HIGH GRADE TANKS BUILT TO LAST
IT’S NOT JUST A TANK, IT’S THE STRONGEST TANK IN THE
As station owners we couldn’t find a product on the market which could withstand the
harsh conditions we endure here in the Northern Territory.
We decided to design and build our own tank which could withstand the environment
with confidence. It had to be made out of thicker material, reinforced joins and liners
which could handle any water source and ground condition.
With the success of installing over 2000 tanks in the Northern Territory we have
developed our operation to now be able to cater to other regional demands.
GNT not only was designed with strength and durability in mind, it is practical and comes
with high quality standard inclusions.

Great Northern Tanks uses Aluzinc coated steel which has superior long-term corrosion
resistance in most atmospheric conditions.
The aluminium zinc alloy coating is applied in a similar way to traditional galvanised
steel. B way of a continuous hot dipped galvanised process that gives a coating on both
sides of the material of 55% aluminium, 43.4% zinc and 1.6% silicon.
This gives the steel much improved corrosion resistance compared to traditional
galvanised material through the joint action of the sacrificial cathodic action of the zinc,
and the barrier of aluminium present on the surface. This gives the material up to 6 times
(500%) more corrosion resistance to normal zinc galvanised coatings, making it i
