General Information

HASSCO’s double-wall tanks are an industry-proven, cost-effective way to store various fresh fuels. Best suited for farm and construction applications, these tanks come with four threaded openings, a fill cap, emergency/normal venting and a lockable spill-box incorporated into the design of the tank. Our double-wall tanks come standard with a 340-degree wrap and continually monitored by a vacuum gauge installed in the tank. All HASSCO tanks are phosphate washed before applying a high build metal treatment and two topcoats of enviro-smart water-based paint. Powder coatings available.
