Company History

Thermal One Inc. is the result of merging two companies, Header Heat Treat and Kee Services. Header Heat Treat was established in 1960 performing salt bath heat treating and in 1994 the first Vacuum Furnace was installed. In 1998 all salt baths were shut down and operations were moved to our new state of the art vacuum furnace facility. Kee Services was establish in 1965 and in 1972 installed the first vacuum heat treat furnace in Metro Detroit.
