SHS 350x350x8 Tata Steel Hybox · Weight & Dimensions

Tata Steel Hybox · 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 84.2 kg/m (56.58 lb/ft), has a depth of 350 mm (13.78 in), flange width 350 mm (13.78 in). Cross-sectional area: 10,724.248 mm². Moment of inertia Ix = 20,680.7 cm⁴, Iy = 20,680.7 cm⁴.
