The helideck has a purely functional construction, which is difficult to access for maintenance/inspection of the coating (collars out beyond the building). Besides, the surrounding installations on the roof are made of thermal-galvanised steel. Part of the construction (the “Übberrolschutz”, or low railing on the outside to prevent a helicopter from sliding off the platform) is provided with colour marking in connection with visibility for the helicopter.
The helideck in Cologne has been nominated for the Benelux Trophy for thermal galvanisation 2021. The steel structure competes in the category Laureate in Functional Galvanisation. The BTTG is a biennial architectural competition for projects using thermal galvanised steel.
