SHS 400x400x12.5 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 400x400 (México) · Caño estructural 400x400 (Argentina)

The SHS 400x400x12.5 steel profile weighs 147.0 kg/m (98.78 lb/ft), has a depth of 400 mm (15.75 in), flange width 400 mm (15.75 in). Cross-sectional area: 18,704.369 mm². Moment of inertia Ix = 45,876.538 cm⁴, Iy = 45,876.538 cm⁴.
