MPA Steel Erection delivers precision structural steel erection for commercial, industrial, and large-scale projects.
What started as Bonnco Steel Erection in 1982 with a single job has grown into one of the region's most trusted steel erection contractors. Rebranded as MPA Steel Erection in 2003, we've spent over four decades building our reputation one project at a time — working alongside general contractors and owners from the ground up, handling complex iron work with the same grit and commitment we started with.
From multi-story commercial frames to massive industrial structures, our crews bring the expertise, equipment, and work ethic to get iron in the air safely and efficiently.
Full-scale erection of structural steel frames for commercial, industrial, and institutional buildings — from single-story to high-rise.
Stairs, ladders, handrails, mezzanines, canopies, and all secondary structural steel components installed to spec.
Roof and floor metal decking installed with precision and speed — fully coordinated with concrete and MEP trades.
Jim got his start at Bonnco during summers in high school in 1985. After returning from an LDS mission in Detroit, Michigan, he joined full-time in 1989 and worked his way up to Project Manager by 1996, overseeing all field operations. In 2003, Jim's father Lou Bonner retired and Jim, along with a fellow project manager, purchased Bonnco and rebranded it as MP Associates. Jim has been running MP Associates Steel Erection ever since.
Dray started working for Bonnco straight out of high school in 1992. Over the years he worked his way through the ranks, becoming Project Manager in 2015 and taking on full oversight of all field operations. When his father retired in 2022, Dray stepped up as Owner and has been leading MP Associates Steel Erection ever since.
