SHS 75x75x8.8 Açotubo · Weight & Dimensions

Açotubo, 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 (México) · Caño estructural 75x75 (Argentina)

The SHS 75x75x8.8 steel profile weighs 16.7 kg/m (11.24 lb/ft), has a depth of 75 mm (2.95 in), flange width 75 mm (2.95 in). Cross-sectional area: 2,130.815 mm². Moment of inertia Ix = 147.726 cm⁴, Iy = 147.726 cm⁴.
