CHS 76.1x4.5 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 76.1x4.5 steel profile weighs 7.9 kg/m (5.33 lb/ft). Cross-sectional area: 1,012.221 mm². Moment of inertia Ix = 65.121 cm⁴, Iy = 65.121 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 4.5 mm ≈ 7 gauge (Manufacturers Standard Gage)
