In order for metal structures to last for the period specified by the manufacturer, they must be treated with a special anti-corrosion compound. Although metal has quite high strength, it is still susceptible to the harmful effects of moisture compared to many other materials.

The role of the primer—or what is known as a corrosion inhibitor—is to prepare the surface for subsequent painting. Thanks to the primer, the surface’s adhesive properties are enhanced, which improves the paint’s adhesion to it. The primer not only serves as a preparatory layer but also acts as the metal’s primary protective barrier against the adverse effects of the external environment.
