SHS 65x65x4 Hiasa · Weight & Dimensions

Hiasa, 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 65x65 cal 8 (México) · Caño estructural 65x65 (Argentina)

The SHS 65x65x4 steel profile weighs 7.3 kg/m (4.93 lb/ft), has a depth of 65 mm (2.56 in), flange width 65 mm (2.56 in). Cross-sectional area: 934.796 mm². Moment of inertia Ix = 56.641 cm⁴, Iy = 56.641 cm⁴.
