CHS 70x14 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 70x14 steel profile weighs 19.3 kg/m (12.99 lb/ft). Cross-sectional area: 2,463.009 mm². Moment of inertia Ix = 102.584 cm⁴, Iy = 102.584 cm⁴.
