SHS 50.8x50.8x4 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 50.8x50.8 cal 8 (México) · Caño estructural 50.8x50.8 (Argentina)

The SHS 50.8x50.8x4 steel profile weighs 5.5 kg/m (3.68 lb/ft), has a depth of 50.8 mm (2.00 in), flange width 50.8 mm (2.00 in). Cross-sectional area: 707.596 mm². Moment of inertia Ix = 25.037 cm⁴, Iy = 25.037 cm⁴.

Cross-section (not to scale)

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