Pressure Treating Process Information
At Only Fencing, our SPF #2 Appearance Grade lumber has been preserved by pressure-treatment with copper azole to protect it from termite attack and fungal decay.
Our Wood Pressure Treating Process
In the treating process, copper azole penetrates into the wood where it remains for a long time. However, some chemical may migrate from preserved wood into surrounding soil over time and may also be dislodged from the wood surface upon contact with skin. Exposure to copper azole may present certain hazards so please exercise extreme caution when handling the wood.
