CHS 89x3 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 89x3 steel profile weighs 6.4 kg/m (4.27 lb/ft). Cross-sectional area: 810.531 mm². Moment of inertia Ix = 75.025 cm⁴, Iy = 75.025 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3 mm ≈ 11 gauge (Manufacturers Standard Gage)
