Exotic Metals Forming, an aerospace supplier based in Kent, will build a second plant with up to 150 workers close to Spokane International Airport, the company announced Thursday.

The company purchased the 57-acre site from the airport and plans to build a new 150,000-square-foot aerospace manufacturing plant. The property is in the city of Airway Heights.

In Kent, Exotic employs about 900 people. It designs and manufactures complex, high-temperature, high-strength sheet metal components for commercial and military aircraft, including tubes and ducting as well as door seals and thresholds.

Customers include both Boeing and the jet-maker’s first-tier suppliers, such as United Technologies.

Exotic said it conducted an extensive site search over 18 months and considered a number of sites in other states before choosing eastern Washington.

Doug Gines, chief operating officer at Exotic, praised the “pro-business approach” of the Airway Heights city administration.

The city pledged funds to extend sewer service to the site, add traffic capacity at a nearby road intersection, and to fast-track the permitting process.
