Aluminium corrugated is used for this tank roof instead of gal or colour-bond sheeting. A new aluminium roof structure was installed on top of the existing steel roof support beams with appropriate isolation between dissimilar metals with new corrugated aluminium sheeting for the roof. The reasoning is a longer roof life compared to the original steel which rusts out from the chlorine gas introduced into the water supply.
A STORMASTER-ESE-30-SS lightning protection system was supplied and installed. To facilitate equipotential bonding we maintained the original tank LP earthing.
