MCA lumber preservatives are registered with the EPA and provide long-lasting, clean-to-the-touch protection against rot, fungal decay, and termite attack. This treated wood has no objectionable odor and can be easily painted or stained. A solution including water and certain chemicals is added under pressure to force the solution into the wood. The solution is then vacuumed out again and the treated wood is left to dry.
Depending on the application, treated wood can easily last for decades. Pressure treated wood is lumber that's been infused with a solution of water and chemicals to make it resistant to rot and insects. The chemicals used to treat the pressure treated wood sold at McCoy’s include copper, a natural element, and a small amount of tebuconazole, a fungicide. It can safely be used around animals and plants, so it's great for raised garden beds. Additionally, the pressure treated wood at McCoy's is not only approved for outdoor projects on land, it's also approved for use in fresh water, such as for docks.

Fortunately, ALL 2x6 and greater dimensional pine lumber at McCoy’s is treated for Ground Contact. This means it has almost twice the concentration of preservatives as Above Ground rated treated wood, ensuring the lumber in your project will be durable and long-lasting. Lumber that’s pressure treated for Ground Contact is anything that is within 6’’ of the ground. Any application this close to the ground or touching the ground has a risk of prolonged exposure to ground moisture, fungus, and insects, so it requires a higher resistance to the elements and pests. Our trusted delivery services can save your company time and money. Ground Contact lumber should be used for decking, posts, stringers, beams, ledgers, and joists.
This type of treated wood is used in places with good air circulation, water drainage, and limited contact with plants or leaf litter. Spindles, railings, and balusters are examples of places where Above Ground Rated Lumber is a good choice. And if you’re nervous about buying treated wood that’s been infused with chemicals, worry not. Micronized Copper Azole is the recipient of an Environmentally Preferred Product designation from Scientific Certification Systems.
Above Ground Rated Pressure Treated Wood
Our treated lumber products are pressure treated to prevent decay and rot in situations where the lumber is exposed to the elements. Yellow pine and Douglas fir are among the most common types of wood used in this process. Other natural woods like teak, mahogany, and red cedar, are naturally rot- and insect-resistant and don’t need to be treated.
Providing quality and sustainable building materials, a strong product mix and selections. Check the label on the end of the board -- the higher the chemical retention level, the more rot-resistant the board. You can learn more about Micronized Copper Azole from this resource. The end tag will also tell you who manufactured the lumber and any warranty terms.

Pressure treated wood is one of the best options for outdoor projects. Yet, even within this type there isn't a one-size-fits-all solution. When planning a build, you’ll need to determine what type of treated lumber to buy and where to use it. We'll help you figure out what you need — and whether pressure treated wood is right for your project.
However, they tend to be far more expensive than pressure treated wood. You may have heard that pressure treated lumber is preserved with arsenic, a poison that can leach out into your environment. However, at McCoy’s, the pressure treated lumber is high quality and treated with an environmentally preferred MCA preservative . Lumber stamped Above Ground Use should be used at least 6” above the ground.
