SHS 100x100x4.4 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 100x100 (México) · Caño estructural 100x100 (Argentina)

The SHS 100x100x4.4 steel profile weighs 12.8 kg/m (8.62 lb/ft), has a depth of 100 mm (3.94 in), flange width 100 mm (3.94 in). Cross-sectional area: 1,632.704 mm². Moment of inertia Ix = 244.788 cm⁴, Iy = 244.788 cm⁴.
