SHS 64x64x3.6 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 (México) · Caño estructural 64x64 (Argentina)

The SHS 64x64x3.6 steel profile weighs 6.5 kg/m (4.35 lb/ft), has a depth of 64 mm (2.52 in), flange width 64 mm (2.52 in). Cross-sectional area: 836.385 mm². Moment of inertia Ix = 49.801 cm⁴, Iy = 49.801 cm⁴.
