Stack Heat Treaters was opened on January 9, 1984. In 1995 our name was changed to Stack Metallurgical Services Inc., We started out with a couple of atmosphere furnaces and companion draws. Since then, we have grown into the most versatile provider of heat treating services in the Pacific Northwest.

Building on a foundation of Quality, Service and Competitive pricing, Stack has long sought to present to Its customers an attitude of trust and reliability with regards to the processing and handling of their material. This attitude is maintained by having all personnel consider themselves Customer Service Representatives, regardless of position or level of responsibility within the company. Our goal has always been to give the Customer more than they expect at a competitive price.
