Xiangshan Port Bridge Deploys Graphene Anti-Corrosion Technology
Massive commercial application of an innovative graphene-based anti-corrosion coating has been carried out on the Xiangshan Port cross-sea bridge located in Zhejiang Province, east China. Spanning roughly 8.28 kilometers across the port, this architectural feature functions as part of the nation’s inaugural cross-sea suburban railway while presently claiming the title of the world’s longest-span ballastless-track cable-stayed railway bridge.
Marine Environment Challenges and Coating Performance
Cross-sea bridges face severe environmental hurdles, including high salinity, high humidity, and intense ultraviolet radiation. These harsh marine conditions threaten the weather resistance and corrosion protection of the structures, as well as the overall service life of standard protective materials. To combat this, researchers at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences, alongside an incubated enterprise, developed heavy-duty graphene-modified anti-corrosion coatings for the Xiangshan Port project. The formulations provide sound barrier performance, strong adhesion, and high salt-spray resistance to mitigate steel corrosion in marine atmospheres.

Infrastructure Impact and Global Deployment
By doubling the service life of conventional anti-corrosion coatings, the new technology substantially cuts maintenance costs and safety risks, according to the developer. The large-scale rollout is designed to enhance the safety and durability of cross-sea rail infrastructure. Beyond Zhejiang Province, the same coating technology has been utilized in the Jakarta-Bandung High-Speed Railway in Indonesia and a dual-fuel power station in Cambodia. NIMTE indicates that the material holds significant promise for broader applications in marine engineering, high-end equipment, and aerospace sectors.
