StructureCalcs60.3 x 2.9 CHS
Circular Hollow Section · AS/NZS 1163 · Australia / New Zealand
60.3 x 2.9 CHS is a circular hollow section 60.3 mm in outside diameter with a 2.9 mm wall, weighing 4.1 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 2.9 CHS the computed area agrees with the published value to 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 | 7,162 mm³ |
| Elastic modulus, Zy | 7,162 mm³ |
| Plastic modulus, Sx | 9,563 mm³ |
| Plastic modulus, Sy | 9,563 mm³ |
| Radius of gyration, rx | 20.3 mm |
| Radius of gyration, ry | 20.3 mm |
Z is the elastic modulus and S the plastic modulus, following AS 4100. Under AISC 360 the letters are reversed.
