Over 30 years in business with ZERO structural failures. 

From time to time our customers share with us "your competitors tank is thicker so, I'm thinking of going with them".  When it comes to buying a water tank this kind of thinking doesn't give you the full picture.  It doesn't take into account a number of other significant features that position Pioneer Water Tanks as the best value for money water tank on the market.

After 25 years using Australian Pioneer Tanks we continue to choose them for consistent durable quality, innovative design, adaptability to different environments and tidy finish.



How Thick Are Pioneer Steel Water Tanks?

Whilst we acknowledge that some of our competitors water tanks have thicker steel than Pioneer Water Tanks, this is only up to a certain sizes and not relevant across our entire range of tanks. The table below illustrates exactly which tanks EXCEED the steel thickness of our competitors.

Pioneer Water Tanks have been specifically designed by our engineers to put the steel in our tanks where it is needed most.  The success of this engineering feat has been verified by our record of ZERO structural failures in over 30 years of business.

That's just to name a few significant differences between our tanks and those of our competitors. Explore our list of innovations yourself.

Frequently Asked Steel Water Tank Questions (FAQs)

From 12,000 to 500,000 litres capacity, the thickness of our tank walls ranges from 0.8mm to 2.0mm thick.

Our tank range is fully engineered and we have over 30 years of field experience. We put extra steel in the walls when and where it's needed.

Tank life longevity is governed by many factors and tank wall thickness alone isn’t a guarantee the tank will last longer.

Tanks (including fire tanks) need to be engineered for purpose and tank designers consider environmental conditions such as wind, seismic, static and sloshing loads, plus application requirements such as water quality.

All Pioneer Water Tanks are designed to meet or exceed all relevant Australian Standards.

We design our tanks especially for the purpose of storing water. If you look closely, there’s a suite of engineering and service features exclusive to Pioneer Water Tanks that complete your steel water tank package.

There are many extra steps in our design and manufacturing process to improve the longevity of your storage tank. Just count how many things are different on a Pioneer Water Tank and discover the difference.

Exclusive AQUALINER® Fresh antimicrobial tank liner fabric made in Australia and not imported from overseas and fusion-welded here in Australia; Australian steel used in roof trusses, roof sheets, hatches, hook on ladder and tank body.

Exclusive 8-80 V- LOCK® profile for optimal liner support, market leading 150mm diameter overflow, AQUALINER Fresh® double seam fusion-welding system, adaptive swivel foot roof connector, fully concealed bolts and the truly national Pioneer Dealer Direct® network for the highest level of local service, advice and support.

Absolutely. Let’s be super clear. The following metal items from Pioneer Water Tanks are made from Australian steel; tank wall panels, roof trusses, roof sheets, swivel foot truss connector, access hatch, hook on ladder & tank wall covers.

We don’t use imported materials on these items. Be careful. Could other manufacturers shandy their supply chain with imported steel to give you the impression everything is made from Australian steel? Absolutely. But not Pioneer. We are 100% Australian.

No. We only use genuine BlueScope ZINCALUME® and COLORBOND® steel for our entire product range.

If you buy a non-standard COLORBOND® colour tank from another tank supplier be sure to ask whether your tank is genuine COLORBOND® or is it actually powder coated ZINCALUME®.

The more elaborate a profile the stronger you make a sheet of steel.

Pioneer's unique 8-80 V-LOCK® wall profile has a lot of detail and this detail provides exceptional strength and support for the internal liner.

Our innovative wall profile is aesthetically pleasing and it’s become our signature.


Look closely at our steel water tank, our detailed profile is made from the following combination; 8mm vee and 80mm flat profile, repeated and each panel overlaps and locks together in a strong formation to produce the 8-80 V-LOCK® tank wall.

You bet. We think we are the only tank company in Australia with three dedicated in-house design engineers. We know some other tank manufacturers use external engineers to sign-off on their designs, but those engineers don't 100% specialise in water tanks like ours do.

We put those unique skills to good use and feed that talent directly into your product to make your tank last longer. As well as being the leading supplier of rural water tanks in Australia, we are also involved with some of the biggest commercial water storage projects for high profile clients in Australia and around the world. We employ a dedicated Civil & Structural Engineer, and a Materials Engineer.

These engineers are all in-house. All our steel water tanks have been designed to meet or exceed Australian Standards. Call us to find out more.
