SHS 180x180x6.3 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 180x180 cal 4 (México) · Caño estructural 180x180 (Argentina)

The SHS 180x180x6.3 steel profile weighs 33.3 kg/m (22.38 lb/ft), has a depth of 180 mm (7.09 in), flange width 180 mm (7.09 in). Cross-sectional area: 4,240.959 mm². Moment of inertia Ix = 2,095.649 cm⁴, Iy = 2,095.649 cm⁴.
