CHS 194x16 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 194x16 steel profile weighs 70.2 kg/m (47.20 lb/ft). Cross-sectional area: 8,947.256 mm². Moment of inertia Ix = 3,572.192 cm⁴, Iy = 3,572.192 cm⁴.
