Jimmy DePetris is also responsible for our Fabrication & Specialty Metals Department. This department includes all metal fabrication from gauge material to plate. Our materials include carbon steel, aluminum, stainless steel and copper. We use the latest technology in CNC high definition plasma cutting.

Jimmy has over 12 years of specialty metal experience (using CNC cutting equipment) and over 25 years of metal fabrication experience.


Our goal with our Construction Department is to complete every project in a safe and timely manner. We use in-house employees, which allows us to carefully time-manage our work force and meet challenging demands for each and every project.

Thermodyne Services understands that for the general contractors we work with to be successful, they must use successful, team-oriented subcontractors. You will find at Thermodyne Services, we hold ourselves to high quality standards and prompt completion of projects, and this does not end when the project is finished. We often continue providing service and maintenance to many property managers and/or building owners after installation. To view our various projects, click here.
