SHS 38.1x38.1x4 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 8 (México) · Caño estructural 38.1x38.1 (Argentina)

The SHS 38.1x38.1x4 steel profile weighs 3.9 kg/m (2.61 lb/ft), has a depth of 38.1 mm (1.50 in), flange width 38.1 mm (1.50 in). Cross-sectional area: 504.396 mm². Moment of inertia Ix = 9.346 cm⁴, Iy = 9.346 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 4 mm ≈ 8 gauge (Manufacturers Standard Gage)
