99.9% cure Copper electrolytically bonded to low carbon steel cores.
Externally threaded/Unthreaded Copper Bonded Earth Rods are manufactured from a high tensile strength low carbon steel core with pure electrolytic copper molecularly bonded to its surface for a thickness upto 254 micron.
Driving Studs are used as impact bearing head when deep driving of earth electrode is required.
Couplers are used to combine two/more earth rods.
