- Why material selection determines whether your tank holds up in the field, not just on the data sheet.
- How Robomold® robotic rotational molding delivers tighter tolerances, dual-layer parts, and integrated features, including baffles, cupholders, and mounting points, that conventional tooling can't produce in one piece.
- Why one-piece, weld-free construction removes the leak points and extra machining steps that make metal tanks heavier and more expensive to produce.
- Made in USAISO 9001:2015 certified. Engineered and built in Cannon Falls, Minnesota, with in-house tooling that keeps design changes on your timeline, not an incumbent supplier's.
Why It Matters: Rotomolded vs. Metal Tanks
Rotationally Molded Tanks Are Outperforming Metal on Weight, Cost, and Reliability
One-piece, weld-free construction means fewer potential leak points and no rust or corrosion to manage over the life of the tank. Complex geometries (integrated baffles, mounting points, storage compartments) come standard, without the extra machining steps a metal tank requires. The result is a lighter, more affordable part that holds up as well or better in the field.
