Completed in early 2015, General Sheet Metal’s (GSM) expanded Sheet Metal Fabrication Shop has over 35,000 square feet of production space to create a wide variety of products. From standard sheet metal fittings and everyday items to complex systems, our shop has seen it all.
We are a Sheet Metal and Air Conditioning Contractor’s National Association (SMACNA) certified shop, meaning our fabricated ductwork has been reviewed and received a certified stamp of approval, thus meeting or exceeding SMACNA standards.
Before leaving the shop, all finished products go through a strict quality control check to verify they meet the proper tolerances and project specifications, as even minor variations can cause unnecessary and costly delays in the field.
At GSM, we provide:
- Commercial and industrial round, oval, rectangular, and spiral ducting
- Welded curbs, curb adapters, hoods, equipment stands, hangers, and shaft duct supports
- Certified welders for structural projects and grease ducting
- Curb flashings, angle, Z-metal, seismic brackets, plenum walls, and other custom break shapes for materials 26ga – ¼ inch plate
- Custom fab of chimney stacks/caps, louvers, filler racks, water tanks, and countertops
At GSM we take the quality of our products seriously and strive to provide the best value to our customers. We know that circumstances change on an hourly basis and are committed to helping you meet your needs whether it’s a quick turnaround or being available for fabrication during off-hours. We are your fabricator of choice!

“I wanted to thank you for the work you did on our varnish take fume extraction project. We got the exhaust fan powered up and did an experiment. With the VFD seat as low as 40%, we were able to capture 100% of the fog around the entire perimeter, it worked great!"

I wanted to express my appreciation for the outstanding efforts made by the contractor and OHSU West Campus in making not just one, but two difficult cutovers happened with such great success. Rarely have I seen groups come together this well and produce an outcome of this quality under the tight time frames as we had on these two projects. From what I heard, this also occurred with minimal disruption and inconvenience to the building occupants. To me this speaks as much to the quality of the individuals as it does to their skills. I would welcome the opportunity to with work with all of these people again, although I’m sure we’d all prefer that it were under more normal conditions. So, thanks to all those “weekend warriors’ who gave up their weekends to make this all happen.

Your employee was here last week to dismantle our Dust Collection System did an AWESOME job! We were very happy with him; he was courteous and careful. He went the extra mile, didn’t damage anything- machines or cabinets that were close by where he was working, even swept up after the job was done! It speaks very well of your company to have such an asset representing General Sheet Metal.

I want to thank you both again for a seamless install, the care and communication you took through the project was fantastic. I was very impressed with Phil’s coordination and site management of the project. Being new to the area, and not knowing subcontractors, you made me feel at ease through.

I really appreciate all the excellent work you and GSM have provided us this year. NIS in particular is leaps and bounds ahead of where we started the year.

Your team was flawless in execution. Very impressive. The fan is on a VFD.

It is with great pleasure that I write this letter of recommendation. Working with you and your staff on the Gateway Discovery Park Project was a refreshing experience. Your collaboration, attention to detail and craftsmanship in completing the complex scope was evident in the final product. You approached the project with a teamwork mindset and your problem-solving skills helped deliver solutions that were mutually beneficial to GSM and City of Portland Parks. I write this letter without hesitancy in recommending General Sheet Metal on future projects. Should any of your prospective clients wish to talk with me first hand I can be reached at the contact information below. Your expertise was critical to the successful outcome on this project and I hope we have an opportunity to work together again.”
