Are galvanized ground rods suitable for grounding lightning protection systems?

Galvanized ground rods generally are not suitable for grounding lightning protection systems due to their susceptibility to corrosion over time, which can hinder their effectiveness. The performance of a grounding system is crucial because it must provide a low-resistance path for lightning energy to dissipate safely into the ground. While galvanized rods can be used in other applications, they may not provide the long-term reliability and conductivity needed in lightning protection systems.

Copper or copper-clad ground rods are often preferred in these systems because they offer better resistance to corrosion and superior conductivity. These materials ensure that the lightning protection system remains effective and reliable throughout its operational lifespan. By using materials that can withstand the erosive nature of grounding environments, you enhance the overall safety and functionality of the lightning protection installation.
