Durable Corrosion Protection for a More Resilient Infrastructure

Vossloh protect: Sustainable Coating Solutions for Critical Rail Applications

Corrosion is one of the invisible yet costly adversaries of rail infrastructure. Whether in tunnels, on the coast, in industrial areas, or under extreme temperature conditions – wherever steel components are exposed to aggressive environmental influences, risks arise for safety, availability, and cost-effectiveness. This is precisely where Vossloh protect comes in: The innovative coating system offers long-lasting protection for high-strength steel components against corrosion – even under heavy chemical stress and mechanical load. 

This addresses the central challenges of modern mobility: longer lifecycles, reduced maintenance costs, and greater resilience under real-world extreme conditions. 

Why Vossloh protect?

The premium Vossloh protect coating was specially developed for tension clamps, screws, and other highly stressed components of rail fastening systems. Thanks to its unique material composition based on zinc and aluminum flakes, it provides cathodic corrosion protection, meaning that even if damaged by ballast impact, the corrosion protection remains active. Even after years in the track, the results speak for themselves: no formation of red rust, no loss of function, and no compromises on safety or durability. 

Advantages at a glance:

  • Maximum corrosion protection even under extreme conditions (C5-H according to ISO 12944) 
  • Global applicability – in tunnels, ports, tropical environments, industrial plants, coastal areas, or mountain regions 
  • Compliance with the strictest environmental standards – free from chromium compounds and heavy metals 
  • Reduction of lifecycle costs due to longer durability and less maintenance 
  • Efficient use of resources thanks to minimal coating thickness and environmentally friendly application 
  • High resistance to chemicals such as acids, alkalis, diesel, AdBlue, or brake fluid 
  • Color customization for easy identification within the system 

Designed for extreme conditions – tested for global deployment

Vossloh protect has been rigorously tested in numerous laboratory and field trials under realistic conditions—from climate change simulations and Kesternich tests with sulfur dioxide to media resistance testing with aggressive industrial fluids. The results are convincing worldwide:
