Better Rebar

"Startup enables 100-year bridges with corrosion-resistant steel"

Allium Engineering, founded by two MIT PhDs, is tripling the lifetime of bridges and other structures with a new technology that uses a stainless steel cladding to make rebar resilient to corrosion. By eliminating corrosion, infrastructure lasts much longer, fewer repairs are required, and carbon emissions are reduced. The company’s technology is easily integrated into existing steelmaking processes to make America’s infrastructure more resilient, affordable, and sustainable over the next century.
