Solid Copper Grounding Rod - Internally Threaded HEX solid copper earth rods are made from 99.9% pure electrolytic copper. Solid copper rods offers greater resistance to corrosion. They are ideally used in applications where soil conditions are very aggressive, for eg. soil with high salt content.

Solid Copper Ground Rods Solid copper ground rods are very corrosion resistant (except when faced with salts) and are also very conductive. However, you will rarely see solid copper outside of the Middle East or similar environments because copper is a ductile, soft metal that often bends when driven into soil other than sand.
