SHS 90x90x4 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 8 (México) · Caño estructural 90x90 (Argentina)

The SHS 90x90x4 steel profile weighs 10.7 kg/m (7.19 lb/ft), has a depth of 90 mm (3.54 in), flange width 90 mm (3.54 in). Cross-sectional area: 1,348.531 mm². Moment of inertia Ix = 164.652 cm⁴, Iy = 164.652 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 4 mm ≈ 8 gauge (Manufacturers Standard Gage)
