SHS 50x50x4.8 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 50x50 cal 6 (México) · Caño estructural 50x50 (Argentina)

The SHS 50x50x4.8 steel profile weighs 6.3 kg/m (4.27 lb/ft), has a depth of 50 mm (1.97 in), flange width 50 mm (1.97 in). Cross-sectional area: 808.507 mm². Moment of inertia Ix = 26.451 cm⁴, Iy = 26.451 cm⁴.
