Abstract
A flexible, nonstretchable, titanium, ladder anode for cathodic protection of steel reinforced concrete structures formed of multiple titanium strips including multiple electric current-carrying titanium strips. Ladder anodes of titanium without an electrocatalytically active metal coating can be used in a cathodic protection system operated at an anode current density up to about 20 milliamps per square foot. Ladder anodes of titanium having an electrocatalytically active metal coating are additionally useful at higher anode current densities. The ladder anodes form at the intersections of the strips less than 200 nodes per square meter and have a surface area of about 500 to about 900 square inches per pound.
