Cold And Hot Formed Circular Hollow Sections
Circular Hollow Sections (CHS) include both cold-formed and hot-finished tubular profiles. Cold-formed sections are produced at ambient temperatures and are cost-effective for many applications, while hot-finished sections are formed at elevated temperatures, offering uniform strength in all directions and superior torsional resistance.
