SHS 50x50x5.2 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 50x50 (México) · Caño estructural 50x50 (Argentina)

The SHS 50x50x5.2 steel profile weighs 6.8 kg/m (4.55 lb/ft), has a depth of 50 mm (1.97 in), flange width 50 mm (1.97 in). Cross-sectional area: 862.206 mm². Moment of inertia Ix = 27.589 cm⁴, Iy = 27.589 cm⁴.
