CHS 194x7 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 194x7 steel profile weighs 32.3 kg/m (21.69 lb/ft). Cross-sectional area: 4,112.345 mm². Moment of inertia Ix = 1,800.076 cm⁴, Iy = 1,800.076 cm⁴.
