In 1970, even before the creation of the ZINGAMETALL BV company, the Swiss ACMV steel
company (Ateliers de Construction Mécaniques de Vevey), created in 1895, has built the
structures for a bridge to be mounted on the R21 railway line, located in Val-de-Travers, over
the Areuse river, for account of CFF, the Swiss Federal Railway Company. The retained and
applied system was ZINGA stand-alone at 180 μm DFT.
49 years after, on 26 September 2019 a visual condition survey was held by the main
contractor OPAN Concept and the paint contractor SABLISOL.
Their conclusions were as follows:
The metal structure of the bridge does not show significant corrosion.
• Small pinpoint areas with surface corrosion (due to initial low DFT).
• Deposits of rusty iron filings/stains from the rails.
• Painting of the bridge structure is in good to very good condition.
• No areas of heavy rust or swelling were observed.
