Since 1936, Zeman Manufacturing Company has been a trusted partner in metal tubing. We engineer and manufacture custom solutions for global innovators in the medical, aerospace, energy, transportation, and foodservice industries. Our expertise in small-diameter, high-performance metal tubing for complex assemblies enables manufacturers to scale production, optimize design, and streamline supply chains.
Based in Lisle, Illinois, our 42,000 sq. ft. facility operates with ISO 9001:2015 and ISO 13485:2016 certifications. We use advanced manufacturing technology, including CNC tube benders and LT Fiber tube lasers, and work alongside our customers to develop the best solutions for their production needs.
Our employees bring decades of experience and a problem-solving mindset to every project. Zeman ensures high-quality results across prototype and large production runs. When others struggle to deliver, we step in with innovative solutions and superior fabrication quality to support project success.
At Zeman Manufacturing Company, our mission is simple: to make things better — for our customers, our partners, and above all, our people.
We manufacture better parts by pairing state-of-the-art technology with a deep understanding of the “dark art” of tube fabrication. Our disciplined processes, decades of experience, and commitment to continuous improvement deliver unmatched precision, repeatability, and efficiency.
We make life better for our customers by solving their toughest tube bending challenges — the ones that strain their teams or overwhelm other vendors. As trusted problem-solvers, we bring peace of mind, cost-effective design insights, and production-ready solutions to every partnership.
We make life better for our people by treating them with respect and rejecting outdated models that limit autonomy and decision-making. Everyone here is empowered to make meaningful decisions and grow in skill, confidence, and prosperity. Whether someone is with us for one year or thirty years, our goal is that they leave better than they came — more skilled, more financially secure, and proud of the work they’ve done.
Because in the end, there are only two roles in manufacturing: those who make the parts, and those who support the people who do. Everything we do is in service of that truth.
Zeman will be synonymous with a better way of doing business.
We excel in traditional business metrics like EBITDA, cost of quality, and on-time delivery. However, numbers alone do not define us. We also excel for our customers and create an environment where working at Zeman is better than working anywhere else.
We reject impersonal corporate culture. Our team operates with purpose, collaboration, and respect. We work as a group of dedicated people who care about each other and the work we do.
By maintaining a strong team, a culture of continuous improvement, and industry-leading performance, we set the standard for what a manufacturing company should be.
Grounded in principles.
We build for the future, investing in people, knowledge, and leadership that will outlast us — as we know a society grows great when the elderly plant trees in whose shade they shall never sit. By mentoring, supporting, and prioritizing long-term success over short-term gains, we ensure that both our team and our company thrive for generations to come.
Adaptability is our strength. Like water, we evolve with the times, embrace change, and leverage new technologies without losing our core identity. No matter the market or economy, we stick together, take the long view, and continuously improve to ensure lasting success.
We act with urgency and discipline, seizing opportunities when they arise and preparing for challenges before they come. Just as farmers work with the seasons, we stay proactive, responsive, and relentless in our pursuit of excellence.
We trust our people to make important decisions, put their personal stamp on the company, and navigate their own paths, balancing autonomy with accountability. Whether making parts or supporting those who do, we take ownership, embrace challenges, and hold ourselves and each other to the highest standards — because we care about doing great work.
