Copper bonded earthing rod 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-driven 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 ***** junctions. These rods, which come in threaded and unthreaded varieties and are suitable for exothermic welding and brass-alloy *****s, are designed to satisfy BS 4360 grade 43A and are appropriate for use in commercial, industrial, and residential settings.
