How It Works
-
Low Resistance Path – The pure copper outer layer (C10200/C11000) provides excellent conductivity, allowing current to flow rapidly from the equipment into the rod.
-
Mechanical Strength – The steel core (though not explicitly listed, standard for copper clad steel) provides high tensile strength for driving deep into soil without bending.
-
Corrosion Protection – The copper coating resists oxidation and galvanic corrosion, ensuring decades of stable ground resistance.
-
Current Dissipation – When installed vertically or horizontally in contact with soil, the rod spreads fault current over a large earth volume, reducing step and touch potentials.
-
Electromagnetic Interference (EMI) Shielding – The conductive copper surface helps divert stray electromagnetic fields away from sensitive electronics.
Packing and Shipping
All copper pipes are packaged in export-standard wooden bundles or boxes, designed to protect the material during transit and suitable for various modes of transportation.
Frequently Asked Questions
1. Is this product UL certified?
Yes. Our copper bonded earth rods carry UL certification for earthing and grounding applications, meeting strict safety standards.
2. What diameters and lengths are available?
We offer diameters from 1mm to 200mm and lengths from 1m to 6m. Custom specifications are available upon request.
3. What is the typical delivery time?
For stock items: 1 day. For custom orders: within 7–15 working days depending on quantity.
4. Which international standards do you comply with?
Our rods comply with ASTM, AISI, EN, BS, JIS, GB/T, BSI, AS/NZS, and ISO.
5. Can I use this rod in marine or chemical environments?
Yes. The pure copper outer layer and optional polished/bright finishes provide excellent corrosion resistance, making it suitable for marine and chemical plants.
6. What is the difference between a copper bonded rod and a solid copper rod?
Copper bonded rods have a steel core (high strength, lower cost) with a copper cladding (good conductivity). Solid copper rods are more expensive and softer, making them harder to drive deep. Our bonded rod is ideal for deep driving.
7. How do I place an order?
Contact us with your required diameter, length, quantity, and destination port. We accept T/T, L/C, and West Union under FOB, CFR, or CIF terms.
8. Do you ship globally?
Yes. We export regularly to the USA, Canada, Japan, UK, Saudi Arabia, India, Singapore, South Korea, Australia, Brazil, Argentina, Mexico, Russia, Turkey, Greece, France, Germany, and Spain.
9. What packaging do you use?
Standard sea-worthy package: rods fixed with belts inside fumigated wooden boxes to prevent corrosion and damage during transit.
10. What is the tensile strength of the copper layer?
The copper cladding has a tensile strength (Ts) of 22–25 MPa, while the underlying steel core provides much higher overall rod strength for driving.
