HSS 203x102x6.4
AISC — Rectangular Hollow Section
Rectangular Hollow Sections (RHS) are tubular profiles with excellent torsional resistance and aesthetic appeal. Used for columns, trusses, and exposed structural elements.
The HSS 203x102x6.4 steel profile weighs 26.8 kg/m (18.01 lb/ft), has a depth of 203.2 mm (8.00 in), flange width 101.6 mm (4.00 in). Cross-sectional area: 3,457.4 mm². Moment of inertia Ix = 1,856.56 cm⁴, Iy = 620.9 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 5.9 mm ≈ 4 gauge (Manufacturers Standard Gage)
