SHS 76x76x7.9 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 76x76 (México) · Caño estructural 76x76 (Argentina)

The SHS 76x76x7.9 steel profile weighs 15.8 kg/m (10.60 lb/ft), has a depth of 76 mm (2.99 in), flange width 76 mm (2.99 in). Cross-sectional area: 1,991.24 mm². Moment of inertia Ix = 147.233 cm⁴, Iy = 147.233 cm⁴.
