ZINGA was applied on steel structures of the Airport of Düsseldorf in 1990, namely on a hangar, with a height of more than 30 m, that serves as testing area for the engines of large commercial airplanes and of which the interior side has been insulated with panels. There is a steel structure between the insulation panels and the concrete building. The entire steel structure has been protected with ZINGA as unique system. The applied ZINGA layer thickness was 120 µm. The company DILLINGER STAHLBAU executed the job.
After 4 years the first inspection took place.
There was no formation of rust and the loss of layer thickness was measured to be less than 5 µm. The new hot-dip galvanisation on the contrary already showed traces of oxidation and rust.
