Pressure treating is a preservative process that helps plywood stand up to the weather, decay and insects.
Designed so panels fit together quickly and easily. This joint creates a strong and tight connection.
As span rating increases so does performance category. This is because as the supports get further apart, thicker wood is necessary to ensure it will be able to handle the load.

Plywood is a popular choice for residential and light-duty construction and is made from thin sheets of veneer that have been peeled from debarked wood. These thin layers, also called plies, are glued together in alternating, perpendicular directions to create a cross-graining pattern. This pattern results in added strength and stability that resists shrinkage and expansion.
Oriented Strand Board (OSB)
Plywood is an engineered wood from the manufactured boards family, which also includes particle board and oriented strand board (OSB). The types of wood species that are used in engineered plywood include ash, oak, birch, maple, cedar, spruce and pine. Other types of engineered wood include sanded plywood, specialty boards and project panels. The most common uses for plywood include support for floors, walls, roofs and garages in residential construction.
Plywood Features
It’s important to consider plywood features. Pressure treated plywood helps plywood stand up to the weather, decay and insects. The preservative process makes pressure treated plywood last long and is ideal for outdoor projects. Tongue and groove plywood is designed so panels fit together quickly like a puzzle. When used for roofing, plywood panels are covered and protected by a variety of building materials that keep the elements at bay, including roof felt, underlayment, flashing and shingles. When used in flooring, plywood functions as the subfloor that supports hardwoods, tile and carpet floors.
Ratings, Grades & Sizes
Plywood is sold in various ratings, grades and sizes. Make your selection based on the type of project you’re working on. Our plywood buying guide will help you make the right decision. We’ll even deliver your plywood in bulk.
