SHS 100x100x3.5 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 100x100 cal 11 (México) · Caño estructural 100x100 (Argentina)

The SHS 100x100x3.5 steel profile weighs 10.3 kg/m (6.96 lb/ft), has a depth of 100 mm (3.94 in), flange width 100 mm (3.94 in). Cross-sectional area: 1,319.454 mm². Moment of inertia Ix = 202.28 cm⁴, Iy = 202.28 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 3.5 mm ≈ 10 gauge (Manufacturers Standard Gage)
