zinc ribbon anodes provide a very simple, cost effective, maintenance free method of corrosion control for buried or immersed metals such as iron, steel, aluminum copper, etc. Zinc is especially useful for unattended applications; those where other cathodic protection systems requiring monitoring and frequent maintenance or an external power source are not possible.

RotoMetals zinc ribbon anodes are used in a variety of applications: for cathodic protection on buried pipelines, for A.C. mitigation on pipelines, for sacrificial cathodic protection of secondary bottoms on above-ground storage tanks, for A.C. mitigation grounding mats, and for many other corrosion protection applications.




  • External areas of steel pipe, especially in difficult environments such as below grade in rocky and mountainous terrain, thawed zones in permafrost.
  • Interior bottom areas of oil storage tanks where salt water settles out.
  • Exterior bottom of oil storage tanks.
  • Interstitial spaces between old, corroded and new storage tank bottoms.
  • In the limited space between inner and outer casings of wells of various kinds.
  • For grounding steel tower footings of overhead power systems.
  • To provide cathodic protection as well as to dissipate induced AC current on coated steel pipe.
  • For personal safety as well as corrosion protection. To ground valves and test stations of pipelines which are subject to induced AC current and fault currents.

  • High Current output to volume ratio.
  • Easily conforms to any cathode length or configuration.
  • No special equipment is needed for installation.
  • Will not cause or magnify stray currents.
  • Generally used in soils of 2000 ohm-cm or less with prepared gypsum-clay backfill. However, this can be used in soils with higher resistivity on well coated pipelines with low current requirements.
  • Because this is in a continuous ribbon form, there is an even distribution of current density to the cathode.
