Copper Bonded Grouding Rod
Copper Bonded Grouding Rod
Copper Bonded Grouding Earth Rod are made from low carbon steel of grade BS 970 or AISI 1018 with a high tensile strength of atleast 600 N/mm2. Low carbon steel core are molecularly bonded with 99.9% pure electrolytic copper. Perfectly bonded rod will last longer, drive easier and will not crack, Corrosion resistance while providing the lowest resistance to ground. Threads are rolled by roll threading process, which ensures that an even copper covering is maintained, even at the root of the thread, Roll thread gives greater strength than cut thread. Thread rolling process raises the surface of the rod, so that Thread dia is greater than Shank dia.
