SHS 64x64x6.4 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 64x64 cal 3 (México) · Caño estructural 64x64 (Argentina)

The SHS 64x64x6.4 steel profile weighs 10.6 kg/m (7.11 lb/ft), has a depth of 64 mm (2.52 in), flange width 64 mm (2.52 in). Cross-sectional area: 1,369.079 mm². Moment of inertia Ix = 72.579 cm⁴, Iy = 72.579 cm⁴.
