Wuxi Yansheng Technology Co., Ltd., a professional manufacturer established in 2017 with a factory size of 1,000-3,000 square meters and an annual export value between US$50 million and US$100 million, proudly presents our Double Threaded Copper Bonded Steel Earth Rod for lightning protection grounding. With over 100 employees and a strong commitment to quality, we have supplied reliable grounding solutions to markets across North America, South America, Europe, Asia, Africa, and Oceania. This earth rod combines the high conductivity of copper with the strength of steel, featuring double-threaded ends for easy connection and extension, making it an ideal choice for lightning protection and grounding systems in various applications.
Our copper bonded steel earth rod is manufactured using a molecular bonding process that ensures a uniform, continuous copper layer firmly bonded to the steel core. This construction provides excellent corrosion resistance, high tensile strength, and superior electrical conductivity. The double-threaded design allows for quick and secure coupling with other rods or connectors, simplifying installation and reducing overall project time. Whether used in residential, commercial, industrial, or utility grounding systems, this rod delivers consistent performance and long service life.
Key Features & Benefits
High Conductivity: The copper layer ensures low electrical resistance for efficient grounding.
Corrosion Resistance: Molecular bonding prevents copper peeling, even in harsh soil conditions.
Strong Steel Core: Provides mechanical strength to withstand driving and environmental stress.
Double Threaded Ends: Enables easy extension with coupling nuts or connection to grounding wires.
Customizable Lengths & Diameters: Available in various sizes to meet specific project requirements.
Compliant with International Standards: Manufactured under strict quality control (ISO9001, ISO14000, etc.).
Cost-Effective: Combines performance of solid copper rod with lower material cost.
Technical Specifications (Typical)
| Parameter | Value |
| Copper Thickness | ≥0.25 mm (customizable) |
| Steel Core Material | Low carbon steel (high tensile) |
| Tensile Strength | ≥600 N/mm² |
| Electrical Conductivity | ≥20% IACS (copper layer) |
| Thread Type | M10, M12, M16, or custom |
| Available Lengths | 1.5 m, 2 m, 3 m, etc. |
| Standard Compliance | IEC, BS, UL (optional upon request) |
The double threaded design eliminates the need for welding or special tools, allowing rapid assembly of multi-rod grounding systems. This is particularly beneficial for deep grounding installations where multiple rods must be coupled to achieve low resistance. Each rod is supplied with a coupling nut and a driving cap (optional) to protect the threaded end during installation. Our earth rods are also available with a copper-plated steel driving stud for added convenience.
Application Areas
Lightning Protection Systems: For buildings, towers, and open structures.
Power Substations & Transformers: Reliable grounding for equipment.
Telecommunication Towers: Ensures safety and signal integrity.
Industrial Plants: Grounding of machinery and electrical panels.
Residential & Commercial Buildings: Foundation and earthing systems.

Frequently Asked Questions
Q: What is the difference between a copper bonded steel rod and a solid copper rod?
A: Copper bonded steel rods have a steel core with a copper layer, offering similar conductivity at a lower cost and higher mechanical strength. They are more economical for deep grounding and are resistant to bending during driving.Q: How do I connect multiple rods together?
A: The double threaded ends allow you to use coupling nuts to join rods end-to-end. Simply screw the threaded end of one rod into the coupling nut on another rod. No welding or special tools are required.Q: What is the typical copper thickness?
A: Standard copper thickness is ≥0.25 mm, but we can customize it based on your soil corrosivity and project requirements. Thicker layers are available for extremely corrosive environments.Q: Can these rods be used in rocky soil?
A: Yes, the steel core provides high tensile strength (≥600 N/mm²) to withstand driving through hard soils. We recommend using a driving cap to protect the threaded end during installation.Q: Do you provide test certificates or compliance reports?
A: Yes, we can provide material test reports, copper thickness verification, and tensile strength tests upon request. Our quality management system is certified to ISO9001, ISO14000, and other standards.Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is typically 100 pieces. For custom specifications, please contact our sales team for MOQ details.Q: How are the rods packaged for export?
A: Rods are bundled with steel straps, then wrapped in waterproof plastic and packed in wooden crates or pallets, depending on the quantity and shipping method. We ensure safe transport to any port.Q: Can I get a sample before placing a bulk order?
A: Yes, we offer samples (1-2 pieces) for evaluation. Freight cost is negotiable, and sample fee is refundable upon bulk order.
