Single copper-coated steel round steel is a new type of grounding electrode manufactured using electroplating, continuous casting, and other advanced processes. It covers a 99.9% pure copper surface onto a specially designed steel core, offering the same conductivity as a copper rod of the same diameter, but at a significantly lower cost. It also boasts superior corrosion resistance compared to galvanized steel, and features excellent conductivity, low resistance, superior corrosion resistance, easy transportation, convenient installation, and high installation efficiency. It is an ideal choice as a substitute for traditional grounding materials such as round steel, angle steel, and galvanized flat steel.
