Our custom mobile tanks are designed to take full advantage of every cubic inch of space and floor plan. Angles, radii, cut-outs, and notches are never a problem. Made to be moveable, our mobile tanks can serve as water holding tanks, fuel tanks, waste tanks, and even chemical or fertilizer tanks.
These custom fabricated tanks start at $1,491.

For businesses tackling a fluctuating demand for their products, mobile tanks offer a critical asset in maintaining a lean and responsive operation. When a machine needs a different material, or when a new configuration is necessary for a shift in production, having mobile plastic tanks at the ready ensures that the process doesn’t stutter.

Plastic Machining Capabilities & Benefits
We make connectivity to your vehicle flexible by machining threads directly into tank walls for low profile plumbing installations.
We can also provide welded-on threaded fittings or barbed connectors.
Reduced Sloshing & Complete Emptying
Unlike a molded tank, we can install internal supports and baffles to strengthen the welded holding tank and reduce sloshing.
We can also install castellated pick-ups and truncated baffles to allow complete emptying.
Greater Protection
Welded plastic holding tanks are far superior to molded holding tanks due to consistent wall thickness and overall heavier construction, which makes road hazard penetration less likely.

The Kinds of Mobile Plastic Tanks We Can Fabricate to Your Exact Specifications Include:
Machining Plastics vs. Molding Plastics
We cut all custom plastic holding tank components with the latest in CNC equipment, and use only Virgin U.S. material to ensure the absolute highest quality.
This accuracy and quality is repeated on every plastic holding tank for consistent operation and reliable function.
Highest Standards
It’s important to note that we weld our mobile plastic tanks to the strict German DVS welding standards.
This specification is used to measure the integrity of commercial chemical and acid tanks, so you can be assured of long-lasting integrity for this critical component.
