Allium

Allium Engineering is a climate-tech startup based in the U.S., founded by two MIT Ph.D.

graduates. The company specializes in designing and manufacturing stainless steel-clad rebar technology aimed at enhancing the resilience, affordability, and sustainability of infrastructure. The core product, stainless steel-clad rebar, offers corrosion resistance to extend the lifespan of infrastructure such as bridges and concrete structures. Allium's proprietary cladding process can be integrated into existing steel mill operations, producing durable and bendable corrosion protection designed for over 100 years of use. This innovative approach can significantly increase the longevity of critical infrastructure while reducing maintenance needs and lowering carbon emissions associated with steel and concrete production. Allium's stainless-clad rebar has been utilized in various construction projects across the U.S., including notable applications in bridge construction. The company actively engages with partners in the steel and construction supply chain, including steel mills and infrastructure builders, to promote its rebar solutions.
