Rectangular HSS · AISC Shapes Database v15.0 · United States
HSS10X6X3/8 is a rectangular hollow structural section 254 × 152 mm with a 9.5 mm wall, weighing 56.1 kg/m. The dimensions below are the published AISC Shapes Database v15.0 values; the drawing is generated from them.
Rectangular HSS are cold-formed tubes that AISC tabulates on the design wall thickness (0.93 × nominal) — the note beside the derived table explains what that convention does to the numbers.

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 HSS10X6X3/8 the computed area agrees with the published value to 0.43% and Ix to 0.29%. Where a value is also published, the published one above is the one to quote.
AISC tabulates hollow-section properties on the design wall (tdes = 0.93 tnom, per AISC 360), while the published mass reflects the nominal wall — which is why mass and area here differ by about 7% by convention, on every AISC hollow section.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 447,715 mm³ |
| Elastic modulus, Sy | 337,063 mm³ |
| Plastic modulus, Zx | 552,640 mm³ |
| Plastic modulus, Zy | 388,075 mm³ |
| Radius of gyration, rx | 92.3 mm |
| Radius of gyration, ry | 62.0 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
