The "Giù...stò" underground tank is coated with at least 500 micrometres of epoxy powder (up to 3000 l) to protect it from stray current and corrosion. Moreover, for additional protection, tanks comes with a cathodic protection kit (copper sulphate electrodes and magnesium anodes);

The epoxy powder coating features high chemical resistance against corrosion, scratches, and abrasions. It also has good mechanical resistance and low environmental impact;

The concrete base is part of the standard equipment supplied for tanks to 1750 l. For higher capacities, it is an optional;
