Custom & Specialty Metals

MacMiller specializes in advanced modular prefabrication, expertly building large-scale equipment skids and mechanical piping racks. Our proficiency allows us to construct entire mechanical rooms off-site and install them in place on-site in as little as a single day, significantly reducing project timelines and on-site disruption.

Our fabrication shop specializes in a wide range of plumbing and pipe fitting solutions. We handle everything from multi-trade racks (MTRs) to prefabricated risers and entire bathroom wall assemblies, constantly finding innovative ways to leverage the benefits of off-site fabrication. To maximize efficiency and quality, our 3D BIM/Detailing teams send “spool” packets of complex piping systems. We then break them into modular sections that are built in our shop and sent to the site for seamless installation, ensuring your project stays on schedule.

We go beyond standard mechanical systems to deliver exceptional, high-end architectural and specialty metal fabrications. Our skilled craftsmen and in-house capabilities allow us to tackle unique, complex project from cleanroom-grade stainless steel components to one-of-a-kind aesthetic pieces.
