For the protection of steel materials! Prevent corrosion of the steel column foundation (ground level) with the sacrificial anode function of zinc!
The "Pole Keeper" is a closed-circuit type of cathodic protection device that prevents corrosion by using zinc alloy anodes and flexible zinc anodes to inhibit the formation of macro cells. By installing a zinc alloy anode (metal guard ring) around the support and filling the inside with a flexible zinc anode (metal guard solid), it has a composite structure that combines coating protection and cathodic protection functions. During dry conditions, it prevents corrosion caused by micro cells through its coating protection function, and when in a wet state, it supplies cathodic protection current to prevent the formation of macro cells, thereby protecting the steel materials with dual corrosion prevention functions. 【Features】 ■ Uses zinc alloy anodes and flexible zinc anodes ■ Prevents corrosion from micro cells during dry conditions with coating protection function ■ Supplies cathodic protection current in wet conditions to prevent the formation of macro cells ■ Protects steel materials with dual corrosion prevention functions *For more details, please refer to the PDF document or feel free to contact us.
