Millinocket Fabrication and Machine’s custom double wall tanks are precision-machined and highly-engineered storage tanks that are capable of above-ground or below-ground storage. These double wall steel tanks are manufactured from high-grade steel where the main tank is surrounded by an outer steel wall that provides critical protection against spills or leaks. As a double wall tank manufacturer, we ensure that the insides of both walls are coated with an anti-corrosive zinc coating so that steel degradation due to corrosive chemicals is never a concern.
