SHS 120x120x6 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 4 (México) · Caño estructural 120x120 (Argentina)

The SHS 120x120x6 steel profile weighs 20.8 kg/m (13.94 lb/ft), has a depth of 120 mm (4.72 in), flange width 120 mm (4.72 in). Cross-sectional area: 2,643.292 mm². Moment of inertia Ix = 562.157 cm⁴, Iy = 562.157 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 6 mm ≈ 4 gauge (Manufacturers Standard Gage)
