Exclusive: One startup’s paper-thin stainless steel could change how bridges are built
A What happened
Allium Engineering has introduced a novel solution to combat rust in concrete structures, particularly bridges, which are highly susceptible to corrosion due to exposure to water and salt. The startup's stainless steel-clad rebar offers a cost-effective alternative to traditional stainless steel rebar, which is often too expensive for widespread use. By applying a thin layer of stainless steel over regular rebar, Allium aims to extend the lifespan of bridges from 30 to 100 years. This innovation not only promises to reduce maintenance costs but also allows for the use of greener cements, as the rebar's corrosion resistance minimizes the need for additional concrete. Allium's rebar has already been utilized in several bridge projects, demonstrating its practical application and potential to transform infrastructure construction.

Key insights
