Yes, copper bonded earthing rods are widely used and highly recommended for lightning protection systems. These rods are manufactured by molecularly bonding a thick layer of 99.9% pure electrolytic copper onto a high-tensile low-carbon steel core, combining the conductivity of copper with the strength and durability of steel. This design ensures the rod can be deep-driven into the gro... https://www.pioneerpowers.com/copper-bonded-earth-rod.php
