When you look at your investment over the lifetime of the product you may be surprised at what you find. Considering the average 15-year life span of a standard painted steel tank, not including the cost of maintenance, delivery or replacement, the comparison is astounding. In 45 years you would be purchasing a third painted tank, whereas your stainless tank would still be providing the same quality liquid storage as the day you purchased it.

Built to Last

The alloying composition of stainless steel makes it naturally durable and corrosion resistant

Eco-friendly & Maintenance Free

No painting or coating requirements. No flaking, splitting or fibers ending up in your fertilizer

Exceptional Value

Even in 45 years your Nstor stainless tank will be providing the same quality liquid storage


"I was surprised to hear of a stainless steel liguid fertilizer tank with pricing comparable to fibreglass! The Nstor tank looked great and stainless steel tanks are a multi-generational investment so I decided to purchase one. Within two weeks of having the first Nstor tank on the yard, I ordered three more! This is a stellar product and has incredible value for the price!"

“Westcap AG’s stainless steel N-Stor tanks are a superior product, and they were an excellent company to deal with. For our farm this was a great investment, one that will see our operation through to the next generation.”
