SHS 140x140x6.4 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 140x140 cal 3 (México) · Caño estructural 140x140 (Argentina)

The SHS 140x140x6.4 steel profile weighs 26.0 kg/m (17.49 lb/ft), has a depth of 140 mm (5.51 in), flange width 140 mm (5.51 in). Cross-sectional area: 3,314.679 mm². Moment of inertia Ix = 969.888 cm⁴, Iy = 969.888 cm⁴.
