Galvanize It! Online Seminar


Structures throughout the power system are exposed to various corrosive environments and in some cases, the type of generation itself affects the environment. From blazing sun and temperatures to UV rays, the hot-dip galvanized coating can withstand many extreme environments. With the long design life of power structures, maintenance-free longevity is paramount.

There are four main macro environments power structures are exposed to and each has different factors that dictate the corrosivity to galvanized steel. Some structures, such as distribution poles, are often exposed to more than one of these environments at the same time. The next pages will examine galvanizing’s longevity in each of the following:

  • In the Atmosphere
  • At Ground Level
  • In Soil
  • In Moisture-Rich Environments
