7 benefits of using plastic tanks over steel tanks

Traditionally steel tanks have been the first choice for water storage, but they have limitations. For one thing, steel tanks are at the mercy of the elements and corrosion is a common issue. Discover the benefits of plastic tanks:

With the variety of rotomoulded polyethylene tanks available on the market it means that you can avoid corrosion and have a tank with a longer life. We look at 7 practical benefits of using plastic tanks over steel tanks.

1. Plastic tanks weigh less

Steel tanks weigh a lot more than plastic tanks and usually need the help of a crane to move them onto your property. In comparison, plastic tanks are lightweight and can be moved into position by hand, which is an advantage if there is hilly or rough terrain on your property.

2. Easier to position

The surface upon which steel tanks sit need significant preparation before the tank is installed. This can involve expensive steel rings and a concrete base to keep the bottom from rusting. Plastic tanks can sit on any flat surface as long as there’s nothing sharp underneath, some can also be positioned underground away from sight.

3. A wider variety

Steel tanks are circular with a coned roof. They may change in diameter but the basic shape is the same. Plastic tanks on the other hand, come in a wider variety of shapes and sizes. From rounded, to slimline, there is sure to be a plastic tank to suit your needs.

4. Blend better with the landscape

Plastic tanks come in a greater variety of colours than steel tanks. They can stand out or blend in with your home and landscape depending on the look you’re going for. They are suitable for both rural and urban use.

5. They won’t rust

As mentioned, the biggest advantage of plastic tanks over steel tanks is that they don’t rust over time and need to be replaced. Their longevity is also due to the fact that they are made to withstand the Australian climate. UV-inhibitors protect the tanks from degradation from sunlight.

6. Strong and durable

Steel tanks are hardy, but as their parts are welded or bolted together, side seams, joints and weld lines can become weakened over time. The rotomoulding process bonds plastic through speed and heat, with the use of a mould, so the final product is more durable and less likely to fall apart.

7. Better for drinking water

Steel tanks are galvanised with a zinc wall which, while not a health risk, can affect the taste of drinking water. Studies on some steel tanks have also shown a harmful level of lead. Many people are not comfortable in taking this risk with their drinking water. Plastic tanks are manufactured from food-grade safe, BPA-free polyethylene plastic so they’re 100% safe for storing drinking water.
