CHS 48.3x6.3 Tata Steel Celsius · Weight & Dimensions

Tata Steel Celsius · 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 48.3x6.3 steel profile weighs 6.5 kg/m (4.39 lb/ft). Cross-sectional area: 831.265 mm². Moment of inertia Ix = 18.742 cm⁴, Iy = 18.742 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 6.3 mm ≈ 3 gauge (Manufacturers Standard Gage)
