Switzerland-based steelmaker Swiss Steel Group has announced that it has supplied 2,500 mt of corrosion-resistant rebar for the reconstruction of Helgoland’s West Pier, a key coastal protection project.
Approximately 2,500 mt of Top12 reinforcing steel from Swiss Steel Group is being used in the renovation of the western wall of the South Harbor on Helgoland.
The 563-meter-long West Pier serves as a protective structure for the harbor, which is considered critical infrastructure for the island located in the German Bight.
Corrosion-resistant steel designed for marine environments
Top12 reinforcing steel has been specifically developed for use in environments exposed to high chloride levels.
The material offers significantly higher resistance to chloride-induced corrosion compared to conventional reinforcing steel, making it suitable for:
- Splash zones
- Tidal areas
- Marine infrastructure
This durability is essential for coastal protection structures exposed to harsh sea conditions.
Production supported by group-wide operations
The production of Top12 involves multiple facilities within Swiss Steel Group’s network. Billets are melted at Deutsche Edelstahlwerke in Siegen, hot-rolled at Steeltec in Switzerland, and finished at the Hagen plant, where the material undergoes pickling and coil processing.
The Helgoland project combines corrosion-resistant steel with clinker-reduced concrete to lower its environmental impact.
The Top12 reinforcing steel is produced using an electric arc furnace route, contributing to reduced carbon emissions compared to conventional production methods.
