Pressure treated decking is the most commonly used decking material in the southeastern market. This is largely due to its low cost compared to composite or hardwood options. Pressure treated decking is available in 5/4x 6” (1’ thick) and 2×6 (1.5” thick) and in a variety of grade ranges that include everything from “standard” grades to “vertical grain” grades.
Pressure treated decking can be stained using a variety of penetrating stains designed for exterior decks. Although some sources recommend waiting weeks or months to stain a deck allowing for it to “cure out”, it’s our opinion that the staining process should be done right after the deck is completed. This avoids the weathering, swelling, and contracting that occurs if a stain / sealant is not applied.
Pressure treated decking retains moisture after the treatment process occurs. As a result shrinkage to varying degrees can occur after installation.
KDAT (Kiln dried after treatment) is a process that’s applied to pressure treated decking that provides for a more stable wood decking option. Because the material is dried in a kiln after it’s treated, it’s less likely to shrink after installation providing for a more stable product.
Pressure treated boards typically come in 12’ and 16’ lengths and can be installed with a variety of fasteners. (Consult your Metro Building Products representative for more information)
