For road lighting poles, safety fence posts, bicycle parking shelter posts, etc.! Prevent corrosion of the steel post foundation (ground level) using 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 corrosion protection and cathodic protection functions. During dry conditions, it prevents corrosion caused by micro cells through its coating corrosion protection function, and when in a wet state, it supplies cathodic protection current to prevent the formation of macro cells, thereby protecting the steel material with dual corrosion prevention functions. 【Installation Examples】 ■ Road lighting pole (150φ) ■ Road lighting pole (216φ) ■ Fence post ■ Safety fence post ■ Bicycle parking roof post ■ Apartment balcony post ■ Pier safety fence post ■ Movable bridge safety fence post ■ Fall prevention fence post *For more details, please refer to the PDF document or feel free to contact us.
