HSS 50x25x3.2
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 50x25x3.2 steel profile weighs 3.3 kg/m (2.22 lb/ft), has a depth of 50.8 mm (2.00 in), flange width 25.4 mm (1.00 in). Cross-sectional area: 421.2 mm². Moment of inertia Ix = 13.21 cm⁴, Iy = 4.21 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3 mm ≈ 11 gauge (Manufacturers Standard Gage)
