Molded - Vertical

Designed for either indoor or outdoor use, vertical bulk storage tanks have a flat bottom for easier installation. They are engineered for tough applications and provide excellent low-temperature impact resistance. These plastic molded tanks are lighter in weight, more corrosion-resistant and easier to maintain than steel tanks. Seamless construction eliminates leakage problems often associated with fabricated tanks and unlike fiberglass, plastic tanks do not wick.
