History

Formed in 1927 by Ralph Hoensheid, Commercial Steel Treating Corporation made its name by supplying quality heat treating on items such as reamers, dies, punches and other various high speed and tool steels. The success of the operation and the emerging automotive industry provided growth into a total of three facilities, all located in the metropolitan Detroit area.

In 1963, Merle Hoensheid (Ralph's son) recognized the automotive demand of different colored fasteners for metric identification and formed Curtis Metal Finishing Company. The plants supply Phosphating, electrodeposition and dip-spin paint systems.

In 1980, the heat treating plants were consolidated into a 150,000 square foot facility located in Madison Heights, Michigan. Today, the Corporation is led by Scott Hoensheid (Merle's son). Commercial and Curtis continue to be a leader in the automotive industry and have achieved QS9000/IS09002 registration and A2LA laboratory accreditation. The same QUALITY ethic that began in 1927 is evident today throughout all the operations.
