SHS 90x90x2.5 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 90x90 cal 13 (México) · Caño estructural 90x90 (Argentina)

The SHS 90x90x2.5 steel profile weighs 6.7 kg/m (4.53 lb/ft), has a depth of 90 mm (3.54 in), flange width 90 mm (3.54 in). Cross-sectional area: 858.905 mm². Moment of inertia Ix = 108.554 cm⁴, Iy = 108.554 cm⁴.
