Introduction
DAR Copper Coated Earth Rods offer installers the most economical method of achieving a low earth resistance.
Each rod features a high tensile, low-carbon steel core that is electrolytically bonded with 99.99% pure copper, creating a strong metallurgical bond between the steel core and the copper coating. This construction provides excellent mechanical strength for deep driving while delivering long-lasting corrosion resistance.
Copper Coated Earth Rod
The cold rolling process used to form the threads ensures exceptional strength while maintaining the molecularly bonded copper layer throughout the full thread length. Compared to cut threads, cold-rolled threads provide superior durability and reliability.
The standard copper coating thickness is 0.254 mm, with thicker coatings available for specific project requirements. The rod is manufactured from a steel core molecularly bonded with pure copper, making it suitable for demanding grounding applications. All threads comply with the Unified National Coarse (UNC-2A) standard.
