Baoding Changdi Electric Power Equipment Manufacturing Co., Ltd. is a professional manufacturer specializing in lightning protection and grounding materials for over 10 years. Our main products include Copper Clad Steel Ground Rods, Copper Clad Steel Round Bars, Copper Clad Steel Flat Bars, Exothermic Welding Materials, Grounding Accessories, Copper Busbars, and Earthing System Solutions. We operate with advanced production equipment and strict quality control systems, and our products are manufactured in compliance with international standards. ISO-certified production management ensures stable quality and reliable performance.
Our Copper Clad Steel Round Bar is manufactured using a continuous molecular bonding process, combining a low-carbon steel core with high-purity copper. The copper layer is uniformly bonded and available in various thicknesses according to customer requirements, providing excellent conductivity, strong tensile strength, and outstanding corrosion resistance.
Compared with traditional galvanized steel conductors, copper bonded steel round bars offer a longer service life, lower grounding resistance, and superior mechanical performance. They are widely used in power substations, telecommunications towers, railway systems, solar power projects, petrochemical facilities, and lightning protection grounding networks.
Customized sizes, copper thicknesses, and OEM services are available to meet different project requirements worldwide.
