Ground rod and Accessories
Copper bonded ground rod is cast through an electrolytic process, to 99.9% copper molecules evenly covering the steel core. It is very uniform copper layer and the thickness of 0.254mm or more. Products have conductive properties of copper and the tensile strength of steel. Since the copper layer and the steel material is a binding molecule, the copper layer is not easily peeled off, and will not crack when bent in operation.
