SHS 130x130x6.4 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 130x130 cal 3 (México) · Caño estructural 130x130 (Argentina)

The SHS 130x130x6.4 steel profile weighs 24.0 kg/m (16.13 lb/ft), has a depth of 130 mm (5.12 in), flange width 130 mm (5.12 in). Cross-sectional area: 3,058.679 mm². Moment of inertia Ix = 764.913 cm⁴, Iy = 764.913 cm⁴.
