Fire-retardant powder coatings are used to protect metal structures from exposure to high temperatures and fire. These coatings are applied in the form of powder, which then melts and forms a strong, heat-resistant layer on the metal surface. Such a layer effectively slows down the heating of the material during a fire, preventing its destruction and maintaining strength for a long time. Fire-retardant powder coatings significantly reduce the risk of damage to structures in the event of a fire, increasing the safety of buildings and structures. They are widely used to protect metal structures, such as building frames, metal elements of bridges and industrial facilities.
