SHS 100x100x6.4 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 cal 3 (México) · Caño estructural 100x100 (Argentina)

The SHS 100x100x6.4 steel profile weighs 18.0 kg/m (12.08 lb/ft), has a depth of 100 mm (3.94 in), flange width 100 mm (3.94 in). Cross-sectional area: 2,290.679 mm². Moment of inertia Ix = 326.436 cm⁴, Iy = 326.436 cm⁴.
