The electrodes have a covering of electrolytic copper with a width of 254μm and purity 99.9% which allows a proven resistance to corrosion. This type of electrolytic covering does not produce cracks or fissures, which are produced in the exterior layer of the copperclad rods, worsening its resistance to corrosion.
Using the adequate accessories, threaded Copperbond earth rods allow the extension of the rod to get better earthing resistances.
