SHS 28x28x1 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 28x28 cal 18 (México) · Caño estructural 28x28 (Argentina)

The SHS 28x28x1 steel profile weighs 0.8 kg/m (0.56 lb/ft), has a depth of 28 mm (1.10 in), flange width 28 mm (1.10 in). Cross-sectional area: 105.425 mm². Moment of inertia Ix = 1.265 cm⁴, Iy = 1.265 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 1 mm ≈ 18 gauge (Manufacturers Standard Gage)
