Bold Black End Tags

For projects that are built to last, ProWood® professional-grade treated lumber offers a wide selection of grades to suit virtually any outdoor project. ProWood pressure-treated lumber is perfect for decks, exposed structures, sill plates, and other applications. What’s more, ProWood MCA-treated (micronized copper azole) wood is more natural looking, less corrosive to fasteners and looks good longer than many other brands.

Being able to understand the capabilities, and the limits, of treated lumber can ensure projects and structures are built to last. Each color bar on the end tag represents a treatment option: Light Duty, Above Ground, Ground Contact, Critical Structure, and Borate. Generally, manufacturers and dealers are embracing ground contact/general use treated lumber to eliminate confusion and to ensure their customers are covered.

ProWood’s focus is on educating homeowners and professionals to not only make the right decision, but to understand the reason behind it. The most common treatment options available are ProWood Light Duty, ProWood Above Ground, ProWood Ground Contact, and ProWood Critical Structure.


ProWood Light Duty

Represented by a white bar on the end tag, this type of pressure-treated lumber is designed for non-structural projects that are easily replaced and maintained. The recommended applications for this treatment option include fence pickets, lattice, and landscape timbers. This option comes with a One-Year Limited Warranty (in proper application).

ProWood Above Ground (UC3B)

Represented by a gray bar on the end tag: Above-Ground treated lumber is best suited for elements that are easily replaced, maintained, and installed at least six inches above the ground. The recommended applications include railings and balusters but not for deck joists, beams, or near-ground uses. And ProWood Above-Ground lumber is backed by a Lifetime Limited Warranty against rot, fungal decay, and termites (in proper application).

ProWood Ground Contact (UC4A)

Represented by a green bar on the end tag: Ground Contact lumber is our most used general-purpose treated choice for above-ground, ground-level, and freshwater applications. This treatment option is required for elements critical to the integrity of the structure and difficult to replace such as ledgers, beams, joists, and posts. Ground Contact treated lumber is recommended for projects with inadequate ventilation, frequent moisture, or in contact with the ground (like garden boxes). ProWood Ground Contact is backed by a Lifetime Limited Warranty against rot, fungal decay, and termites (in proper application).

Ground contact/general use treated lumber should be used if any of the following apply to the project:

  • The lumber is difficult to replace or maintain.
  • The lumber is critical to the integrity of the structure.
  • Lumber is 6 inches or less from the ground – or touching the ground.
  • The lumber will be subject to inadequate ventilation.
  • The lumber will be exposed to frequent or prolonged moisture.
  • Examples include: Deck joists, beams, ledger boards, posts, stair stringers, and certain deck board installations

ProWood Critical Structure (UC4B)

Represented by a dark green bar on the end tag, Critical Structure is best suited for projects in severe environments, such as horticultural sites, critical components, and climates with a high potential for deterioration. This type of pressure-treated lumber is ideal for permanent wood foundations, building poles, decking, or above-tidal zone structural components in piers or docks. ProWood Critical Structure is backed by a Lifetime Limited Warranty against rot, fungal decay, and termites (in proper application).

Kiln Dried – KDAT

ProWood Kiln Dried After Treatment (KDAT) features high-quality MCA treatment for additional dependability. This solution helps to reduce shrinking and warping, making it the best choice for your next outdoor building project. ProWood KDAT is reliable and stable for lifetime protection against termites and decay (in proper application).

Color-Treated Lumber

ProWood color-treated lumber is a great option in markets that want the natural look and beauty of cedar or redwood but desire the lasting benefits of pressure-treated Southern Yellow Pine. It is a great sustainable choice as the color is infused throughout the board during treatment. This is a go-to-choice for many outdoor building projects that use standard pressure-treated lumber. Contractors save time on site by eliminating the annual chore of staining a deck, railing, fence, or pergola. ProWood’s in-solution colorant penetrates the wood deep beyond the surface.

SCS Certified: Environmentally Preferable Status

ProWood is SCS certified; our MCA (Micronized Copper Azole) treated lumber has received the Environmentally Preferable Product (EPP) status and the National Green Building Standard (NGBS) Green Certification. What does this mean for professionals and DIYers? ProWood lumber is safer for pets, children, and the earth below them than other brands.

Testing and Warranties

Other leading brands rely on internal testing, while ProWood uses independent, third-party testing agencies. Every charge of ProWood dimensional lumber, decking, and timbers produced are tested for penetration and retention of preservatives to meet the stringent guidelines of American Wood Protection Association (AWPA.com). While others may deliver an inconsistent product, ProWood proudly distributes dependable, unvarying lumber products. Additionally, there are many lifetime-limited warranties available for treated lumber; however, it is important to understand the details of those warranties — especially the definition of the term “limited” (as some may only warrant treated lumber used in Above Ground/Light Duty applications) and who backs your warranty. ProWood is unique in that they back the warranty.

ProWood’s industry-leading Lifetime Limited Warranty refers to coverage for Ground Contact, Above Ground Contact, Critical Structure, and Borate, in proper applications. Dealers feel more confident sending customers home with ProWood knowing they are protected by a trusted brand. Not only that, but ProWood treated lumber is treated to a higher standard and meticulously inspected by third party to ensure code compliance.

With pressure-treated lumber remaining the dominant material used for decks, it’s important for dealers and contractors to be educated about the differences in treated lumber — both for deciding which treated lumber to stock, and to be a source of education and guidance for homeowners, DIYers and building professionals alike. The right treated lumber used in the appropriate application will result in a beautiful, safe deck or outdoor structure that will last for years.
