CHS 114x3 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 114x3 steel profile weighs 8.2 kg/m (5.52 lb/ft). Cross-sectional area: 1,046.15 mm². Moment of inertia Ix = 161.238 cm⁴, Iy = 161.238 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 3 mm ≈ 11 gauge (Manufacturers Standard Gage)
