SHS 55x55x1.5 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 55x55 cal 16 (México) · Caño estructural 55x55 (Argentina)

The SHS 55x55x1.5 steel profile weighs 2.5 kg/m (1.66 lb/ft), has a depth of 55 mm (2.17 in), flange width 55 mm (2.17 in). Cross-sectional area: 315.206 mm². Moment of inertia Ix = 14.896 cm⁴, Iy = 14.896 cm⁴.
