Infrastructure that lasts a lifetime

Transforming rebar for a more resilient, affordable, and durable future

At Allium, we revolutionize critical infrastructure with our innovative process for creating stainless steel claddings for steel construction materials. Our breakthrough rebar technology prevents steel corrosion, delivers exceptional value, and significantly reduces carbon emissions.

Allium is a US-based startup founded by two MIT Ph.D. graduates that designs and manufactures coated rebar technology to create infrastructure that is more resilient, affordable, and sustainable.

Our Technology Advantage

Our proprietary cladding process integrates directly into modern steel mills and produces a durable, bendable, robust corrosion protection for 100+ year lifetimes.

Extended Life

By eliminating corrosion, our technology extends structure lifespans by up to 100 years and beyond

Lower Cost

Our solution costs a fraction of alternatives while dramatically reducing maintenance and replacement expenses
