Why use zinc ribbon?
Zinc ribbon anodes provide a simple, cost effective, low maintenance method of corrosion control. These attributes makes zinc ribbon anode especially useful for unattended applications where other cathodic protection systems would require unsustainable monitoring or frequent maintenance.
Zinc ribbon anodes can also be used in fresh water, seawater environments.
They are commonly used in underground structures, coated steel pipelines with low current requirements and above ground storage tanks.
