SHS 89x89x3.2 IMCA · Weight & Dimensions

IMCA, 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 89x89 cal 11 (México) · Caño estructural 89x89 (Argentina)

The SHS 89x89x3.2 steel profile weighs 8.3 kg/m (5.60 lb/ft), has a depth of 89 mm (3.50 in), flange width 89 mm (3.50 in). Cross-sectional area: 1,071.87 mm². Moment of inertia Ix = 129.856 cm⁴, Iy = 129.856 cm⁴.
