CHS 140x5 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 140x5 steel profile weighs 16.6 kg/m (11.19 lb/ft). Cross-sectional area: 2,120.575 mm². Moment of inertia Ix = 483.756 cm⁴, Iy = 483.756 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 5 mm ≈ 6 gauge (Manufacturers Standard Gage)
