SHS 100x100x11.1 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 100x100x11.1 steel profile weighs 28.5 kg/m (19.15 lb/ft), has a depth of 100 mm (3.94 in), flange width 100 mm (3.94 in). Cross-sectional area: 3,629.867 mm². Moment of inertia Ix = 455.542 cm⁴, Iy = 455.542 cm⁴.
