CHS 139.7x5.4 Tata Steel · Weight & Dimensions

Tata Steel, cold-formed sections · Circular Hollow Section

Circular Hollow Sections (CHS) are round tubular profiles with the most efficient cross-section for compression. Used for columns, trusses, and architectural structures.

Also known as: Caño estructural redondo (Argentina)

The CHS 139.7x5.4 steel profile weighs 17.9 kg/m (12.03 lb/ft). Cross-sectional area: 2,278.346 mm². Moment of inertia Ix = 514.497 cm⁴, Iy = 514.497 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 5.4 mm ≈ 6 gauge (Manufacturers Standard Gage)
