Copper Bonded Grounding Rod / earth rod
“Malvin Groups” copper bonded earth rod are made from low carbon Steel. Earth Rods are molecularly bonded with 99.9% pure electrolytic copper.
Salient Features-
- 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 roof of the thread. Roll thread gives greater strength than cut thread.
- Thread rolling process raises the surface of the rod, so that thread dia (T) is greater than shank dia. (S). As seen in figure: -

MECHANICALLY COPPER CLADED GROUNDING ROD
Mechanically copper claded grounding rod is made when electrolytic grade 99.9% copper tube with wall thickness of 0.25 (250 microns) is claded to a low carbon steel rod. Even if the rod is bent by 450, the copper tube should not peel out of the Steel rod.
