SHS 180x180x7 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 180x180 (México) · Caño estructural 180x180 (Argentina)

The SHS 180x180x7 steel profile weighs 37.0 kg/m (24.88 lb/ft), has a depth of 180 mm (7.09 in), flange width 180 mm (7.09 in). Cross-sectional area: 4,717.814 mm². Moment of inertia Ix = 2,321.035 cm⁴, Iy = 2,321.035 cm⁴.
