“Der Schwur des KÄRNAN” ride at the HANSA-PARK in Northern Germany is unique and has no equal. The Hyper-Coaster run is 1,235 metres long and has a 79-metre high tower at its centre. The carriages turn upside down as they travel through the dark, then dropping an impressive 67 metres into the depths. One thing is clear here: safety is a top priority.
A latticed staircase made from 30 tonnes of hot-dip galvanized and powder coated steel was erected inside the tower to provide access for workers to carry out maintenance and service work on the ride.
This means that it is not necessary for the park operator to carry out any maintenance measures on the stair structure itself over the long term. The demands made on the durability of corrosion protection were analysed before the order was placed. Due to the fact that the stair structure is located inside the tower, the customer wanted ZINKPOWER Coating Standard to be applied to the steel elements. The steel components were therefore hot-dip galvanized in accordance with DIN EN ISO 1461, chemically pre-treated, after which a single layer of powder coating in RAL9005 was applied using a weatherproof polyester powder coating. In total the corrosion protection is around 200 µm thick.
