HSS 203x152x6.4
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 203x152x6.4 steel profile weighs 31.0 kg/m (20.83 lb/ft), has a depth of 203.2 mm (8.00 in), flange width 152.4 mm (6.00 in). Cross-sectional area: 4,056.8 mm². Moment of inertia Ix = 2,440.1 cm⁴, Iy = 1,560.54 cm⁴.
