Square profile pipes are mainly used in structures subject to significant mechanical loads and vibration: the assembly of metal frameworks and building enclosures, and the manufacture of various supports, columns, complex roofing systems, partitions and similar elements. The square cross-section offers high torsional rigidity and a flat outer surface that simplifies welding, bolting and surface finishing in fabricated assemblies.
