The Zinc helps slow down corrosion, but depending on environmental factors, a galvanized tank may last well under 5 years, particularly if the roof of the structure capturing the rainwater is made from Zincalume.
Zincalume® was originally used for roofing. It's a a mix of 55% aluminium, 43.5% zinc and 1.5% silicon bonded to steel.
Colorbond is Zincalume with a conversion layer applied to the surface of the steel to improve adhesion; then a polyester primer baked on, followed by a top coat of paint that is also baked on.
3. Fiberglass Tanks
As fiberglass tanks tend to allow more light in than other types of tank materials, this can encourage the growth of algae, so they should be painted. Fiberglass can also tend to be brittle, leaving it prone to cracks - something you don't want, particularly in an in-ground situation.
