CHS 146x5 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 146x5 steel profile weighs 17.4 kg/m (11.69 lb/ft). Cross-sectional area: 2,214.823 mm². Moment of inertia Ix = 551.103 cm⁴, Iy = 551.103 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 5 mm ≈ 6 gauge (Manufacturers Standard Gage)
