Commercial Steel Treating Corp. was founded by Ralph Hoensheid in 1927. The company was originally established to service the emerging automotive market. Commercial Steel Treating experienced rapid growth during the war years and quickly became a trusted and dependable heat-treat source in the metropolitan Detroit, Mich., area.

Commercial Steel Treating has seen many changes throughout its 85 years of existence, but the same performance and integrity that started the business is alive and well. The company continues to be managed by the Hoensheid family – now in its third generation.
 The current processing capabilities of Commercial Steel Treating include:

  • Age hardening
  • Carbonitriding
  • Carburizing
  • Ferritic nitrocarburizing
  • Gas nitriding
  • Induction hardening
  • Neutral hardening
  • Normalizing
  • Solution treating
  • Stress relieving

 With various types of processing equipment in its 150,000-square-foot facility, Commercial Steel Treating has grown into a high-volume fastener and small stamping heat-treat facility. With approximately 65 employees, this 24/7 operation services the automotive, aerospace, military, agriculture, mining and heavy-truck industries. In addition, Commercial Steel Treating is a direct supplier to domestic OEMs. The company currently holds ISO 9001:2008 registration, A2LA laboratory accreditation and is Nadcap accredited for the processing of aerospace products.

The current capacity for continuous belt processing is 500,000 pounds per day. The purchase of a third Can-Eng mesh-belt furnace has recently been approved and will be operational by March 2013. Commercial Steel Treating boasts five Surface Combustion batch furnaces that specialize in deep-case carburizing applications. The company also offers induction hardening of fastener tips.

Commercial Steel Treating owns and operates Curtis Metal Finishing Co., which was established in 1962 and has locations in Sterling Heights, Mich., and Machesney Park, Ill. The Curtis locations are high-volume fastener and small stamping processing facilities that specialize in the improvement of product life through various paint systems. In 2009, Commercial Steel Treating answered customers’ requests for heat-treatment services in Illinois and opened Curtis Thermal Processing. This facility is dedicated to the neutral hardening of fastener products. It does so with two Can-Eng mesh-belt continuous furnaces that can produce 250,000 pounds per day.

With more than 85 years of heat-treating and 50 years of coating experience, the combination of Commercial Steel Treating and Curtis has grown into one of the leading metal-processing suppliers in the country. The company will continue to invest in the latest technology with respect to equipment and processes in an effort to be around for another 85 years.
