HSS 127x127x4.8
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 127x127x4.8 steel profile weighs 17.3 kg/m (11.63 lb/ft), has a depth of 127 mm (5.00 in), flange width 127 mm (5.00 in). Cross-sectional area: 2,205 mm². Moment of inertia Ix = 552.22 cm⁴, Iy = 552.22 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 4.5 mm ≈ 7 gauge (Manufacturers Standard Gage)
