SHS 120x120x3 SAISC · Weight & Dimensions
SAISC, cold-formed sections · 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.
Also known as: PTR 120x120 cal 11 (México) · Caño estructural 120x120 (Argentina)
The SHS 120x120x3 steel profile weighs 10.8 kg/m (7.28 lb/ft), has a depth of 120 mm (4.72 in), flange width 120 mm (4.72 in). Cross-sectional area: 1,380.823 mm². Moment of inertia Ix = 312.347 cm⁴, Iy = 312.347 cm⁴.
