Slimline Rainwater Tank Differences
Slimline rainwater tanks can be found in a range of material substances and shapes including Slimline Aquaplate Steel Tanks or Modline Aquaplate Steel Tanks, Slimline Poly Tanks (polyethylene plastic) and Stainless Steel Tanks (SS 304 or SS 316). Here are some important differences:
- Poly slimline water tanks: Many people opt for poly as they are cheap, quite robust to impact damage and won't rust. Unfortunately, poly slimline tanks will generally take up more space than a steel tank, since they require thicker walls for support. Poly tanks also expand and contract over time, which is something to keep in mind if you have restricted space. It is also important to consider the shape of your tank. Slimline tanks require greater support than round tanks, since water is more unevenly distributed inside. The thinner your tank, the greater the stress that is placed on the tank walls. Due to this, slimline poly tanks generally stop at about 5000 litres in capacity. Some high capacity slimline poly tanks may come with an external steel support structure, which helps to prevent warping and provides a longer life.
- Aquaplate steel slimline tanks: Also commonly referred to as Colorbond steel tanks. A main difference though is that Aquaplate steel sheets are fabricated by BlueScope with a thin food-grade poly layer on one side, which allows the steel tank to safely store rainwater. That said, Aquaplate steel rainwater tanks in a slimline shape can be had in capacities right up to 11,000 litres. If you are having problems getting the right size tank for your space, Aquaplate steel tanks can be made to measure. As steel walls are thinner than poly tank walls, they will also take up a lesser footprint and weigh less. While Aquaplate slimline steel tanks aren't good to place near the ocean, these tanks endure the Sun better and can also be used for fire tanks.
- Stainless steel slimline tanks: These are the most expensive slimline tanks money can buy, but then they carry the highest legitimate warranty of 30 years. They are strong, can be made to size, are fully recyclable, and many like them because they are fully steel with no plastic walls. People often also tell us they prefer the look of a steel tank, and truth be told, they do look nice.
There are two main grades of stainless steel used in rainwater tanks:
- SS 304, which is the steel often used in kitchen sinks, and
- SS 316, which has significantly higher resistance to salty air.
