HSS 203x203x6.4
AISC — Square Hollow Section
Square Hollow Sections (SHS) are tubular profiles with equal sides, ideal for columns and compression members due to their uniform buckling resistance in all directions.
The HSS 203x203x6.4 steel profile weighs 35.8 kg/m (24.06 lb/ft), has a depth of 203.2 mm (8.00 in), flange width 203.2 mm (8.00 in). Cross-sectional area: 4,656.3 mm². Moment of inertia Ix = 3,023.64 cm⁴, Iy = 3,023.64 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 5.9 mm ≈ 4 gauge (Manufacturers Standard Gage)
