Galvanize coated steel grounding electrode (line) is a new grounding products. It use special steels and special zinc as the main materials, double metal composite materials are formed by a special process. This product have high strength and high stability, but also has a cathode protection function, the contact resistance is less than 0.5, and the ratio of grounding and cathode protection to do more scientific, economic, service life is longer, life in general more than 50 years. Galvanize cladding steel grounding electrode can be used for grounding and cathode protection of the common occasions, also can be used as grounding products and cathode protection products.
