Comparison Of Performance Parameters Of Copper-clad Grounding Rods Of Different Specifications

Common copper bonded steel products on the market exhibit different characteristics in terms of copper layer thickness, steel core material, and mechanical strength, which need to be understood and compared in conjunction with project requirements.

For copper bonded steel ground rod specifications, copper layer thickness is a crucial reference point. The market generally offers copper layer thicknesses of ≥0.25mm (10 mils), with other thicknesses such as 13 mils also available. This significantly impacts the corrosion resistance and service life of copper bonded steel rod.

The selection of materials and mechanical strength indicators for the steel core of copper clad ground rods, such as tensile strength ≥600N/mm², reflect the impact resistance and toughness of copper coated earthing rod when driven into the soil.
