How is plywood graded?

Plywood is graded primarily based on its quality, appearance, and defect characteristics. This grading system takes into account various factors, such as the presence of knots, grain patterns, and surface finish, which affect both the aesthetic and structural properties of the plywood. Higher grades will have fewer defects and a more uniform appearance, making them suitable for applications where the finish is visible, such as cabinetry and furniture. Lower-grade plywood may contain more knots and surface imperfections, making it ideal for structural applications or for use where the surface won’t be seen. The grading system allows consumers and builders to select the appropriate type of plywood for their specific needs based on these characteristics.
