CHS 133x32 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 133x32 steel profile weighs 79.7 kg/m (53.57 lb/ft). Cross-sectional area: 10,153.627 mm². Moment of inertia Ix = 1,424.681 cm⁴, Iy = 1,424.681 cm⁴.
