Rectangular Hollow Section · AS/NZS 1163 · Australia / New Zealand
200 x 100 x 9.0 RHS is a rectangular hollow section 200 × 100 mm with a 9.0 mm wall, weighing 37.7 kg/m. The dimensions below are the published AS/NZS 1163 values; the drawing is generated from them.
Rectangular Hollow Sections combine one strong axis with clean flat faces for connections, and resist torsion far better than open sections of similar mass.

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 100 x 9.0 RHS 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 | 227,559 mm³ |
| Elastic modulus, Zy | 152,885 mm³ |
| Plastic modulus, Sx | 293,450 mm³ |
| Plastic modulus, Sy | 180,456 mm³ |
| Radius of gyration, rx | 68.9 mm |
| Radius of gyration, ry | 39.9 mm |
Z is the elastic modulus and S the plastic modulus, following AS 4100. Under AISC 360 the letters are reversed.
