CST’s Aquastore™ tanks are available in diameters from 11 feet (3.3 m) to 204 feet (62.2 m) and capacity from 20,000 gallons (75 m3) to over 6 million gallons (22,700 m3). The factory-applied silica glass coating on Aquastore tanks forms a hard, inert barrier for both the interior and exterior of surfaces of the tank. It protects the steel core against weather and corrosion. The tank’s proprietary Edgecoat™ process produces a barrier coating on the sheet edges so that the entire steel panel is encapsulated in a glass shell. The physical properties of Aquastore tanks’ glass coating are especially suited to municipal/industrial liquid storage applications.
