Wallis copperbond earth rods offer installers the most economical method of achieving a low earth resistance.
Each rod has a high tensile strength, low carbon steel core. 99.95% pure copper is applied electrolytically and forms a metallurgical bond between the steel core and the copper. This combination makes the rod ideal for deep driving whilst also provides 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 0.25mm. Greater copper thicknesses are also available. Please contact our sales office for further information.
