How is a copper bonded earthing rod manufactured?
A copper bonded earthing rod is produced through a careful and controlled process that guarantees its excellent conductivity, sturdy mechanical performance, and extended service life. The procedure starts with a core made of high-tensile, low-carbon steel, giving the rod great strength and making it possible to put it very deeply into the ground without bending or breaking. The steel core is meticulously cleaned and treated to be able to bond properly with copper.

The following step is to do molecular or electrolytic bonding, where a thick layer of pure copper is permanently attached to the steel core. This is not a simple plating; the copper layer is joined to the steel at a molecular level, which guarantees that it won't peel, crack, or separate during installation or over time. The thickness of the copper coating is strictly controlled to conform to industry standards and to give corrosion resistance in different soil conditions.

The rods are straightened, cut to required lengths, and threaded or chamfered at the ends to make installation easier and coupling afterwards. Quality checks are done to confirm copper thickness, adhesion strength, and surface finish.

The earthing rod is connected to the grounding conductor with the help of professionals' connectors like COPPER LUGS during installation, thus ensuring a low-resistance joint. A manufacturer like PIONEER POWER INTERNATIONAL and others implement quality control measures that are very rigid in order to sell durable copper bonded earthing rods that are safe and perform well electrically for a long time.
