There are two kinds of MMO mesh anodes. One is designed especially for Cathodic protection systems in reinforced concrete structures. Another is designed for underground steel structures. The anodes will be packed in canister filled with calcined petroleum coke backfill. The substrate is expanded titanium grid. And the catalyst is Mixed Metal Oxide. Titanium expanded grid substrate coated with lrO2/Ta2O5 and meet ASTM standard B265 grade 1 or grade 2.
