PolyCarbon Storage Tanks


National Storage Tank is proud to be the exclusive purveyors of the newest advancement in caustic tank containment – PolyCarbon Tanks. A PolyCarbon Tank combined the strength of a Carbon Steel Tank on the outside with a Non-Corrosive Polyethylene lining on the entire interior surface. PolyCarbon tanks are geared toward what is inside, especially in the case of corrosive substances such as Sulfuric Acid, Liquid Fertilizer, Hydrochloric Acid, Sodium Hydrochloride, Ferrics, Alums, Polymers, and more.

Industries such as chemical manufacturing, paper manufacturing, soap and detergent manufacturing, pharmaceutical and biopharmaceutical manufacturing, fertilizer manufacturing, forensic testing, semiconductors, flavor and fragrance, and academic research are all dependent upon volatile chemicals that need to be kept in a safe and contained state.

Interior of a PolyCarbon Tank

PolyCarbon Tanks are Carbon Steel Tanks with a Heat Bonded Polyethylene secondary wall. The two substances, the Steel and the Polyethylene are bonded together to form a doubly protective tank that is 60% less expensive than stainless steel and 20% less expensive than fiberglass. Available in sizes up to 30,000 gallons – PolyCarbon is the future of caustic liquid storage. Below are PDF’s detailing the Substance & Chemical Resistance Data, as well as a PolyCarbon Tank Overview.
