COPPER BONDED EARTH RODS: The Ultimate Foundation for Reliable Earthing & Grounding Systems
Overview
Our Copper Bonded Earth Rods are critical components for establishing a safe, effective, and long-lasting earthing and grounding system. Designed to provide a low-resistance path to the earth for fault currents, lightning strikes, and static electricity, these rods combine the superior conductivity and corrosion resistance of copper with the high tensile strength and cost-effectiveness of steel.
Each rod features a high-grade, low-carbon steel core that is molecularly bonded with a minimum of 99.9% pure electrolytic copper, ensuring an unbreakable, non-peeling bond that outperforms simple copper plating or cladding. This advanced manufacturing process results in a durable, high-performance electrode essential for the safety and functionality of electrical installations across all sectors.
Key Features & Benefits
Superior Corrosion Resistance: The thick, pure copper layer provides excellent protection against soil corrosion, ensuring a long operational life, even in aggressive ground conditions.
High Electrical Conductivity: The pure copper surface offers a consistently low resistance path to earth, crucial for dissipating fault currents and lightning energy effectively.
Exceptional Tensile Strength: The steel core allows the rod to be driven deep into the ground with minimal effort using power hammers, without bending, mushrooming, or suffering damage to the tip or threads.
Durable & Long-Lasting: With a molecularly bonded copper layer that will not crack, peel, or separate, our rods maintain their integrity and performance for decades, significantly reducing maintenance and replacement costs.
Cost-Effective Solution: Offers the performance characteristics of solid copper earth rods at a fraction of the cost, making it an economically viable choice for large-scale projects.
UL / IEC Compliant: Manufactured to meet and exceed international standards such as UL 467, IEC 62561-2, and BS 7430, guaranteeing reliability and safety.
Non-Peeling Bond: The unique molecular bonding process ensures the copper layer remains intact even under extreme stress during installation, maintaining optimal conductivity throughout its lifespan.
Superior Construction
Our Copper Bonded Earth Rods are meticulously engineered for peak performance:
High Tensile Steel Core: A precisely drawn, low-carbon steel core forms the robust backbone of the rod, providing the necessary strength to withstand the rigors of mechanical driving into various soil types.
99.9% Pure Electrolytic Copper: A meticulously controlled electrolytic process applies a uniform and dense layer of pure copper onto the steel core. This process creates a molecular bond at the interface, ensuring permanent adherence and preventing delamination.
Controlled Copper Layer Thickness: We offer rods with various copper layer thicknesses (e.g., 250 microns, 330 microns, 500 microns, or customized), allowing you to select the optimal corrosion protection for your specific environment and desired lifespan.
Rolled Threads: Where threaded rods are required, threads are precision-rolled onto the copper layer, preserving the integrity of the copper and maintaining its corrosion resistance, unlike cut threads which expose the steel core.
