SHS 90x90x5 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 90x90 cal 6 (México) · Caño estructural 90x90 (Argentina)

The SHS 90x90x5 steel profile weighs 12.8 kg/m (8.60 lb/ft), has a depth of 90 mm (3.54 in), flange width 90 mm (3.54 in). Cross-sectional area: 1,635.619 mm². Moment of inertia Ix = 192.933 cm⁴, Iy = 192.933 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 5 mm ≈ 6 gauge (Manufacturers Standard Gage)
