Superior was one of my better decisions

I can tell you that I was extremely happy with the professionalism of the entire process from design to install. Superior was one of my better decisions while running Saltwater Disposal of North Dakota

Fantastic Bolted Steel Tank!

“Absolutely fantastic tank!  Your crew was a very impressive team; the tank went up much quicker than we had expected.”

Ed C.

Superior Customer Service

“Superior Tank took care of us in our time of need and had the best price around. Mr. Huel took very good care of us from start to finish as did the crew putting the tank up. Superior Tank was also recommended to us by a neighboring water company who was very pleased with their work as well.  Thank you Superior Tank .”

Quinn A.

A Historic Moment

“Today  water began flowing to our customers. A bit of clean-up, replace the Brown’s gate, and we will be finished. One bit of history I remember tells me that this is the first project of this magnitude since the Empire State Building to finish ahead of schedule and (slightly) below budget. Thank you for your support.”

Peter S.

I only deal with Superior

“I DO NOT deal with any other bolted tank company, period. I deal only with Superior because of Huel, and he makes sure I get the best product that Superior has to offer and Huel stands behind what he puts his name on.”

Bolted Steel Tank Manufacturing


Superior Tank Company, Inc. engineers, manufactures and installs bolted steel tanks in a wide variety of configurations and sizes.  Our bolted steel tanks meet a number of industry standards including American Water Works Association (AWWA) D100-3, National Fire Prevention Association (NFPA), FM Approvals and American Petroleum Institute (API) 12B and can be used for a variety of applications including potable water storage, water storage for fire protection, wastewater storage and crude oil storage. To meet the needs of various customers, our bolted steel tank are available in a range of capacities from 4,000 gal. / 100 BBLs to 2,500,000 gallons / 60,000 BBLs.

All of our bolted steel tanks are precision crafted in our State of the Art manufacturing facility located in California using quality materials. Tank bolts have a tensile strength of at least 120,000 pounds per square inch and are available in three finishes: hot-dipped galvanized, encapsulated & stainless steel. To ensure our tanks provide years of leak free service, we use a heavy duty synthetic rubber gasket to seal between tank staves. For resistance to a variety of liquids such as water, wastewater and oil, several gasket materials are available including ethylene propylene diene monomer (EPDM), Buna N and Viton by DuPont.  Our tank gaskets are precision punched to fit exactly and are formulated to remain flexible and not separate from the tank surface.

Superior Tank was the first to apply thermoset fusion bonded powder coatings to bolted steel storage tanks.  Our factory power coating process is very precise and results in a finish with greater resistance to corrosion, cracking, chipping and scratching.  For improved coating adhesion and greater durability, steel staves are prepared to “Near White” standards then sprayed with SiZr seal. Laboratory testing has proven the SiZr seal increases the coating bond to the steel and the coating is damaged the SiZr seal prevents corrosion spread and undercutting.  After the SiZr seal is dried, the powder coating is electrostatically applied to the steel panels ensuring 100% coverage.  The steel parts are then heat cured to permanently bond the powder coating to the steel. For maximum durability the coating is specifically formulated to the application. The exterior receives a TGIC polyester type of powder coating for superior UV resistance.  For immersion service, epoxy type power coating which is AWWA, NSF & FDA approved is applied to the interior of the tank.  As well as factory powder coated steel tanks, we also manufacture hot dipped galvanized, stainless steel and black (bare) bolted steel storage tanks.

Bolted Steel Tank Installation

In addition to manufacturing bolted steel tanks, Superior Tank can install new steel tanks. We employ our own installation teams based in California and Texas and we hold General Contractors licenses in a number of states throughout the US.  Our installation crews specialize in bolted steel tank erection for hassle free installation and we make job site safety a priority.  As we are the manufacturer as well the tank erector, we can install a tank in less time and you can rest assured the tank will be installed properly.

Quick and Easy to Install

By fabricating and installing our own Bolted Steel Tanks, Superior Tank can often meet the tightest of schedules with our Tank In A Box. Also, since Bolted Tank parts are standardized and interchangeable, costly delays to repair damages cause by inclement weather can be avoided. Standard Bolted Tanks have flat steel floors and steel cone roofs. Open top, cone bottoms or embedded shell tanks are also available.

Tank In A Box

For customers installing their own bolted steel tank, we offer local or international shipping of our steel tanks. When our tanks are shipped outside of the United States, the complete tank kits are packaged inside a standard shipping container. This “Tank in A Box” is delivered directly to the job site for fast installation.
