Copper bonded earthing rods from Pioneer Power International have a 99.9 percent pure electrolytic copper layer molecularly attached to a high-tensile, low-carbon steel core. This hybrid design combines copper's superior electrical conductivity and corrosion resistance with steel's mechanical strength, which enables deep installation either power driving or manual. Benzotriazole derivatives are applied to the copper surface to prevent oxidation and increase durability. In order to ensure optimal current dissipation throughout the system, threads are roll-formed to preserve continuity of copper coverage even across coupling junctions. These rods, which come in threaded and unthreaded varieties and are suitable for exothermic welding and brass-alloy couplings, are designed to satisfy BS 4360 grade 43A and are appropriate for use in commercial, industrial, and residential settings.
