CHS 165.1x4.8 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 165.1x4.8 steel profile weighs 19.0 kg/m (12.77 lb/ft). Cross-sectional area: 2,417.267 mm². Moment of inertia Ix = 777.125 cm⁴, Iy = 777.125 cm⁴.

Cross-section (not to scale)

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