SHS 38x38x2.5 Hiasa · Weight & Dimensions

Hiasa, 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 38x38 cal 13 (México) · Caño estructural 38x38 (Argentina)

The SHS 38x38x2.5 steel profile weighs 2.7 kg/m (1.79 lb/ft), has a depth of 38 mm (1.50 in), flange width 38 mm (1.50 in). Cross-sectional area: 338.905 mm². Moment of inertia Ix = 6.942 cm⁴, Iy = 6.942 cm⁴.

Cross-section (not to scale)

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