HSS 102x51x3.2
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 102x51x3.2 steel profile weighs 6.9 kg/m (4.61 lb/ft), has a depth of 101.6 mm (4.00 in), flange width 50.8 mm (2.00 in). Cross-sectional area: 878.4 mm². Moment of inertia Ix = 117.79 cm⁴, Iy = 39.36 cm⁴.
