Allium Engineering is revolutionizing infrastructure with its innovative technology that triples the lifespan of bridges and structures. Their method involves using stainless steel cladding to make rebar resilient to corrosion, significantly reducing the need for frequent repairs.
By eliminating corrosion, infrastructure can last much longer, decreasing the frequency of repairs and reducing carbon emissions. The company's technology is designed for easy integration into existing steelmaking processes. This innovation addresses the critical issue of aging infrastructure, as highlighted by the American Road and Transportation Builders Association, which reports that one in three U.S. bridges needs repair or replacement.
Allium Engineering adds a thin, protective layer of stainless steel to traditional steel rebar, enhancing its resistance to corrosion. Already, approximately 100,000 pounds of Allium's stainless steel-clad rebar have been utilized in various construction projects across the United States. The company is confident in its ability to scale the process rapidly alongside steel mills, contributing to more resilient, affordable, and sustainable infrastructure for the future. According to Allium co-founder and CEO Steven Jepeal PhD '21, this technology extends the typical bridge deck lifespan from about 30 years to 100 years or more.
