| "BIAX" COPPER BONDED EARTH ROD & ACCESSORIES " BIAX" COPPER BONDED EARTH RODS are manufactured from 99.9% 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 cannot be separated from the steel. The core is of low carbon steel of grade 080A20 of BS 970 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. ORDERING INFORMATION |
