Corrosion protection: tank shell
Balmoral’s cylindrical tank shell design is manufactured using pre-mill galvanized steel, with 305g/m² of zinc coating each side. On occasion, where heavier designs are required, the sheets will be hot dipped galvanized with more than 610g/m² zinc coating on either side. For specialised applications aluminium and stainless steel tank options are available.
All Balmoral tank fittings, flanges and accessories are also hot dipped galvanized as standard with options of epoxy or polyester coatings available. The galvanized coating of the tank shell along with the options of an epoxy performance coating for such applications as potable water or polyester coatings for aesthetic requirements guarantee long durability, low maintenance and extended life-cycle costs of the tank shell. Colour options for the epoxy or polyester coatings are available if required.
On standard galvanized tank designs, the coating of the tank shell doesn’t mean a reduction of the galvanized zinc coatings, the epoxy and polyester coatings are in addition to the galvanizing process.
Corrosion protection: tank components
Under the (LPCB) LPS 1276 approved design, galvanized roof purlins are kept out of the stored water thus extending the life of the tanks roof cover. All nuts, bolts and washers are spun galvanized coated, structural components such as top and bottom angles, wind stiffeners and access manways are hot dipped galvanized with in excess of 610g/m² of zinc coating.
