What's "YellaWood," Anyway? YellaWood, made by Great Southern Wood Preseving, is a unique, treated lumber that's protected against rot, fungal and termite decay. For nearly 40 years, Great Southern Wood has provided this pressure-treated lumber around the country. They accept only the highest quality yellow pine, then put it through an extensive preserving process that includes a copper-based solution forced deeply into the cellular structure of the wood. This is what protects the wood from rot and attack by insects. YellaWood is certified as an Environmentally Preferable Product.
