Square Hollow Section · AS/NZS 1163 · Australia / New Zealand
200 x 200 x 12.5 SHS is a square hollow section 200 × 200 mm with a 12.5 mm wall, weighing 69.4 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 200 x 200 x 12.5 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 | 499,919 mm³ |
| Elastic modulus, Zy | 499,919 mm³ |
| Plastic modulus, Sx | 607,321 mm³ |
| Plastic modulus, Sy | 607,321 mm³ |
| Radius of gyration, rx | 75.2 mm |
| Radius of gyration, ry | 75.2 mm |
Z is the elastic modulus and S the plastic modulus, following AS 4100. Under AISC 360 the letters are reversed.
