Steel CHS Dimensions
CHS (Circular Hollow Section) is a round structural steel tube offering the best strength-to-weight ratio of any common structural section in pure compression, along with the highest torsional stiffness of any open or hollow section shape — making it a common choice for columns, bracing, and trusses, particularly where members are loaded from more than one direction or subject to torsion. Its round profile also reduces wind and fluid drag compared to a square or rectangular section, which matters for exposed structures and members in flowing water or air. The chart below gives dimensional and section property information for standard CHS sizes to BS EN 10219-2:2006.
The main drawback of CHS is connection complexity — bolting or welding beams directly onto a curved surface is more involved than onto a flat-faced SHS, RHS, or open section, which is why CHS is more often used for columns and bracing than as a primary beam bolted at both ends.

FREQUENTLY ASKED QUESTIONS
Why is CHS good for columns but less common as a beam?
CHS offers excellent compressive and torsional performance, ideal for columns and bracing, but its curved surface makes bolted connections at each end more complex and costly than with a flat-faced section like SHS, RHS, or an open UB/UC section — so it's used less often where straightforward beam-to-beam bolted connections are needed.
How is a CHS size described, e.g. "60.3 x 5 CHS"?
The first number is the outside diameter in mm, and the second is the wall thickness in mm.
