New Millennium is a division of Steel Dynamics, Inc., one of the largest steel producers in America, and named one of Fortune magazine's World's Most Admired Companies. Established in 1999, we have grown to become the second-largest provider of steel joist and metal deck building systems to the U.S. market. Our engineering, manufacturing and service facilities are located across the United States. We are a progressive organization, providing excellent benefits and opportunities for career advancement.

Founded in 1999 in Butler, Ind., New Millennium Building Systems began with one clear mission: To be your trusted collaborator for the design, engineering, and supply of structural steel joist and deck building systems. Today, we continue to earn your trust by addressing the need for early, team-based project collaboration. We assist in the specification and engineering of the right steel building systems so we can together simplify and expedite the delivery of more cost-efficient projects. We help you achieve your architectural vision and realize a range of project and performance improvements.

When we say "together, let's build it better, " we're talking about everyone involved in a steel building project at every step. We are as invested in the success of a project as the owners, developers, fabricators, erectors, architects and engineers. We consider their point of view. We are mindful of their interests. We are keenly aware of the challenges they face. Those perspectives feed our collaborative approach throughout a project. Before our steel joists, steel deck or long-span composite systems are even delivered, we're there for early assistance on right system selection and engineering.
