DAR Copper Coated Earth Rod offer installers the most economical method of achieving a low earth resistance. Each rod has a high tensile strength, low carbon steel core. 99.99% pure copper is applied electrolytically and forms a metallurgical bond between the steel core and the copper.
Copper Coated Earth Rod
This combination makes the rod ideal for deep driving while also providing lasting resistance to corrosion. The threads are formed by a cold rolling process which ensures strength and maintains the molecularly bonded copper covering along the full length of the threads. Cold-rolled threads are stronger than cut-threads. The standard copper thickness is 0.254 mm, but greater copper thicknesses are also available. The material used is pure copper molecularly bonded onto a steel .core
