SHS 75x75x3 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 75x75 cal 11 (México) · Caño estructural 75x75 (Argentina)

The SHS 75x75x3 steel profile weighs 6.6 kg/m (4.44 lb/ft), has a depth of 75 mm (2.95 in), flange width 75 mm (2.95 in). Cross-sectional area: 840.823 mm². Moment of inertia Ix = 71.619 cm⁴, Iy = 71.619 cm⁴.
