Production Fabrication

While many mechanical contractors talk about their fabrication shop, Dunbar has taken this concept to an entirely new level through manufacturing optimization.

We started by asking “How can you build in a manufacturing way something which you are only going to create once? How can you create highly customized assemblies with a focus on throughput, raw materials, and process optimization? How can it all be completed and ready to deliver to each job site on a just-in-time basis?”

The impact has been a tremendous time, money, and frustration savings for our clients. Dunbar’s Production Fabrication focuses not on adding fittings but on racking and providing assemblies that are installation ready, with tolerances of +/- 1/16 of an inch. Through our manufacturing fabrication services, Dunbar Inc. has THE most efficient and effective building process to provide the most benefits for your projects.

Dunbar Inc.’s Virtual Construction services, combined with the production efficiencies of our fabrication facility, truly are services you won’t find anywhere else. Check out what this industrial client had to say about Dunbar’s way of doing things:

“A lot of people here are impressed with what we were able to do in a little bit of real estate. Space-wise there wasn’t a lot of room and we got a lot in there. It’s been interesting because people here don’t really understand how it’s getting done. They don’t see people at the site for days and then, all of a sudden, the job is half done. It’s a different way of doing it and they don’t totally understand how it’s getting done.”

Our isolated stainless area for aseptic projects ensures the highest quality for our special customers. Complete with its own filtered air system and dedicated equipment, Dunbar’s food-grade stainless area provides peace of mind for all of our food and beverage clients who require sterility throughout their operations.

Dunbar Inc. fabricates solutions to precise tolerance through:

  • Virtual Construction to efficiently and accurately determine materials needs and cut lengths.
  • Automated equipment that provides true manufacturing efficiencies
  • Customized material handling labor-saving devices
  • Automated, state-of-the-industry MIG, TIG and submerged arc welding processes
  • Labor and material savings tee pulling processes
  • Vic-Eze equipment for precise and automated pipe grooving
  • Completely clean assemblies guaranteed through our segregated stainless area
  • A quality assurance process to ensure accuracy throughout the manufacturing process.

We offer flexible fabrication services as part of our operations. Dunbar Inc. has gone to great lengths to design our fabrication facility with manufacturing efficiencies for through-put, effectiveness, and optimized workflow. We operate as a manufacturing plant to give you the customized assemblies you need when you need them.

Dunbar carries our focus on completing everything possible BEFORE sending equipment and fixtures to your location by prepping and pre-assembling items that can’t be fabricated such as installing faucets and all connecting piping in sinks, tubs, and toilets. We then “kit” these items, adding all ancillary pieces and removing all extra packaging materials, etc. This ensures the quickest completion for your project and sets our field force up for success by ensuring the most productive use of their time.

Dunbar’s manufacturing plant is ISO 9001:2015 Certified. Dunbar Inc. is ASME certified per section IX with the following stamps: “R,” “U” and “PP” for vessels. We also have an in-house weld inspector (CWI) who is certified by the American Welding Society and the American Society of Nondestructive Testing for Level II Visual Testing.


We use a flexible approach, tailored to customer needs.
