What Does Steel Dynamics Do?
Steel Dynamics is a leading industrial metals solutions company that produces lower-carbon, high-quality steel products primarily from recycled scrap. Operating through a circular manufacturing model, the company manufactures a wide range of steel products including flat roll, structural, and long products for industries such as construction, automotive, energy, and manufacturing. In addition to steel production, Steel Dynamics operates metals recycling facilities, steel fabrication plants, and aluminum production operations, serving customers across North America with a focus on innovation, efficiency, and sustainability.
This is a New Millennium Position. Who is New Millennium?
A division of Steel Dynamics Inc. (SDI), New Millennium was founded in 1999 in Butler, Indiana, with one clear mission: To be a trusted collaborator for the design, engineering, and supply of structural steel joists and deck. Today, 25 years later, we’re one of the largest providers of high-performance structural steel joists, joist girders, and deck solutions for commercial steel construction projects.
What Makes This Internship Different?
The Structural Engineering Internship at Steel Dynamics is unique because interns are not limited to observing or performing routine tasks, they are directly involved in projects that impact production, safety, and long-term infrastructure reliability. Unlike many programs that focus solely on classroom-style assignments, SDI interns gain hands-on experience in both design and field work, from analyzing and drafting structural components to inspecting and reinforcing critical infrastructure in active industrial environments. This combination of office and on-site project involvement provides students with exposure to the full lifecycle of civil engineering work in a manufacturing setting. Many interns also work alongside contractors, operators, and engineers, giving them a broader perspective of how civil engineering integrates with operations and business strategy. The result is an experience that goes beyond traditional internships by preparing students to solve real-world challenges and contribute measurable value from day one.
