Pressure treated decks from Atlanta Decking offer increased protection from moisture, insects and mold for up to 20 years. Our high quality decks are made with premium grade pressure-treated boards that have fewer knots and straighter grain. This gives the deck a smooth and cohesive look. We also offer kiln-dried and treated (KDAT) wood that is more resistant to warping and splitting. We use boards from southern yellow pine that offer a beautiful natural wood appearance.
