We are noted for our major process work. Depending on the requirements of the project and the industry, we use stainless steel, glass, fiberglass, copper, PVC, Teflon lined piping systems, or whatever piping material is most appropriate for the project at hand.

Piping fabrication is a key component of Armistead’s project management philosophy, and our project teams employ prefabrication whenever possible on all jobs. It not only offers savings to our customers, but also provides us with a competitive edge and scheduling advantages.

We provide 3D design assist coordination with a collaborative approach that results in higher quality, functionality and cost savings. Our design teams include P.E.’s, Licensed Master Plumbers and HVACR specialists skilled at applying virtual design, prefabrication and value engineering methods to meet the mechanical needs of any project.
