SHS 100x100x2.5 Acindar · Weight & Dimensions

Acindar, 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 13 (México) · Caño estructural 100x100 (Argentina)

The SHS 100x100x2.5 steel profile weighs 7.5 kg/m (5.06 lb/ft), has a depth of 100 mm (3.94 in), flange width 100 mm (3.94 in). Cross-sectional area: 958.905 mm². Moment of inertia Ix = 150.631 cm⁴, Iy = 150.631 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2.5 mm ≈ 12 gauge (Manufacturers Standard Gage)
