COPPER BONDED EARTH RODS / GROUND RODS “KOOK” Copper Bonded Earth Rods / Ground Rods are manufacturedin the company’s OUR BRAND plant dedicated to the manufacturing of earthling rods. The plant is equipped with facilities to produce in house.. The steel core used for the manufacturing of the Copper Bonded Earth Rods is high tensile strength. The rods are electroplated with indigenously developed baths to produce a very strong bonding between the steel and copper. Also the innovative plating methods allow us to maintain copper plating of minimum 254 microns at any point of the rod. The extra edge of the quality of our Copper Bonded Earth Rods is also proved by the fact that all our threaded rods are threaded by thread rollingafter the copper plating process hence providing the accurate threading size.
