SHS 90x90x1.6 Acindar · Weight & Dimensions

Acindar, 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 16 (México) · Caño estructural 90x90 (Argentina)

The SHS 90x90x1.6 steel profile weighs 4.4 kg/m (2.95 lb/ft), has a depth of 90 mm (3.54 in), flange width 90 mm (3.54 in). Cross-sectional area: 559.167 mm². Moment of inertia Ix = 72.393 cm⁴, Iy = 72.393 cm⁴.
