Rainier Plank is a line of engineered lumber and decking made by Defiance
Forest Products for interior millwork and exterior trim and facia. We currently manufacture clear Douglas Fir and Western Red Cedar.
These products are made with a Douglas Fir core, waterproof exterior grade glue, and the highest grade veneers in the world.
The Rainier Plank line offers clear advantages over solid lumber:
• Costs significantly less than solid lumber
• Higher grade
• Exterior grade glue
• Extends the resource
• Engineered for straightness and stability
