Frequently Asked Questions
What are galvanised steel water tanks?
Galvanised steel water tanks provide an economical solution for storing water and various other liquids.
Designed specifically to hold large quantities, they are commonly used for agricultural, industrial and domestic applications – particularly rainwater harvesting, fire protection, livestock irrigation and pesticide storage.
In certain countries, galvanised steel water tanks are used for potable (drinking) water and wastewater applications too.
Do galvanised steel water tanks rust?
Galvanised steel water tanks are tough, reliable and long-lasting. They are finished with a galvanised coating to prevent rust and corrosion.
Most galvanised steel tanks also come with an inner poly-lining, which prevents rusting and corrosion.
However, the lining of the tank could become dislodged, and when the contents stored inside the galvanised steel water tank come into contact with other metals, its effectiveness may be reduced.
Therefore, it’s crucial that galvanised water tanks are properly maintained by qualified engineers to continue their lifespan.
How long will a galvanised steel water tank last?
Unlike plastic tanks that are prone to failure in extreme heat, galvanised steel water tanks have a life expectancy of 30 years or more – as long as they are maintained correctly.
Although galvanised tanks are more durable than other materials, and will maintain their structural integrity for years to come, several factors can affect their lifespan. These include the geographical location of the tank and the use of the tank.
For example, if your galvanised steel water tank is kept near the sea, the salty air will cause it to corrode much faster. Likewise, if the tank is installed on uneven ground, this will affect its stability and longevity.
It’s also worth bearing in mind that, if you use your tank for clean water, it is likely to last longer than a tank used to store chemicals. And if a galvanised steel water tank is used for potable water storage, it needs to be fitted with a food-grade tank liner. This will ensure the long-term integrity and prevent oxidised metals from making their way into the water supply.
Are galvanised steel water tanks expensive?
Though it depends on the manufacturing brand, size and style, galvanised steel water tanks are slightly more expensive than their plastic counterparts.
