Cold Formed Welded Structural Hollow Sections are formed at ambient temperatures and are produced in accordance with standard EN 10219-1: 2006. There are more and more manufacturers of cold-formed hollow sections, which makes their products more widely used. In Germany, hot-worked structural hollow profile (HFSHS) products are usually 24% to 54% more expensive than cold-formed products.
