SHS 150x150x6.4 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 150x150 cal 3 (México) · Caño estructural 150x150 (Argentina)

The SHS 150x150x6.4 steel profile weighs 28.0 kg/m (18.84 lb/ft), has a depth of 150 mm (5.91 in), flange width 150 mm (5.91 in). Cross-sectional area: 3,570.679 mm². Moment of inertia Ix = 1,208.536 cm⁴, Iy = 1,208.536 cm⁴.
