CHS 139.7x4.8 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 139.7x4.8 steel profile weighs 15.9 kg/m (10.71 lb/ft). Cross-sectional area: 2,034.244 mm². Moment of inertia Ix = 463.326 cm⁴, Iy = 463.326 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 4.8 mm ≈ 7 gauge (Manufacturers Standard Gage)
