Jeff, I am not an outdoor installation expert, but the following two things came to my mind when I saw your question: - A sacrificial anode would be a benefit for the installation. - An Impressed Current Cathodic Protection would be better for large structures (and is used e.g. for pipelines). The use of -48V in telecom installations was introduced to limit corrosion. Best regards, Michael

Group/ Outdoor Telecom Equipment Experts, We are developing a very large telecom product/structure that will reside in an outdoor environment. We need to obtain a greater than 15 years high durability design life for the steel structure. What are the benefits/costs between treating steel for corrosion using either hot-dipped galvanized, electroplated galvanized as opposed to a paint treatment as prescribed by ISO 12944/High Durability for C4 environment? Thanks in advance!
