One of the most common methods of transporting bulk cargo is a cylindrical container known as a drum, also referred to as a barrel. These drums are used to transport thousands of different cargo including industrial chemicals, acids (and other corrosives), oils, solvents, paints, resins, adhesives and soaps. Painted steel drums and drums made from high-density polyethylene (HDPE), typically called poly, or plastic drums, are used most often to transport and store such cargo.
Trains and locomotive railcars operate in harsh environments which degrade the exterior paint and protective finish over time. For the interior of the tank and hopper cars, the linings must provide protection from highly corrosive cargo which can lead to heavy corrosion and premature coating failure. These vessels require durable and long-lasting finishes as varying weather and cargo can strip away these protective coatings.
