What are grounding rods commonly made of?

Grounding rods are commonly made of steel or copper because these materials have excellent conductivity properties that enable them to effectively conduct electrical currents, providing a direct and low-resistance path to the ground. This is essential for safety measures in electrical systems, as grounding helps to prevent electrical shocks and ensure that excess voltage is safely dissipated into the earth.

Steel is often used in the construction of grounding rods because of its strength and durability, while copper is favored for its superior electrical conductivity. Copper rods are typically more resistant to corrosion, making them suitable for long-term use in various environmental conditions. The combination of these materials in grounding rod applications ensures effective grounding and enhances the overall safety and reliability of electrical systems.
