SHS 50x50x2.5 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 50x50 cal 13 (México) · Caño estructural 50x50 (Argentina)

The SHS 50x50x2.5 steel profile weighs 3.6 kg/m (2.42 lb/ft), has a depth of 50 mm (1.97 in), flange width 50 mm (1.97 in). Cross-sectional area: 458.905 mm². Moment of inertia Ix = 16.944 cm⁴, Iy = 16.944 cm⁴.

Cross-section (not to scale)

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