Square and circular HSS structural hollow sections are very efficient shapes for multiaxial loading. Because they have a uniform geometry along two or more cross section axes, so they have uniform resistance characteristics. This makes hollow structural sections a good choice for use as columns. HSS sections also benefit from very good resistance to twisting.

Hollow construction sections can also be used as beams. In many cases, wide flange or I-beam sections are more efficient structural forms for this application. However, HSS hollow sections have higher resistance to lateral torsional buckling. The flat square and rectangular surfaces of HSS hollow sections can facilitate construction and are preferred for architectural aesthetics in exposed structures. Elliptical HSS hollow sections are also more popular in similar exposed structures for aesthetic reasons.

The steel structure of the Beijing National Stadium, called the Bird’s Nest, is a good example that is made using HSS structural hollow sections and is considered a modern architectural masterpiece. The type of section applied in this structure has completely affected its beauty and volume. When constructing an exposed load-bearing structure, hollow structural sections (HSS) are more commonly used than open sections. Because the fewer connections are visible, the better. Also, the required connection between the hollow sections is also done by welding, which is considered better than the connection with bolts and nuts.

Construction hollow sections are among the most versatile and efficient steel products available for construction, construction and structural purposes. They are widely used in various industries and applications. The most common application of HSS is in welded steel frames and columns. They are also regularly used in steel support beams due to their great strength. Other common applications of hollow structural steel include:

Scaffolding
Fence and guard
Platforms and decks
bridges
The way of stairs
The gates
the trusses
Hydraulic platforms
Storage facilities and warehouses
Cranes and other heavy machinery
Furniture design and architecture
