Metal Columns

Metal columns of buildings are the main part in the form carcasses of buildings made of metal structures. Metal columns are usually made of pipes and beams.

Steel is characterized by a high power, light weight, good general stiffness and strength as well as deformation characteristics, making it a perfect option for making columns for long span buildings. Column bases are usually fastened with bolts or firmly fixed to the foundation by concreting or welding to an insert. The top of the column is welded or bolted to the roof frame.

Columns are one of the key elements of buildings. Years of experience and continuous development allow us to offer you the metal structures of highest quality of Execution Class 2 (EXC2) in accordance with the requirements of EN 1090-2:2018+A1.
