Key Features & Technical Specifications
High Conductivity: Made from 99.9% pure copper, achieving ≥98% IACS conductivity, ensuring minimal resistance for efficient fault current dissipation.
Anti-Corrosion Design: The natural copper oxide layer provides inherent resistance to atmospheric corrosion. Optional tin or nickel plating is available for extreme environments.
Robust Mechanical Strength: Each rod is cold-drawn and annealed to prevent brittleness, with a tensile strength of ≥200 MPa for easy driving into various soil types.
Precision Threading: Available with UNC or UNF threads (customizable) for secure coupling and extension.
Versatile Dimensions: Standard diameters from 14 mm to 20 mm and lengths from 1.5 m to 3 m. Custom sizes are offered upon request.
Easy Installation: Chamfered tip for smooth penetration, compatible with standard driving tools and coupling connectors.
Eco-Friendly: 100% recyclable pure copper material, complying with global environmental regulations.

Frequently Asked Questions
Q: What is the difference between pure copper and copper-clad steel ground rods?
A: Pure copper rods offer higher conductivity (≥98% IACS) and better corrosion resistance, but are more expensive. Copper-clad steel rods are more economical but have lower conductivity and may corrode if the copper layer is damaged. Our pure copper rod is ideal for critical grounding applications where long-term reliability is paramount.Q: Can I order rods with a length longer than 3 meters?
A: Yes, we can customize lengths up to 6 meters, and longer rods can be coupled using threaded connectors. Please contact us with your specific requirements.Q: Do you provide surface treatment to improve corrosion resistance?
A: The natural copper oxide already provides excellent corrosion resistance. For extremely corrosive environments (e.g., coastal or chemical plants), we offer optional tin or nickel plating. This is available upon request.Q: What certifications do your products have?
A: Our manufacturing facility is ISO9001 certified, ensuring consistent quality. We can also provide test reports for conductivity, tensile strength, and dimensional accuracy upon request. Specific product certifications (e.g., UL) can be arranged for large orders.Q: How are the rods packed for export?
A: Each rod is individually wrapped with plastic caps on both ends to protect threads. Bundles are strapped and shrink-wrapped, then packed in wooden crates or pallets according to your shipping requirements. We ship from Tianjin, Shanghai, Qingdao, or Ningbo ports.Q: What is the minimum order quantity (MOQ)?
A: The MOQ for standard sizes is 500 pieces. For custom sizes or special finishes, the MOQ may be higher. Please contact us for details.Q: How long does production and delivery take?
A: For standard rods, production takes 10–15 working days. Shipping time depends on the destination port. We can provide a detailed lead time upon order confirmation.Q: Can I get a sample before placing a bulk order?
A: Yes, we offer samples for evaluation. The sample cost and shipping are usually at the buyer's expense, but we can deduct the sample cost from the first bulk order. Please contact our sales team to arrange.
