High Strength-to-Weight Ratio
Due to its structural efficiency, HSS is frequently the most cost-effective structural element. High gyrating radii about both axes of HSS provide both considerable weight reduction and improved compression performance.
Because of its smooth sides, rounded angles, and closed sections, HSS are frequently used in architecture and are the best option when revealing the structure is needed.
Less Surface Area for Coatings
RHS has a surface area that is around two thirds less than an open section with a similar capacity. As a result, there will be less surface preparation, less paint and labour, and less cementitious fireproofing.
It is preferable to resist torsional loads with closed sections. Additionally, HSS are a sensible choice since they have less surfaces that might gather dust and dirt in areas where cleanliness is required, such as in food processing and other clean operations.
