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 508x508x12.7 steel profile weighs 170.0 kg/m (114.24 lb/ft), has a depth of 508 mm (20.00 in), flange width 508 mm (20.00 in). Cross-sectional area: 23,420.6 mm². Moment of inertia Ix = 96,162.68 cm⁴, Iy = 96,162.68 cm⁴.
