CHS 168x6 GOST · Weight & Dimensions

GOST, 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 168x6 steel profile weighs 24.0 kg/m (16.11 lb/ft). Cross-sectional area: 3,053.628 mm². Moment of inertia Ix = 1,003.117 cm⁴, Iy = 1,003.117 cm⁴.

Cross-section (not to scale)

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