Square Hollow Section · AS/NZS 1163 · Australia / New Zealand
50 x 50 x 1.6 SHS is a square hollow section 50 × 50 mm with a 1.6 mm wall, weighing 2.4 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 50 x 50 x 1.6 SHS 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 | 4,682 mm³ |
| Elastic modulus, Zy | 4,682 mm³ |
| Plastic modulus, Sx | 5,461 mm³ |
| Plastic modulus, Sy | 5,461 mm³ |
| Radius of gyration, rx | 19.6 mm |
| Radius of gyration, ry | 19.6 mm |
Z is the elastic modulus and S the plastic modulus, following AS 4100. Under AISC 360 the letters are reversed.
