SHS 28x28x1.2 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 28x28x1.2 steel profile weighs 1.0 kg/m (0.66 lb/ft), has a depth of 28 mm (1.10 in), flange width 28 mm (1.10 in). Cross-sectional area: 124.932 mm². Moment of inertia Ix = 1.473 cm⁴, Iy = 1.473 cm⁴.
