Founded in 1991, M&N Structures has dedicated our existence to a single purpose: providing a hands-on, relationship-driven approach to design and structural steel fabrication. The tools and tactics have changed over the years, but our collective passion for serving our customers remains unaltered. Our tight-knit team and family-driven culture are one of our core strengths and with that power, we bring our unique approach to structural steel fabrication and all of our design-build projects throughout the Midwest.
