SHS 300x300x12.5 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 300x300 (México) · Caño estructural 300x300 (Argentina)

The SHS 300x300x12.5 steel profile weighs 108.0 kg/m (72.58 lb/ft), has a depth of 300 mm (11.81 in), flange width 300 mm (11.81 in). Cross-sectional area: 13,704.369 mm². Moment of inertia Ix = 18,348.135 cm⁴, Iy = 18,348.135 cm⁴.
