Steel vs Alloy

Is that water tank steel or aluminium?

It may be easy to spot an Allquip steel tank with a pressed square design, but the differences between our elliptical steel and alloy tanks are much more subtle.

These two tank materials share similarities in shape and size range, so which one should you choose and why? Here’s a comparison between Allquip’s steel and aluminium tank options…

Tank Material	Constructed from Australian made steel plate.	Constructed from marine grade aluminium.
Standard Sizes	Available in 8,000Lt, 14,000Lt, and 18,000Lt.	Available in 8,000Lt, 14,000Lt, and 18,000Lt.

What else should you know about our steel and aluminium water tanks?

Your new Allquip steel or aluminium tank will continue to look sleek and professional for years to come. Either tank type is easily refurbished with a coat of paint.

In the long run, alloy water trucks typically have a higher resale value than our steel tanks, which is a direct result of the tank material’s longevity.

Both tank options are premium quality Australian made products that will reliably serve the end-user, even in the harshest operating environments.

When it comes to a tried and tested water tank material, Allquip’s steel tanks have always been a favourite for the traditionalist. In comparison, our aluminium option is newer to the market, but is becoming increasingly popular amongst our government and construction clients due to its increased payload capacity.

So, here’s the test – can you spot the difference?
