Single copper-coated steel round bars are a new type of grounding material made using electroplating, continuous casting, and other advanced processes. They feature a 99.9% pure copper coating applied to the surface of a specially designed steel core, providing electrical conductivity comparable to that of a solid copper bar of the same diameter. Yet, they are significantly more cost-effective and offer superior corrosion resistance compared to galvanized steel. These bars boast numerous advantages such as excellent conductivity, low resistance, superior corrosion resistance, easy transportation, convenient installation, and high installation efficiency, making them an ideal replacement for traditional grounding materials like round bars, angle bars, and galvanized flat steel.
