SHS 145x145x6.4 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 145x145 cal 3 (México) · Caño estructural 145x145 (Argentina)

The SHS 145x145x6.4 steel profile weighs 27.0 kg/m (18.16 lb/ft), has a depth of 145 mm (5.71 in), flange width 145 mm (5.71 in). Cross-sectional area: 3,442.679 mm². Moment of inertia Ix = 1,084.842 cm⁴, Iy = 1,084.842 cm⁴.
