Stainless Steel Water Tanks 304 / 316 Grades
304 Grade Stainless Steel Tanks
Grade 304 stainless steel is generally regarded as the most common austenitic stainless steel. It contains high nickel content that is typically between 8 and 10.5 percent by weight and a high amount of chromium at approximately 18 to 20 percent by weight. Other major alloying elements include manganese, silicon, and carbon. The remainder of the chemical composition is primarily iron.In most applications the steel is used where its corrosion resistance gives long lasting appearance and service life. The ease of cleaning and of maintaining a hygienic surface on the steel make it excellent for many purposes.
Our 304 Grade is a good choice if you live inland away from the salt corrosive sea.

316 Grade Stainless Steel Tanks
Grade 316 Stainless Steel is a metal alloy, made up of steel mixed with elements such as chromium, nickel, molybdenum, silicon, aluminum, and carbon. Iron mixed with carbon to produce steel is the main component of stainless steel. Chromium is added to make it resistant to rust.
Water tanks made from Grade 316 are perfect for sea-side environments. They can be easily cleaned, resists organic chemicals, and a wide variety of inorganic chemicals.
Here’s a tip! Fresh water and air react with the chromium oxide compound that forms a passive layer over the steel, if damaged the passive film reconstitutes itself. So make sure you give your 316 Stainless Steel water tank an occasional rinse with rainwater.

Stainless Steel Water Tanks FAQs
Why stainless steel?
There are many reasons you should consider buying a stainless steel water tank.
They include:
- They come with a 30-year warranty for corrosion and so are cost-effective over time.
- The minerals used in stainless steel are valuable and so can be recovered and recycled.
- They are being designed into structures by builders and architects because they look good.
- University research shows they hold their structural integrity during a bush fire.
- Stainless steel keeps the water cool which helps reduce the growth of bacteria and algae.
- Stainless steel does not leech impurities into the water which makes it hygienic to drink.
Are rainwater tanks worth it?
Rain can be harvested from your roof for example, instead of flowing away from your property, via a pipe from the gutters for example into the top of the tank via an inlet strainer. If you approximate the cost of the tank as say $2500 and it is serviceable for over 30 years, then the cost is well less than $2.00 per week to provide water to your household, your stock, your crops or your lawn and/or garden.
Do you connect the tanks up?
No. We suggest you get a local plumber to connect them up. That way you have a local expert to make them compliant to local conditions.
Are the tanks resistant to bush fires?
Yes. University research shows that both Stainless steel and Aquaplate/Colorbond tanks maintain their structural integrity during bushfires.
Does Stainless Steel Cost More?
On average, round stainless steel tanks made from Premium grade 304 stainless steel are approximately $500 to $1000 more than the equivalent tanks made from Aquaplate/Colorbond.
For example, a 10,000 litre round tank made from stainless steel is approximately $2900 whereas a similar one made from Aquaplate/Colorbond is approximately $2200.
The price differential is slightly more for slimline tanks because of the inclusion of internal stainless-steel rods to strengthen the slimline shape of the tanks.
The price differential is also greater if Marine grade 316 stainless steel is used to construct the tanks.
For more information on pricing see our example price lists .
What fittings come with the tank?
Three fittings come with your tank. You will be asked where on each tank you want them.
They are:
- A 400mm inlet strainer with light guard which allows the water from your roof for example, into the tank, with protection from the sunlight and mosquitoes.
- An overflow attachment which is a round plastic outlet which can be either 90 or 100mm in diameter and which come with mosquito proofing.
- A 25mm outlet with a ball valve located at the bottom of your tank.
What other fittings are available?
There are a wide range of additional fittings we can provide. One example is we can install a bucket height tap on the side of your tank.
Can the tanks be made to be fire-fighting compliant?
Yes we can fit the tanks with the required fittings to make them firefighting compliant, with a Storz fitting for NSW or the Camlock for Qld.
One particularly efficient tank we can build is where the normal outlet system is built a certain distance up the side of the tank so that you always have 10,000 litres in the bottom section of the tank in case of fires, while still using the water in the top of the tank for normal use.
