Advantages of steel tanks over poly tanks

We are often asked what the difference is between a steel tank and a poly tank and why steel tanks are more expensive than a poly tank.

To explain, we use the analogy between a steel bucket and a plastic bucket. If you were standing in a hardware shop, you wouldn’t expect a steel bucket to be as cheap as a plastic bucket, right? And you wouldn’t expect a plastic bucket to last as long as a steel bucket, right?

Well, it’s pretty much the same when it comes to tanks. Another advantage with steel tanks is that they can be fully recycled at the end of their useable life, whereas a poly tank will end up in landfill as there is no recycling for poly tanks currently available in South Australia. The main problems that we regularly see with poly tanks is splitting in the walls of the tanks (especially near the tank fittings) issues with the tank being affected by UV exposure as the tank ages and centre poles going through the roof of the tank.

The original split on the right hand side was repaired, however this repair compromised the integrity of the tank and a second split occured.

Poly tanks are manufactured from chemicals, imported from overseas. But our steel tanks are made from Australian BlueScope steel, supporting the Australian steel industry.
