The Lockformer Company was founded.
Year After Year Improving Duct Fabrication Productivity for YOU.
We have been in the HVAC sheet metal, duct fabrication industry for 70+ years and have specific plans for the future. In that time we have worked successfully with thousands of duct shops. We have more than accomplished our mission of reducing the cost of sheet metal duct fabrication. Imagine duct shop life without the Pittsburgh, the Welty Way / Fabriduct Coil Line, the rolled on TDC and TDF flanges, the Vulcan Cutting System, the Whisper-loc or the Cornermatic. Imagine duct shop life without our continuous improvements and other innovations.
We are proud of our innovative history and the legacy we have created. Have a look below at several milestones in the history of our company.
