Single copper-coated steel round bars are a new type of grounding electrode made using electroplating, continuous casting, and other processes. They are manufactured using advanced technology to cover the surface of a special steel core with 99.9% pure copper, providing conductivity equivalent to that of copper bars of the same diameter. However, they are significantly more cost-effective than pure copper and offer superior corrosion resistance compared to galvanized steel. They possess numerous advantages, including excellent conductivity, low resistance, superior corrosion resistance, easy transportation, convenient installation, and high installation efficiency, making them an ideal alternative to traditional grounding materials such as round bars, angle bars, and galvanized flat steel.
