The YellaWood® brand has stood for quality pressure-treated pine for over 40 years. Our pressure treatment process forces a waterborne preservative deep into the structure of the wood, providing long-term protection against rot, fungal decay, and termite attack. The process has been applied to many types of pressure-treated wood, such as decking boards, picket fence, and split fence materials, pressure-treated plywood, posts & rails and other materials, just to name a few.
