3x boost: Scientists increase bridge lifespan with corrosion-resistant steel

U.S. scientists have developed a technology that can triple the lifespan of bridges and structures. Allium Engineering's process uses stainless steel cladding to make rebar corrosion-resistant, enabling 100-year lifetimes for infrastructure. The technology integrates into existing steelmaking processes, enhancing infrastructure resilience. About 100,000 pounds of Allium's rebar have been used in U.S. construction projects. This innovation could help address the country's aging infrastructure, as one-third of bridges need repair or replacement.
