What is the difference between SDX and plywood?

SDX (Structural Drywall) is a type of engineered wood product designed specifically for use in construction, providing structural support in walls and ceilings. Plywood, on the other hand, is made by gluing together thin layers of wood veneer, offering versatility for various applications, including furniture and flooring. While both materials are used in building, SDX focuses on structural integrity, whereas plywood is more about flexibility and aesthetic appeal. Additionally, SDX typically has a higher strength-to-weight ratio compared to standard plywood.
