SHS 300x300x12 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 steel profile weighs 104.0 kg/m (69.89 lb/ft), has a depth of 300 mm (11.81 in), flange width 300 mm (11.81 in). Cross-sectional area: 13,205.947 mm². Moment of inertia Ix = 17,767.354 cm⁴, Iy = 17,767.354 cm⁴.
