Meet the Brand→GSW Brand Benefits
The GSW name has stood for quality pressure treated pine for over 50 years.
While much of the process used to pressure treat southern yellow pine is a trade secret, every board is tested and backed to perform against rot, decay, and the elements.
Long-Term Protection
Our treatment process drives a waterborne preservative deep into the structure of the wood — guarding against rot, fungal decay, and termite attack across decking, fence, posts, rails, and more.
Environmentally Friendly
A wide array of responsibly treated pine and materials, including kiln-dried-after-treatment (KDAT) products built for a variety of outdoor conditions.
Commercial & Industrial
Specialty products suited to commercial and industrial applications, engineered to hold up in the environments they're built to withstand.
