Copper-clad steel ground rod is a composite grounding electrode featuring a high-strength steel core coated with an electrolytic copper layer (purity ≥99.9%) via electroplating or continuous four-dimensional cladding.
Copper-clad steel ground rod is a composite grounding electrode featuring a high-strength steel core coated with an electrolytic copper layer (purity ≥99.9%) via electroplating or continuous four-dimensional cladding. With a minimum copper thickness of 0.254mm (10 mil), it complies with UL 467 and DL/T 1312 standards. It combines the mechanical strength of steel with copper’s excellent conductivity and corrosion resistance. The metallurgical bonding between copper and steel ensures superior anti-corrosion and tensile performance, offering a design life exceeding 40 years. Widely used in power pylons, substations, telecom bases, and petrochemical tank farms, it supports both exothermic welding and mechanical connections, serving as a highly efficient, long-life alternative to traditional galvanized steel grounding materials.
