Why use Galvanized steel rather than Zincalume steel for your tank walls?

Galvanized Water Tank

Today, there are other suppliers of poly lined steel tanks, many claiming that Zincalume steel will outlast Galvanized materials in this application. Simply put, Aquamate knows this is not true.

When a tank is full, the liner is pressed up against the inside wall, causing condensation to be trapped between the liner and the tank wall. The corrosion to Zincalume steel is inevitable due to the moist conditions & the lack of oxygen (air), which Zincalume steel requires to form its stable oxide films that would normally prevent further corrosion.

For example, Zincalume steel roofing & wall cladding on a barn will outperform Galvanized steel because the steel is able to “breathe” (form its stable oxide films). However, if the Zincalume steel wall cladding comes in contact with the ground rapid corrosion occurs. This is due to the moisture in the ground and the fact that the steel is unable to breathe. That is why steel barn manufacturers use only galvanized steel for the posts which will be buried ie moist conditions and unable to breathe. The same example is found in fencing and all other structures made of steel.

There is one overriding reason why some tank companies promote Zincalume steel in this application, cost. On average Galvanized coated steel costs 33% more than Zincalume steel. This is because the Galvanized material that Aquamate supplies has a minimum Zinc coating of 1.45 oz/ft2 whilst Zincalume steel only has a minimum Zinc/Aluminium coating of 0.50oz/ft2. That’s 3 times the coating mass of Zincalume steel!

Another reason is because they can offer a range of colors using the same cheaper G40 coated material roofers use when they supply a curved veranda. Aquamate supplies a variety of colors because we have our steel supplier manufacture the more expensive Galvanized G145 material with a colored finish. This material is exclusive to Aquamate.

If you’re still not convinced Galvanized material would outlast Zincalume steel in a poly lined steel tank then we suggest you obtain independent advice. Ask a traditional tank maker, a barn builder, a fence contractor or a corrosion engineer as to why they would use only Galvanized material in an enclosed moist environment.
