German Engineered. American Made.

Manufactured in Europe for over 25 years, extrusion wound  tanks are made with polyethylene or polypropylene and provide the most flexible options for accessorizing.  This makes the tanks most useful for a wide variety of applications.

Perfect for Challenging Solutions

Our tanks are the perfect solution for storing even the strongest, hardest-to-contain chemical like sulfuric acid, hydrochloric acid, nitric acid and sodium hypochlorite.

Structurally Sound

Our tanks are the high performance alternative to Carbon Steel, Stainless Steel, Fiberglass and Rotationally Molded plastic tanks.

Longer Lasting

With wall thicknesses up to 6 inches thick, these sturdy tanks don’t bulge, buckle, oxidize, or corrode as other tanks can.

Virtually Maintenance Free

Because the tank color is an additive to the plastic itself, there is never a need to sand blast or repaint.

Customers turn to us when they are tired of other tanks that don’t meet their needs and fail due to bulging in thin-walled, roto-molded tanks.

Pipes & Ductwork

Our manufacturing capabilities also allow us to be a great supplier of thick-walled pipes.


Because of our unique manufacturing methodologies, we are able to offer a wider range of options than many other plastic tank manufacturers.  Click to learn more.
