The Electrochemical Cathodic Protection System is an active corrosion protection solution designed for steel structures and metal foundations. It operates by continuously delivering low-voltage protective current through an intelligent control unit, forming a stable electrochemical protection circuit with buried anodes and anode patches. This ensures that metal structures remain in a cathodic state, effectively preventing corrosion and extending service life.
The Electrochemical Corrosion Protection System continuously delivers low-voltage protective current through an intelligent controller, creating a stable electrochemical protection field using buried anodes and anode patches.
After installation, the buried anodes transfer protective current through the surrounding soil to steel foundations, ground screw systems, and other metal structures. This protective current helps suppress corrosion and extend the service life of the structure.
For exposed metal areas, structural connections, or isolated conductive sections, anode patches can be installed to provide supplementary protection and eliminate potential protection gaps.

1. How does this system work?
The system works by using an intelligent control unit to output a low-voltage DC current. Through buried anodes and anode patches, it forms an electrochemical protection circuit, keeping steel structures and foundation metals continuously protected and significantly slowing down corrosion.
2. What is the function of the anode patch?
The anode patch is used to supplement localized protection current. It solves the issue of uneven current distribution at metal joints or isolated areas, eliminating protection blind spots and ensuring more uniform corrosion protection across the entire structure.
3. What is the function of the buried anode?
The buried anode releases protective current into the soil, providing long-term and stable corrosion protection for underground steel structures, ground anchors, and buried metal components.
4. Does the system require maintenance?
The system operates stably and mainly relies on the control unit for automatic regulation. Only periodic checks of current output status and connection conditions are required, resulting in low maintenance costs.
5. What types of buildings is it suitable for?
It is suitable for modular houses, light steel structures, ground screw foundation systems, container houses, and various underground metal structure corrosion protection applications.
