CHS 273x6 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 273x6 steel profile weighs 39.5 kg/m (26.54 lb/ft). Cross-sectional area: 5,032.831 mm². Moment of inertia Ix = 4,487.084 cm⁴, Iy = 4,487.084 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 6 mm ≈ 4 gauge (Manufacturers Standard Gage)
