Rectangular 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 rectangular cross-section is particularly efficient when bending loads act predominantly along one axis, allowing designers to optimise material use without sacrificing strength.
