CHS 127x3 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 127x3 steel profile weighs 9.2 kg/m (6.16 lb/ft). Cross-sectional area: 1,168.672 mm². Moment of inertia Ix = 224.75 cm⁴, Iy = 224.75 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3 mm ≈ 11 gauge (Manufacturers Standard Gage)
