Copper Bonded rod is a best economical solution without compromising quality, Made of low carbon Steel & are atomically coated with copper. Hot Coating Process, Steel provides high strength while copper good conductivity best resistance against corrosion, Due to good conductivity of copper bonded rods these dissipate all leak current to ground, Earth Enhancing Compound - SG GEM PLUS - is filled in the bored hole and become a reason in substantially reducing earth resistance.
