Pressure Treated Lumber Supplies

Pressure treated lumber helps to protect your lumber against insects, fungi, and moisture. A liquid chemical preservative is applied to the wood before being placed into a pressure chamber. During this process, the chemical is absorbed into the wood fibers. This allows wood that is typically prone damage, such as softwood, to become a durable material.

The method is to place the lumber into an airless holding tank. Wood preservatives are forced into the tank under high pressure. This presses the preservatives into the core of the wood. Instead of breaking down the wood, it adds strength and protection against fungus and insects. This makes it an ideal choice for playground equipment and jungle gyms.

Pressure treated lumber can be used for decks, patios and fences without being easily damaged. Otherwise, you run the risk of only getting a couple of years from your materials before being ruined by moisture. In fact, it can last for more than 40 years.

The Benefits of Pressure Treated Lumber in Toronto:

Lumber is made of the organic byproduct from trees. The rate at which wood deteriorates depends on the conditions and environment it is in. Winters in Toronto can wreak havoc on outdoor wooden furniture and structures, such as patios and decks. The wet and cold climate, mixed with the moisture of Lake Ontario nearby, makes the issues even worse.

To combat these conditions, and slow down deterioration and ensure longevity, lumber is pressure treated. The process cures the wood, adding vitality to it, and making it more impervious to the elements that Toronto throws at it. However, this enhancement makes pressure treated lumber more expensive.


In short, you can sum up the benefits of pressure treated wood to:

  • Affordable
  • Bug proof
  • Durable
  • Strong
  • Bacteria resistant
  • Long lasting
  • Scratch resistant
  • Resilient to harsh weather elements

That said, there are some disadvantages and risks associated to pressure treated plywood.

Chemically treated wood is not healthy – The chemical absorbed into the wood is a toxic copper-based liquid that is dangerous to people and pets. The copper element is the reason for its resistance to bacteria, fungi and insects.

Pressure treated lumber is not good for the environment – It does not decompose well because of the toxins in the material, making it difficult to dispose of.

Never burn chemically treated wood. If it does catch fire, chemicals hazardous to life and the environment will be released into


Common Uses For Pressure Treated Lumber

Pressure treated wood is commonly used outside, and can be used in swing sets, boardwalks, decks, light posts, residential building foundations, and even picnic tables.

The wood can go through several levels of pressure treating processes. These include interior and exterior use, water (both fresh and salt), and fire. Our professional and knowledgeable staff is available to help you choose which pressure treated lumber is best for you to use in Toronto and the GTA.

You will eventually see signs of weathering, but this does not indicate rot. To keep the wood pristine, you should seal it to keep the original aesthetics.
