CHS 508x6.3 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 508x6.3 steel profile weighs 77.9 kg/m (52.35 lb/ft). Cross-sectional area: 9,929.663 mm². Moment of inertia Ix = 31,246.488 cm⁴, Iy = 31,246.488 cm⁴.

Cross-section (not to scale)

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