SHS 72x72x4 Tata Steel · Weight & Dimensions

Tata Steel, 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 72x72 cal 8 (México) · Caño estructural 72x72 (Argentina)

The SHS 72x72x4 steel profile weighs 8.2 kg/m (5.52 lb/ft), has a depth of 72 mm (2.83 in), flange width 72 mm (2.83 in). Cross-sectional area: 1,046.796 mm². Moment of inertia Ix = 79.025 cm⁴, Iy = 79.025 cm⁴.
