CHS 180x45 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)
