CHS 48.3x2.9 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 48.3x2.9 steel profile weighs 3.2 kg/m (2.18 lb/ft). Cross-sectional area: 413.622 mm². Moment of inertia Ix = 10.7 cm⁴, Iy = 10.7 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2.9 mm ≈ 11 gauge (Manufacturers Standard Gage)
