Copper clad ground rods combine a low-carbon steel core (typically 0.15% carbon) with a metallurgically bonded layer of 99.9% electrolytic copper, applied through an electroplating process. The copper coating maintains a minimum thickness of 0.254 millimeters (10 mils), with heavier options such as 13 mils available in specific models. This construction merges copper’s superior electrical conductivity with steel’s high tensile strength, delivering corrosion resistance and durability in harsh soil conditions.
The metallurgical bond prevents the copper layer from peeling or cracking during installation or bending, allowing the rods to be driven to significant depths without compromising integrity. Advanced electroplating production lines ensure uniform coating quality, validated through rigorous testing including salt spray tests and analysis using atomic absorption spectrophotometers and universal testing machines.
Copper clad ground rods comply with Underwriters Laboratories (UL) 467, American National Standards Institute (ANSI)/National Electrical Manufacturers Association (NEMA) GR-1, Canadian Standards Association (CSA) certification, Rural Utilities Service (RUS) requirements, and National Electrical Code (NEC) provisions. The steel core meets American Society for Testing and Materials (ASTM)-A-1080 specifications, with tensile strengths ranging from 80,000 to 100,000 pounds per square inch (PSI).
Available in diameters of 1/2 inch, 5/8 inch, 3/4 inch, and 1 inch, with standard lengths including 6 feet, 8 feet, and 10 feet, these rods serve applications in communications, power distribution, lightning protection, cable television, telecommunications, and industrial, commercial, and residential construction. Configurations include pointed ends or threaded designs for continuous extension, with custom sizes available for specific project requirements.

Frequently Asked Questions (FAQS)
What are the common applications for copper clad ground rods?
Copper clad ground rods are commonly used in communications, power systems, building systems, military installations, railway systems, broadcasting, lightning protection, cable television, data & telecommunications, industrial & commercial buildings, and residential construction for AC and DC work, especially in harsh surface environments.
What makes copper clad ground rods corrosion resistant and what is their expected service life?
The rods feature a uniform copper layer of 0.254mm or more, metallurgically bonded to a steel core through an advanced electrolytic process. This prevents exposure of the steel to soil and moisture, ensuring excellent corrosion resistance. Accelerated corrosion experiments conducted by authority departments have proven a service life of more than 40 years in different soil types. RaxPower employs strict quality control, including advanced testing instruments and galvanization processes, to maintain product reliability in extreme conditions.
How is the copper layer bonded to the steel core?
The copper layer is metallurgically bonded to the steel core through an advanced electrolytic process, ensuring perfect and tough bonding that prevents peeling, cracking, or exposure of the steel, resulting in a uniform coating without cracks, holes, or cavities.
Which industry standards and certifications do your copper clad ground rods comply with?
Our products meet or exceed key industry standards including UL-467, NEMA GR-1, CSA, ANSI C33.8, and Rural Utilities Service (RUS) requirements.
