Columns of the “KRS” type – Steel conical round columns made from one piece by longitudinal welding, “plasma” welding (invisible welding), from one piece, without extensions. They are produced in two basic variants, depending on the method of installation – type KRS-A , with an anchor plate (installation over anchors that have been previously concreted) or the KRS-U type, the so-called “burying”, where a part of the column is buried in the foundation, during the construction and concreting of the foundation.
