Description
BRANZ examined the corrosion of aluminium-zinc alloy-coated steel in geothermal environments in a 2-year field trial. At the same time, identical samples were exposed to a marine environment.
The results show that these coatings degrade and fail more quickly in a geothermal environment than a marine environment. Explanations for this are suggested.
