Traditionally, zinc bonded steel and copper are the two main grounding materials in lightning & grounding conductors. Copper has better conductivity and service life than zinc bonded steel while is more expensive than it. The copper bonded steel material has not only good conductivity as copper but also has good strength as steel. Moreover, it can greatly save the project cost. Copper bonded steel is produced in our factory by electroplating process according to GB/12970.2-2009 Flexible Copper Stranded Conductors for Electrical Purposes - Part 2: Flexible Copper Stranded Conductors.
