Thermal diffusion galvanizing products is a cost-effective investment because the diffusion galvanised coating offers durable protection against corrosion and wear and tear. The long service life has been proven for decades in  industrial  and marine applications.

The service life of a number of zinc coatings in a variety of atmospheric environments is described in EN ISO 14713. The expected service life of a thermal diffusion galvanized coating of, on average, 35 µm is more than twenty years if used in an urban environment.

The corrosion resistance can be substantially increased through the application of a top coating to a diffusion galvanised surface. In salt spray tests, the ArmorGalv®  system produces results of more than 2,000 hours.
