Robert S.

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.”

Five Critical Parts For Your Steel Storage Tank

Bolted Tank Parts and Accessories

Every year, we sell hundreds of parts for bolted tanks and welded steel tanks. Even though many ground storage tanks needing parts were not originally manufactured by Superior Tank Co., Inc., we can provide standard replacement components for steel storage tanks or can fabricate custom parts and accessories to fit.


Over the last 32+ years, we have discovered there are five storage tank elements which are key to ensuring your water and oil storage tanks achieve their maximum lifespan:

1 Ground storage tank bottoms
2 Roof rafters
3 Ladders and safety railings
4 Hardware, gaskets and appurtenances
5 Powder coating touch up kits


While these seem to be the fundamental oil and water storage tank components, we have found many ground tanks in the field require one of more of these items.


For example, it is not unusual for welded steel tanks to experience bottom corrosion and subsequent steel loss as the underside cannot be coated. In addition, select hot dipped galvanized bolted tanks which are over 30 years old can experience bottom corrosion and require new components. Our fabrication department will custom manufacture replacement steel tank bottom sections to any size or dimensions to fit either bolted tanks or welded steel tanks.


Other structural members which can fail due to corrosion and steel loss are the roof rafters on welded steel tanks. Commonly, the top of welded tank roof rafters are inaccessible so they cannot be coated and protected against corrosion damage. Sometimes, the corrosion is difficult to see as it is located in hard to inspect areas. Superior Tank can manufacture and install replacement roof rafters and rafter hats for welded steel tanks and as well as bolted tanks if they are needed.


Superior Tank can also craft new railings and ladders to upgrade your water or oil storage tanks to meet current safety regulations and allow your steel tanks to remain in service. Safety upgrades will also protect your employees from injury and prevent safety violations. Our exterior ladders are available with or without backguards and in various finishes and our railings are custom manufactured to fit the specific steel tank. All of the safety equipment we supply complies with the latest codes and government requirements for use with steel storage tanks.


If replacement hardware or new gaskets are ever needed for your bolted tank, we stock a wide variety to fit various sizes. We offer EPDM gaskets for water storage applications as well as Buna-N and Viton gaskets for oil storage tanks. In addition, we can fabricate numerous ground storage tank appurtenances such as nozzles, overflow piping, roof vents, manways and roof hatches.


Preserving your water and oil storage tank coating is important to minimizing corrosion, maximizing coating lifespan and keeping your steel tanks looking new. We offer touch up kits to patch any nicks or scrapes in your powder coated bolted steel tanks caused by thrown rocks or dropped tools after the bolted tank is installed. Various colors are available to match the original storage tank color.
