SHS 290x290x8.2 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 290x290 (México) · Caño estructural 290x290 (Argentina)

The SHS 290x290x8.2 steel profile weighs 71.2 kg/m (47.85 lb/ft), has a depth of 290 mm (11.42 in), flange width 290 mm (11.42 in). Cross-sectional area: 9,069.882 mm². Moment of inertia Ix = 11,887.45 cm⁴, Iy = 11,887.45 cm⁴.
