United Truck & Equipment, Inc. is a manufacturer and leading nationwide supplier of mobile fluid spray systems for a wide range of applications. We build our tanks from the ground up, starting with A36 sheet steel (or 304 2B stainless if specified) with a minimum thickness of 3/16 (or 7-gauge if stainless). Depending on the customer spec, shells are rolled either to a modified ellipse or a modified trapezoid with a radius bottom, yielding the desired volume distribution and/or rear view visibility. All shell seams are welded 100% on both sides. UnitedBuilt Tanks are designed to properly distributes the forces of hauled water evenly throughout the vessel. Toward this, we install curved bulkheads, which match or exceed the shell thickness. All contact between heads and shell is welded 100% on both sides. To suppress fluid surge during stops and starts, according to capacity and dimension we baffle our tanks with the appropriate number of ported and curved lateral steel sheets. Intern
