  • Insulative/low moisture absorption
  • Easy to repair


We’re well known for our custom tanks. Boat tanks are often bizarre shapes and sizes, so many of our clients send us their old tanks—which we copy exactly. We build tanks for sewage and water treatment plants, paper mills, and much more. These larger tanks are made to order. They’re built in sections and assembled on site. All of our tanks are baffled at a maximum of 16″ on center, and we drill and tap all the ports to the customers’ specifications. Everything we fabricate is tailored to meet our client’s needs, and we work off designs or prototypes that are supplied to us. Triple M Tanks Feature:

  • Triple M’s Stress Tempering Technology
  • Reinforced ports, drilled and tapped
  • Inspection plates/cleanouts/draw tubes
  • Meets USCG minimum pressure tests
  • Standard Lifetime Warranty


Specialized Polypropylene Tanks — Polypropylene is used to make water, holding, diesel fuel and other tanks. Polypropylene is FDA approved for the food industry and does not give off the distinctive plastic flavor of polyethylene. It is more rigid than polyethylene, and will withstand higher temperatures. All our tanks are nitrogen welded inside and out, and this ensures that the weld will last forever. We back every item we make by a lifetime warranty, because we know the quality of our custom built products. Specialized PVC Tanks — We fabricate gasoline tanks out of PVC.
