SHS 65x65x3.5 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 11 (México) · Caño estructural 65x65 (Argentina)

The SHS 65x65x3.5 steel profile weighs 6.5 kg/m (4.37 lb/ft), has a depth of 65 mm (2.56 in), flange width 65 mm (2.56 in). Cross-sectional area: 829.454 mm². Moment of inertia Ix = 51.256 cm⁴, Iy = 51.256 cm⁴.
