Square Hollow Section · AS/NZS 1163 · Australia / New Zealand
65 x 65 x 4.0 SHS is a square hollow section 65 × 65 mm with a 4.0 mm wall, weighing 7.2 kg/m. The dimensions below are the published AS/NZS 1163 values; the drawing is generated from them.
Square Hollow Sections carry equal stiffness about both geometric axes, which makes them a natural column and truss-chord choice.

Derived section properties
Integrated from the section's own outline including its outside corner radii, whose arcs are integrated analytically rather than approximated by facets. For 65 x 65 x 4.0 SHS 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 | 16,978 mm³ |
| Elastic modulus, Zy | 16,978 mm³ |
| Plastic modulus, Sx | 20,599 mm³ |
| Plastic modulus, Sy | 20,599 mm³ |
| Radius of gyration, rx | 24.5 mm |
| Radius of gyration, ry | 24.5 mm |
Z is the elastic modulus and S the plastic modulus, following AS 4100. Under AISC 360 the letters are reversed.
