SHS 350x350x6.3 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 350x350 cal 4 (México) · Caño estructural 350x350 (Argentina)

The SHS 350x350x6.3 steel profile weighs 66.9 kg/m (44.96 lb/ft), has a depth of 350 mm (13.78 in), flange width 350 mm (13.78 in). Cross-sectional area: 8,524.959 mm². Moment of inertia Ix = 16,644.633 cm⁴, Iy = 16,644.633 cm⁴.
