The rods are manufactured from low carbon, high tensile steel with a 99.9 % pure electrolytic copper thickness of 250 microns. Thread rolling after plating preserves the copper thickness ensuring corrosion resistance across the threads. Threads comply with ANSIASME B1.1-2003. Extensible earth rods are coupled using threaded, easy to use brass alloy couplings. Connections can be made by using bolted clamps or exothermic welding process.
