Hartwig Mechanical’s Solutions Are Engineered for Accuracy and Performance

Hartwig Mechanical’s custom metal fabrication services are all about fit and function. We start by selecting the right materials for your environment, whether carbon steel, stainless, aluminum, or specialty alloys, and engineer each component to meet strict tolerance and strength requirements. From mechanical frames to custom ductwork, our team uses prefabrication methods that reduce jobsite variables, improve safety, and shorten project timelines. Every cut, weld, and assembly is built with intention because we know how critical these components are to your system’s reliability.

We have two dedicated prefabrication shops: one mechanical shop in Loves Park, IL, and a plumbing shop in Harvard, IL. These facilities allow us to maintain strict quality control from start to finish. Working in these controlled environments streamlines production and ensures clean, code-compliant results. From custom welding and fabrication to heavy-duty structural builds, our high-quality solutions fit your system and hold up under pressure.

Hartwig Mechanical Is Ready to Meet Your Specifications

As with all of our design-build services, Hartwig Mechanical’s metal fabrication services are developed for optimal field performance and installation efficiency. Every project is built around your system’s unique layout, load demands, and long-term operating goals. By pairing welding and custom fabrication with prefabricated components, we help eliminate jobsite guesswork while improving safety and schedule control. From base plates to beams to fully-integrated assemblies, we fabricate exactly what your system needs.

  • Strength and Precision That Hold Up in the Field

    Educational facilities, hospitals, and apartment buildings alike, we fabricate brackets, frames, supports, and full system components engineered for real-world load conditions and repeated use. Whether your project calls for structure or specialty metalwork, our fabrication teams deliver durable results.

  • Supporting Mechanical Systems With Fabrication That Fits

    Our fabrication work supports everything from custom ductwork to rooftop units and process systems. It’s not just metalwork, but an engineered solution matched to the needs of your mechanical build.
