SHS 80x80x3.6 Tata Steel Celsius · Weight & Dimensions

Tata Steel Celsius · 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 80x80 (México) · Caño estructural 80x80 (Argentina)

The SHS 80x80x3.6 steel profile weighs 8.5 kg/m (5.73 lb/ft), has a depth of 80 mm (3.15 in), flange width 80 mm (3.15 in). Cross-sectional area: 1,077.91 mm². Moment of inertia Ix = 103.855 cm⁴, Iy = 103.855 cm⁴.
