SHS 89x89x4 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 8 (México) · Caño estructural 89x89 (Argentina)

The SHS 89x89x4 steel profile weighs 10.2 kg/m (6.86 lb/ft), has a depth of 89 mm (3.50 in), flange width 89 mm (3.50 in). Cross-sectional area: 1,318.796 mm². Moment of inertia Ix = 156.249 cm⁴, Iy = 156.249 cm⁴.
