SHS 38.1x38.1x2.8 Hylsa · Weight & Dimensions

Hylsa, 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 38.1x38.1 cal 13 (México) · Caño estructural 38.1x38.1 (Argentina)

The SHS 38.1x38.1x2.8 steel profile weighs 2.9 kg/m (1.98 lb/ft), has a depth of 38.1 mm (1.50 in), flange width 38.1 mm (1.50 in). Cross-sectional area: 375.17 mm². Moment of inertia Ix = 7.571 cm⁴, Iy = 7.571 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2.8 mm ≈ 12 gauge (Manufacturers Standard Gage)
