What is a copper-plated ground rod？
Copper-plated steel grounding rods, also known as copper-plated grounding rods or copper-clad steel grounding rods, refer to a grounding electrode made by covering a steel rod with copper through methods such as electroplating or continuous casting, achieving a high degree of combination between copper and steel. According to the type of use, they can be divided into combined-type grounding rods or single-rod-type grounding rods. Combined-type grounding rods consist of a copper-plated grounding rod with threaded ends, a pointed tip, impact-resistant bolts, and connectors, and their advantages include convenient transportation, and they can be made into longer lengths according to construction needs. Single-rod-type grounding rods consist of a single copper-plated grounding electrode, which is convenient for construction.
The copper-plated grounding rod saves copper material and reduces costs, while maintaining the same electrical conductivity and incorporating the hardness of copper. Copper-plated grounding rods are mainly used in lightning protection grounding, which can reduce resistance values. When the lightning rod on the top of a building is struck by lightning, the current can be quickly discharged, achieving the effect of lightning protection.

Characteristics and technical advantages of copper-plated grounding rods:
1. Unique Manufacturing Process: The cold rolling and hot drawing production process is adopted to achieve a metallurgical bonding between copper and steel. It can be drawn like a single metal without delamination, warping, or cracking.
2. Superior Corrosion Resistance: The composite interface is high-temperature melted with no residue, preventing corrosion phenomena at the junction; the surface copper layer is relatively thick (with an average thickness greater than 0.254mm), which is highly resistant to corrosion, extends the service life (greater than 30 years), and reduces the intensity of maintenance work.
3. Better Electrical Performance: The outer layer of pure copper material has excellent electrical conductivity, resulting in a much lower inherent resistance value compared to conventional materials.
4. Widely Applicable and Safe: The product is suitable for grounding construction under different soil moisture, temperature, pH value, and resistivity conditions.
5. Easy and Fast Installation: With a complete set of accessories and convenient installation, using exothermic welding or special connecting hardware, the joints are solid and have good and stable electrical conductivity, which can effectively increase the construction speed.
6. Low Construction Cost: Compared to the traditional method of using pure copper grounding rods, the cost is significantly reduced.

Copper-plated Grounding Rods Technical Specifications:
1. Copper Layer Thickness: ≥0.25mm
2. Electrical Resistivity: ≤0.0592 mm²/μΩ·m
3. Tensile Strength: ≥500 N/mm²
4. Corrosion Resistance: After soaking in a 10% nitric acid solution for over 90 hours, the weight loss due to corrosion should not exceed 15%.
5. Copper Layer Adhesion: After continuous exposure at a body temperature of 300°C for over one hour followed by rapid cooling, the copper layer should not peel off.
6. Copper Layer Ductility: When the copper-plated grounding rod is bent 180°, the copper layer should show no cracks or signs of flaking.

Copper-plated Grounding Rods Product Application Range:
- The copper-plated grounding rods are used in lightning protection grounding projects for various locations such as petrochemical plants, oil storage depots, power plants, substations, communication base stations, airports, and network server rooms. The electroformed copper grounding rods, when buried deep underground, offer strong protection against both natural corrosion and electrochemical reactions. The grounding rods and grounding network wires are connected using a chemical welding agent, which places the grounding device entirely under the protection of copper, making it a truly maintenance-free grounding device.
- According to the grounding function, the copper-plated grounding rods can generally be divided into:
1. Working Ground - Ground rods connected to electronic equipment to achieve equipotential bonding, ensuring the normal operation of the equipment.
2. Lightning Protection Ground - Directing the powerful impulse currents in the atmosphere into the ground.
3. Protective Ground - Protecting people and animals from electric shock.
- Copper-plated grounding rods can be used in general environments as well as in special environments such as acidic mud, humidity, salinity, and areas with chemically corrosive media. They are mostly not treated for corrosion protection because the content of active ions in the soil is one of the factors affecting the grounding resistance. In many soils, the compounds containing active electrolytic ions are relatively scarce, and a simple grounding body alone would not meet the grounding requirements.
