CHS 180x28 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 180x28 steel profile weighs 105.0 kg/m (70.53 lb/ft). Cross-sectional area: 13,370.618 mm². Moment of inertia Ix = 3,992.467 cm⁴, Iy = 3,992.467 cm⁴.
