AQUAPLATE® steel has been developed by BlueScope Steel especially for water tanks. It has a food grade polymer skin bonded to its inner surface which helps ensure that your water tastes clean and fresh - free from any tainting from the tank itself. It's for this reason that a tank made from AQUAPLATE® steel stands out from the rest. AQUAPLATE® is backed by a 20 year warranty from BlueScope Steel.

A tank made from AQUAPLATE® steel is the only steel tank to comply with tough Australian Standard on the use of plastic materials for food contact use (AS 2070 part 2).

You get all the advantages of a material that is strong, lightweight, corrosion resistant and durable. It won't crack as a result of aging or sun exposure, and it's the ideal choice for bushfire-prone locations.
