SHS 160x160x6.4 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 160x160 cal 3 (México) · Caño estructural 160x160 (Argentina)

The SHS 160x160x6.4 steel profile weighs 30.0 kg/m (20.19 lb/ft), has a depth of 160 mm (6.30 in), flange width 160 mm (6.30 in). Cross-sectional area: 3,826.679 mm². Moment of inertia Ix = 1,483.418 cm⁴, Iy = 1,483.418 cm⁴.
