CHS 146x6 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 146x6 steel profile weighs 20.7 kg/m (13.92 lb/ft). Cross-sectional area: 2,638.938 mm². Moment of inertia Ix = 647.727 cm⁴, Iy = 647.727 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 6 mm ≈ 4 gauge (Manufacturers Standard Gage)
