SHS 350x350x17.5 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 350x350x17.5 steel profile weighs 180.0 kg/m (120.96 lb/ft), has a depth of 350 mm (13.78 in), flange width 350 mm (13.78 in). Cross-sectional area: 22,749.226 mm². Moment of inertia Ix = 41,470.902 cm⁴, Iy = 41,470.902 cm⁴.
