CHS 152x11 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 152x11 steel profile weighs 38.3 kg/m (25.70 lb/ft). Cross-sectional area: 4,872.61 mm². Moment of inertia Ix = 1,218.274 cm⁴, Iy = 1,218.274 cm⁴.
