SHS 90x90x6.3 Tata Steel Celsius · Weight & Dimensions

Tata Steel Celsius · 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 90x90 cal 4 (México) · Caño estructural 90x90 (Argentina)

The SHS 90x90x6.3 steel profile weighs 16.2 kg/m (10.89 lb/ft), has a depth of 90 mm (3.54 in), flange width 90 mm (3.54 in). Cross-sectional area: 2,041.1 mm². Moment of inertia Ix = 234.778 cm⁴, Iy = 234.778 cm⁴.
