SHS 76x76x6.4 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 cal 3 (México) · Caño estructural 76x76 (Argentina)

The SHS 76x76x6.4 steel profile weighs 13.1 kg/m (8.82 lb/ft), has a depth of 76 mm (2.99 in), flange width 76 mm (2.99 in). Cross-sectional area: 1,676.279 mm². Moment of inertia Ix = 130.826 cm⁴, Iy = 130.826 cm⁴.
