SHS 300x300x17.5 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 300x300 (México) · Caño estructural 300x300 (Argentina)

The SHS 300x300x17.5 steel profile weighs 153.0 kg/m (102.82 lb/ft), has a depth of 300 mm (11.81 in), flange width 300 mm (11.81 in). Cross-sectional area: 19,249.226 mm². Moment of inertia Ix = 25,285.479 cm⁴, Iy = 25,285.479 cm⁴.
