StructureCalcs60.3 x 2.3 CHS
Circular Hollow Section · AS/NZS 1163 · Australia / New Zealand
60.3 x 2.3 CHS is a circular hollow section 60.3 mm in outside diameter with a 2.3 mm wall, weighing 3.3 kg/m. The dimensions below are the published AS/NZS 1163 values; the drawing is generated from them.
Circular Hollow Sections are cold-formed tubes to AS/NZS 1163 — efficient in compression and torsion, with identical stiffness about every axis.

Derived section properties
Integrated analytically from the exact circular tube. For 60.3 x 2.3 CHS the computed area agrees with the published value to better than 0.01% and Ix to better than 0.01%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 5,854 mm³ |
| Elastic modulus, Zy | 5,854 mm³ |
| Plastic modulus, Sx | 7,741 mm³ |
| Plastic modulus, Sy | 7,741 mm³ |
| Radius of gyration, rx | 20.5 mm |
