SHS 400x400x8 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 400x400 (México) · Caño estructural 400x400 (Argentina)

The SHS 400x400x8 steel profile weighs 97.9 kg/m (65.79 lb/ft), has a depth of 400 mm (15.75 in), flange width 400 mm (15.75 in). Cross-sectional area: 12,434.124 mm². Moment of inertia Ix = 31,708.221 cm⁴, Iy = 31,708.221 cm⁴.
