Excellent Product & Service

“Excellent product and very good support service.”

The quality of the build was excellent

“The tank you built for us in 2002, has absolutely no wear on the Powder Coating or any other feature of the tank. The quality of the build was excellent, we automatically go to Superior for our tank needs as it is a known quantity.”

Excellent Work

“Just wanted to let you know that your work crew was excellent. Thanks for your professionalism.”

Jack C.

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.

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

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 .”

Chime & Flat Panel Bolted Tanks

Flat and Chime Panel Tanks  

The Choice Is Yours!

Superior Tank offers both chimed and flat panel bolted steel tanks to meet the various needs of our customers. Our chimed steel tanks are designed to the American Petroleum Institute (API) 12B standard and range in size from 4,000 to 2,000,000 gallons.  In addition to petrochemical and oil storage, our chimed bolted steel tanks are well suited for storage of potable water, wastewater, water for fire protection and dry bulk materials. When additional capacity is needed, one of our flat panel bolted steel tanks can offer up to 3,500,000 gallons capacity without compromising strength or durability. Unlike other flat panel designs on the market, our steel does not thin at the edges, therefore maintaining maximum strength throughout the panel.

Shared Features

Both our chimed bolted steel tanks and flat panel tanks are manufactured to the same high quality standards and provide the features and benefits:

    • • Gaskets of heavy duty EPDM, Buna N or Viton eliminate gaps and mastic ooze
    • • Single, double and triple row gaskets prevent leaks between rows
    • • Powder coated finish on BOTH interior and exterior for greater durability
    • • Powder coated parts and fittings for outstanding corrosion resistance
    • • Hot dipped galvanized steel tanks and components also available
    • • SiZr (Silica Zirconium) underseal to prevent coating undercutting and the spread of corrosion when coating damage occurs due to dropped tool or thrown rock
