Hollow Section

High Strength-to-Weight Ratio
HSS is not only the most economical structural member, but the sections have a high radius of gyration about both axes which provides high torsional resistance and superior compression performance with significant weight savings. For increased axial capacity, HSS sections can be used as a jacket for a concrete column.

Closed Section
Unlike a channel W or I section which have one or more open sides, hollow structural sections are closed sections with all sides being closed off. This feature of HSS is advantageous for resisting torsional load. Used in environments such as food processing and clean facilities, where cleanliness is required, HSS is the best choice as it minimises surfaces that otherwise may collect dust and debris.

Aesthetic Appeal
Due to their smooth sides, rounded corners, and closed sections, HSS are often favoured by architects particularly when exposing the structure forms part of the appeal of a design. HSS have been used in iconic structures such as the London Eye and Emirates Stadium. They are also ideal for everyday applications such as vehicle trailers, fences, and handrails.

Cost Saving
Since rectangular and square HSS have about two-thirds the surface area of an open section of comparable capacity, this has a cost-saving benefit as there is less surface to prepare, fewer painting materials are required, cementitious fireproofing can be reduced, and minimal labour is needed.

Sustainable and Adaptable
Hollow structural sections are strong, durable, versatile, reusable and 100% recyclable. HSS not only create lightweight and visually attractive structures, but steel structures are inherently adaptable and can easily be extended at a later time without the worry of overloading the foundations of the existing structure.
