Water Treatment & Storage
Some of the earliest applications of aluminium sheeting in Australia relate to water storage facilities.
Water authorities around Australia generally select materials on the basis of a maintenance free design life of 60 years.
Our aluminium products meet this rigorous selection criteria. Permalite® products have been and continue to be an integral part of Australia’s potable water supply system.
