Precision Millwright Experience
Since our founding, MIC has focused exclusively on heavy industrial millwright work — the precision installation of conveyors, automated storage and retrieval systems, structural steel, overhead cranes, and production-critical equipment. Every member of our field crew holds specialized training in machinery alignment, rigging, and industrial safety. That single-trade focus means your project is handled by technicians who install, align, and commission heavy equipment every day, not general contractors who occasionally take on industrial jobs.
Safety Is Non-Negotiable
MIC maintains an Experience Modification Rate well below the industry average, and our supervisors carry OSHA-30 certifications. We conduct daily toolbox talks, pre-task hazard analyses, and site-specific safety orientations on every project. Our safety record is one reason automotive OEMs and Tier-1 suppliers trust us inside operating plants where even a minor incident can halt a production line worth millions of dollars per hour.
Repeat Customers Exposed to High Standards
More than 80 percent of our revenue comes from repeat customers — automotive assembly plants and distribution centers that call us back because we deliver on time, on budget, and without safety incidents. Clients like Stellantis, Honda, Toyota, Nissan, and Daihatsu rely on MIC to execute during tight shutdown windows when there is zero margin for schedule slippage or rework.
Licensed and Insured in Nine States
MIC holds active contractor licenses and carries full insurance coverage in Illinois, Indiana, Ohio, Alabama, Texas, Michigan, Mississippi, Tennessee, and Kentucky. That multi-state footprint lets us mobilize crews quickly to your facility without the delays of securing temporary permits or out-of-state insurance riders. Whether your plant is in the Midwest, the South, or the Gulf Coast, MIC arrives ready to work on day one.
Single-Source Capability
From structural steel erection and mezzanine construction to conveyor installation, equipment rigging, welding, and fabrication, MIC handles every phase of an industrial installation under one contract. A single point of accountability eliminates the finger-pointing and coordination delays that plague multi-vendor projects, and it gives you one schedule, one safety program, and one team that owns the outcome.
When you choose MIC, you get a contractor that treats your project like its own. We bring the field expertise, safety culture, and project management discipline needed to deliver complex industrial installations on time and on budget. Our estimating team provides detailed, transparent proposals so you know exactly what you are paying for before work begins. From mobilization through final commissioning and punch-list closeout, a dedicated MIC superintendent owns your project from start to finish. Learn more about our team and see why leading manufacturers trust MIC with their most critical installations.

MIC provides heavy industrial millwright services to a wide range of manufacturing and logistics facilities across the United States. Our core expertise spans the following sectors:
Automotive Assembly and Body Shops
We install and relocate conveyors, robot cells, friction-drive systems, power-and-free lines, and body-shop tooling inside active automotive plants. Our crews understand the tight shutdown schedules and strict safety protocols that define OEM and Tier-1 production environments. MIC has completed conveyor and equipment installations for brands including Stellantis, Honda, Toyota, Nissan, and Daihatsu.
Distribution and Fulfillment Centers
MIC installs automated storage and retrieval systems, roller conveyors, sortation lines, mezzanines, and modular in-plant offices for high-volume distribution operations. We work with integrators and end-users to ensure every system is aligned, leveled, and commissioned to exact tolerances so your throughput targets are met from day one.
Heavy Manufacturing and Fabrication
From machine-tool relocation and rigging to structural steel erection and overhead crane installation, MIC supports manufacturing plants that build, stamp, weld, or machine heavy components. We provide certified welding, on-site fabrication, and precision alignment for presses, CNC equipment, and specialty production lines.
Food, Beverage, and Consumer Goods
MIC installs slat conveyors, powered roller beds, and packaging-line equipment for consumer-goods facilities that require sanitary design standards and strict downtime windows. Our field crews coordinate closely with plant operations to minimize production disruption during installation and commissioning.
No matter your industry, MIC brings the same commitment to precision, safety, and on-time delivery. Contact us to discuss your next project.
