SHS 350x350x8 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 350x350 (México) · Caño estructural 350x350 (Argentina)

The SHS 350x350x8 steel profile weighs 85.4 kg/m (57.39 lb/ft), has a depth of 350 mm (13.78 in), flange width 350 mm (13.78 in). Cross-sectional area: 10,834.124 mm². Moment of inertia Ix = 21,016.691 cm⁴, Iy = 21,016.691 cm⁴.
