Copper bond earthing rods offer installers the most economical method of achieving a low earthing 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. The combination makes the rod ideal for deep driving whist 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.
