Glasswerks, a Southgate-based glass fabricator, acquired Seattle-based Northwestern Industries Inc.

Terms of the deal were not disclosed, but Glasswerks said the purchase will boost “capacities, distribution, and overall foothold in the glass and glazing industry.”

Northwestern Industries, founded in 1975, is a subsidiary of Japan-based Central Glass Co. Ltd. Northwestern will shutter its 300,000-square-foot manufacturing complex in Seattle and lay off 133 workers while its 100,000-square-foot facility in Yuma, Ariz., with 110 employees will continue operations under the same name and management.

“I’ve long admired the excellent reputation for quality and service that NWI has built in this industry,” Glasswerks President Randy Steinberg said in a statement.

Glasswerks has about 500 employees and annual revenue between $100 million and $150 million, according to the company. It specializes in commercial and heavy-fabricated glass; architectural, tempered and laminated glass; as well as decorative glass.

Glasswerks, founded in 1980, runs facilities in Southgate, Temecula and Carson totaling 700,000 square feet of fabrication space.
