Copper Bonded Rods are the ideal driven earth rod as they offer the installer an economical and efficient earth rod grounding system. Pure electrolyte copper is uniformly molecularly bonded into a high tensile steel core to a minimum thickness of 25 microns, thus ensuring excellent corrosion resistance and eliminating electrolytic action. The bonded rod helps in passing fault current on the ground. It is a part of earthing equipment. Copper bonded rods are coated with copper through the process called electroplating.
