Corrosion in Aboveground Structures

The process of corrosion in aboveground structures is very similar to corrosion in underground structures, requiring the presence of an electrolyte, which, in most atmospheric situations, is humidity or rainwater.  Cathodic protection, however, is useless for the protection of aboveground structures due to the lack of a continuous electrolyte between the anodes and the structure and only a good maintenance program using coatings or corrosion inhibitors can eliminate or reduce corrosion in those areas in which the environment is corrosive, such as in areas close to the ocean.
PCA Engineering offers a number of specialty paints and corrosion inhibitors for above ground structures.  Select the link above entitled “Protective Coatings & Inhibitors”, and variety of options are made available.  Send us a quick email with the Quick Question link at the bottom of the home page, describe your application, and we will reply with a no-obligation, on-line recommendation and quotation.
