Today, the use of metal structures is one of the best ways to construct buildings for any purpose, as they allow work to be completed in the shortest possible time. This applies not only to the simplest structures, but also to quite complex ones. Metal structures are widely used in construction because of their performance characteristics, i.e. long service life and robustness. The advantage of this material is that it does not require special equipment or a large number of people to install it, which reduces the final cost of the work. The mobility of the material makes it convenient to build with it, as the parts can be moved quickly and easily from one place to another when needed. In addition, they can be dismantled and reassembled many times without damaging the whole object.
