In-House Sheet Metal Fabrication Michigan
Precision-Fabricated Ductwork and Custom Components—Built for Performance
At Danboise Mechanical, we don’t outsource quality—we fabricate it ourselves. Our in-house, computerized sheet metal fabrication facility gives us total control over the quality, accuracy, and turnaround time of every component we install. From standard ductwork to custom-built fittings and architectural sheet metal, our team delivers fabrication that’s as dependable as it is precise.
Streamlined Fabrication. Superior Results.
By handling all sheet metal fabrication in-house, we eliminate third-party delays, reduce errors, and maintain complete oversight of your project’s critical air handling infrastructure. Our state-of-the-art fabrication shop is equipped with CNC-controlled machines and powered by a highly experienced team of union-certified fabricators.
We work with a variety of materials, including:
