SHS 70x70x4 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 70x70 cal 8 (México) · Caño estructural 70x70 (Argentina)

The SHS 70x70x4 steel profile weighs 8.2 kg/m (5.48 lb/ft), has a depth of 70 mm (2.76 in), flange width 70 mm (2.76 in). Cross-sectional area: 1,028.531 mm². Moment of inertia Ix = 73.763 cm⁴, Iy = 73.763 cm⁴.

Cross-section (not to scale)

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