An old railway bridge between Voikkaa and Kuusaa has been used as a non-motorised traffic route since the 1980’s. The renovation started in April 2019 and it has progressed well, with one third of the bridge coated so far with Nor-Maali products. Application is done according to the Finnish LIVI B.1 SILKO painting system.

Our customer Korroosiotyö Korkal is responsible for the coating work done on this over 220-meter bridge. The total area to be coated is approximately 30 000 square meters.

The project is due to be completed in September 2019.
