SHS 70x70x6.3 Tuboeuropa · Weight & Dimensions

Tuboeuropa, cold-formed sections · 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 4 (México) · Caño estructural 70x70 (Argentina)

The SHS 70x70x6.3 steel profile weighs 11.5 kg/m (7.75 lb/ft), has a depth of 70 mm (2.76 in), flange width 70 mm (2.76 in). Cross-sectional area: 1,468.959 mm². Moment of inertia Ix = 93.775 cm⁴, Iy = 93.775 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 6.3 mm ≈ 3 gauge (Manufacturers Standard Gage)
