Abstract
A grid anode for cathodic protection of steel reinforced concrete structures formed of multiple valve metal strips including multiple electric current-carrying valve metal strips. Valve metal strip grid anodes without an electrocatalytic metal surface can be used in a cathodic protection system operated at an anode current density up to about 20 milliamps per square foot. Composite anodes having an electrocatalytic metal coating are useful at higher anode current densities.
