CHS 76.1x3 Tata Steel Hybox · Weight & Dimensions

Tata Steel Hybox · 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 76.1x3 steel profile weighs 5.4 kg/m (3.64 lb/ft). Cross-sectional area: 688.951 mm². Moment of inertia Ix = 46.096 cm⁴, Iy = 46.096 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 3 mm ≈ 11 gauge (Manufacturers Standard Gage)
