Circular Hollow Section FAQs

What is the advantage of using circular hollow sections over square or rectangular sections?

CHS steel distributes loads evenly, making it stronger against bending and torsion compared to square and rectangular hollow sections. The smooth, rounded profile reduces wind resistance, making it ideal for structural and exposed applications. Circular hollow sections offer aesthetically pleasing finishes for architectural steelwork.

What is the difference between hot-finished and cold-formed CHS steel?

Hot-finished CHS has higher strength, uniform mechanical properties, and better weldability, making it suitable for heavy-duty structural applications. Cold-formed CHS is cost-effective and lighter, making it ideal for fabrication and non-structural applications.

How do I select the right circular hollow section size for my project?

Based on your structural requirements, consider load-bearing capacity, wall thickness, and external diameter. Larger diameters with thicker walls are used for heavy-load structural applications. Contact IMS for custom-cut CHS steel sizes to match your engineering specifications.

Can circular hollow sections be welded and cut?

Yes, CHS steel can be welded, drilled, and cut using standard fabrication methods. IMS offers custom cutting and processing services for precise project requirements.

Are circular hollow sections suitable for outdoor and marine environments?

Yes, galvanised CHS steel provides corrosion resistance, making it ideal for outdoor and marine applications. Protective coatings or treatments can further extend longevity in harsh environments.
