SHS 91.5x91.5x4.5 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 91.5x91.5 cal 6 (México) · Caño estructural 91.5x91.5 (Argentina)

The SHS 91.5x91.5x4.5 steel profile weighs 11.9 kg/m (7.98 lb/ft), has a depth of 91.5 mm (3.60 in), flange width 91.5 mm (3.60 in). Cross-sectional area: 1,513.852 mm². Moment of inertia Ix = 187.574 cm⁴, Iy = 187.574 cm⁴.
