections are the most suitable option as columns or beams in structural systems because their main task is to tolerate gravity and lateral loads.
The steel materials in HSS profiles have the greatest distance from the axis passing through the center of the surface compared to other steel profiles. As a result, the hollow shape of HSS is more resistant and efficient. In addition, according to AISC standards, all the constituent parts of HSS sections have both butted edges, which delay their local buckling.
