Our Copper Bonded Earthing Rods are made from high tensile low carbon steel that complies with BS 4360 grade 43A. Each rod is made by molecularly bonding 99.9 % pure electrolytic copper. Moreover, to prevent oxidation of copper bonding, these rods are further treated with benzol - triozole derivatives. The threads on the rods are formed by roll threading process, which gives an extra strength to the threads while eliminating the risk of chipping of threads on driving the rod in the ground.
