Common Uses

Circular hollow section is widely used for structural columns and posts, support frames, bracing members, handrails and balustrades, gate and railing fabrication, agricultural structures and general structural tube work. Its round profile gives uniform strength in all directions.

Circular vs Box and Rectangular Section

Circular hollow section (CHS) gives even strength in all directions, ideal for columns, posts and handrails. Square box section (SHS) and rectangular hollow section (RHS) have flat faces that are easier to join and weld for frames and load-bearing spans. Choose CHS where a round profile or uniform strength is required.

Finish and Protection

Supplied in standard mill finish. The surface may show normal mill scale, handling marks or light surface oxidation, typical for untreated steel. For outdoor or moisture-exposed use, clean, prime and protect with a suitable paint or coating system.

Cutting and Fabrication

S235 circular hollow section can be cut, drilled, welded and fabricated using suitable metalworking tools. Cut ends and drilled holes should be protected if used outside or in damp conditions.

Delivery Information

Lead times are currently 3-5 working days. Delivery is kerbside only and our vehicles do not carry HIAB or lifting equipment - steel must be safely offloaded by the customer on arrival. Sections are supplied in full 7.5m lengths, so suitable delivery access is required.
