SHS 190x190x6.4 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 190x190 cal 3 (México) · Caño estructural 190x190 (Argentina)

The SHS 190x190x6.4 steel profile weighs 36.1 kg/m (24.24 lb/ft), has a depth of 190 mm (7.48 in), flange width 190 mm (7.48 in). Cross-sectional area: 4,594.679 mm². Moment of inertia Ix = 2,551.071 cm⁴, Iy = 2,551.071 cm⁴.
