PRESSURE TREATED 3/4‘‘ CD

Description

CD34 treated plywood is a type of structural plywood that has been pressure-treated with preservatives to improve its resistance to moisture, decay, and insect damage. The CD grading refers to the quality of the veneer faces, where one side is C grade (relatively smooth with minor defects) and the other is D grade (rougher with visible knots and repairs). The 12 designation typically relates to the treatment standard or hazard class, indicating suitability for certain exposure conditions, such as outdoor or ground-contact use. This makes CD34 treated plywood a practical choice for construction projects like subflooring, decking bases, and exterior structures where durability and longevity are important.
