SHS 40x40x3.6 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 40x40 (México) · Caño estructural 40x40 (Argentina)

The SHS 40x40x3.6 steel profile weighs 4.0 kg/m (2.69 lb/ft), has a depth of 40 mm (1.57 in), flange width 40 mm (1.57 in). Cross-sectional area: 501.91 mm². Moment of inertia Ix = 10.873 cm⁴, Iy = 10.873 cm⁴.
