CHS 165.1x5.4 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 165.1x5.4 steel profile weighs 21.3 kg/m (14.29 lb/ft). Cross-sectional area: 2,709.247 mm². Moment of inertia Ix = 864.698 cm⁴, Iy = 864.698 cm⁴.

Cross-section (not to scale)

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