Citizen metalloys provides copper bonded earth rods. These copper bonded earth rods are made up of 99.9 per cent pure electrolytic copper molecularly bonded onto a steel core in accordance with national and international standards. There is no metal interface, so dissimilar metal reaction cannot occur and the copper get separated from the steel. The core is of low carbon steel of grade 080a20 of bs970 and has high tensile strength of 600 n/mm². The copper covering is maintained at the root of the thread as; the threads are rolled onto the rod which ensures that an even copper covering is maintained. Rolled threads also give strength greater than cut threads.
