SHS 125x125x5.2 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 125x125 (México) · Caño estructural 125x125 (Argentina)

The SHS 125x125x5.2 steel profile weighs 19.0 kg/m (12.77 lb/ft), has a depth of 125 mm (4.92 in), flange width 125 mm (4.92 in). Cross-sectional area: 2,422.206 mm². Moment of inertia Ix = 570.833 cm⁴, Iy = 570.833 cm⁴.
