5 Steps to Completion of Your Stacks
We design your large diameter, HRSG, bypass, and exhaust stacks to meet standards, as required.
You review our over-dimensional stack design before we begin fabrication.
Steel Stack fabrications are inspected by our in-house Quality Assurance, Certified Welding Inspectors, and/or third-party inspection as our clients’ specifications may require.
We conduct any customized testing that you may require, then blast, coat, passivate, and ship your stack to your facility anywhere in the continental U.S. or overseas.
