ABSTRACT OF THE DISCLOSURE An expanded mesh strip of coated valve metal useful for fabricating anode grids for cathodic protection of steel reinforced concrete, tank bottoms, and the like, includes a smooth or uncut lateral edge and is relatively stiff to be packaged and shipped flat for fabrication into such cathodic protection anodes. The strip includes one or more longitudinally extending unexpanded sections to facilitate the tack welding of juxtaposed overlying strips to each other or such strips to conductor ribbons or bars. Several forms of strips are disclosed having various relationships of the expanded and unexpanded sections. The strip and anode formed thereby may be supported in elevated position on a bridge deck to avoid shorting contact with any exposed steel. The strip is easier to fabricate into a precision grid anode and better able to withstand the abuse of a heavy construction site.
