How is plywood classified based on its grades?

Plywood is classified based on its grades primarily as A, B, C, and D, which indicate the quality of the wood and the surface finish. This grading system helps consumers understand the characteristics of the plywood they are purchasing.

Grade A plywood is of the highest quality, featuring a smooth surface with few imperfections; it is often used for visible surfaces in furniture and cabinetry. Grade B plywood may have some minor defects but is still suitable for high-quality applications. Grades C and D have increasing levels of imperfections, with C being usable for construction where appearance is less critical, while D grade plywood contains more visible defects and is typically used in construction or where aesthetics are not a concern.

This grading system is essential for ensuring that builders and consumers can select the right type of plywood for their specific needs, based on the balance of quality, durability, and appearance.
