Swanson Group has acquired Olympic Panel Products LLC, located in Shelton, Washington. Olympic Panel is the largest overlay plywood manufacturer in North America.

Swanson Group plans to relocate the Olympic Panel assets in 2016 to its state-of-the-art facility that will be constructed in Springfield, Oregon. The new facility will continue to produce Olympic-branded products.

“Swanson is building a world-class plywood and veneer manufacturing facility in a location with an excellent workforce and log supply,” says Steve Swanson, President and CEO of Swanson Group. “We have long been impressed with the quality and depth of Olympic’s overlay product line and believe that this acquisition fits perfectly with our goal to become the leading producer of overlay panels in North America.”

From plywood concrete form panels to specialty panels to tongue and grooved Sturd-I-Floor for residential and industrial applications, Swanson Group has the right panel for your specific application.

Swanson Group mills carry the stamp of the American Plywood Association (APA). Our panels are regularly tested to insure their compliance with the APA’s manufacturing specifications.

Swanson Group Doug Fir siding comes in premium and standard grades. It combines the beauty of real saw textured wood with the ease of working with a plywood panel. Sanded plywood is a versatile product that can be used for shelving, cabinets or anywhere a smooth surface is needed. Marine grade plywood is specialty plywood that has the most demanding specifications in the production process.

The panel that made Swanson Group known was our 1⅛” Sturd-I-Floor underlayment, considered to be the best in the industry. This platform, while ideal for sub floors in residential applications, is successfully used in many industrial roles.
