About Us

Patriot Custom Metal Fabrication, was officially founded in 2020 as an OnPower, Inc. sister company. We offer turnkey solutions with inhouse fabrication, welding, light machining and assembly production.

Our organization, originally founded in 2001 by Larry D. Davis, has almost 50 years of leadership and engineering experience fabricating and packaging custom engineering solutions for power generation and marine propulsion systems. Patriot Custom Metal Fabrication has been able to tap in to the vast experience and resources acquired from their previous work under U.S. Turbine Corporation (’84-’97) and later Rolls-Royce Energy Systems (’97-’01) to develop and deliver reliable designs that encompass rotating equipment, controls, and support systems.

OnPower, Inc. houses an assembly and fabrication warehouse of 75,000 SF, with an office space for design and engineering of 8,250 SF. The facility is capable of all welding and light machining needs and houses a separate clean room used for all electrical and controls assembly. On-site we have a 10 MW variable resistive load bank and a 400-kW mobile APU for any testing and black start simulation needs. OnPower, Inc's 2-acre test pad utilizes an extensive power control and data acquisition room for testing with the ability to test both natural gas and liquid fuel.
We are ISO 9001:2015 certified as a manufacturing organization and scope of certification covers our capabilities.
