CHS 63x6 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 63x6 steel profile weighs 8.4 kg/m (5.66 lb/ft). Cross-sectional area: 1,074.425 mm². Moment of inertia Ix = 44.119 cm⁴, Iy = 44.119 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 6 mm ≈ 4 gauge (Manufacturers Standard Gage)
