Before the construction of even the simplest and at first glance strong structures, design work is necessary. When compiling the project, the necessary parameters of the supporting structures are calculated, which ensure prolonged operation and compliance with the safety standards of the built building or structure. Before installation, you must first manufacture or purchase the necessary elements of metal structures. Installation should only be performed by certified specialists. In the manufacturing process or during the installation, parts of the structure must undergo anti -corrosion processing, which ensures the stability of the metal to the aggressive effect of the external environment and the long -term operation of the structure. Even galvanized parts can be corroded over time if they are outside. The installation of metal structures provides for the presence of a special base or foundation, to which the structural elements are fixed. Metal structures are also often used for decorative purposes: installation of sites, stairs, handrails, grilles. In such works, safety requirements are much lower, however, they also require the creation of project documentation. The use of metal structures as a frame for the subsequent installation of sandwich panels allows you to build large buildings in just a few weeks. Also, the installed metal frame can be sheathed with wood and other materials. Almost all modern non -residential buildings (shops, shopping centers, car dealerships, etc.) made using metal frames and special panels.
