The copper grounding rod is used in the lightning protection underground, which is made of high-quality steel core covered by 99.9% electrolytic copper molecules. The thickness of the surface copper plating layer is 0.25mm. The molecular bond with the steel core surface is formed by electroplating, which has high agglomeration properties (tightly bonded and has screw thread coils).

The steel core is a type of bar whose diameter is required to have a high tensile strength of up to 600N/mm2 so that the grounding rod can easily go deep into the ground on impact. It is guaranteed to be able to be used for at least fifty years.
