CHS 146x4 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 146x4 steel profile weighs 14.0 kg/m (9.41 lb/ft). Cross-sectional area: 1,784.425 mm². Moment of inertia Ix = 450.121 cm⁴, Iy = 450.121 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 4 mm ≈ 8 gauge (Manufacturers Standard Gage)
