Reduce Field Welding Time with Mock-up & Fabrication

With more than 40,000 square feet of combined space, our facilities in Chattanooga, TN, and Charlotte, NC, are outfitted with the latest technology and equipment to pre-fabricate systems and confirm proof of concept, which help reduce field welding time and deliver first-time quality. We mimic field conditions such as limited access and complex configurations to meet any project requirements.
