SHS 140x140x4 GOST · Weight & Dimensions

GOST, 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 8 (México) · Caño estructural 140x140 (Argentina)

The SHS 140x140x4 steel profile weighs 16.8 kg/m (11.26 lb/ft), has a depth of 140 mm (5.51 in), flange width 140 mm (5.51 in). Cross-sectional area: 2,134.796 mm². Moment of inertia Ix = 651.616 cm⁴, Iy = 651.616 cm⁴.
