Here are some key characteristics and features of CD grade structural plywood:

1. Strength: CD grade plywood is manufactured to meet specific strength and performance criteria, making it suitable for load-bearing applications such as framing, sheathing, and subflooring.
2. Grading: CD grade plywood is typically graded for quality and appearance. The grading can vary, but it often includes designations like “C-D,” “CDX,” or “CD Exposure 1.” These designations indicate the quality of the face and back veneers, with “C” representing a lower grade and “D” indicating a lower grade for the back side. CDX, for example, is commonly used for exterior sheathing.
3. Versatility: CD grade plywood is versatile and can be used in a wide range of construction applications, including roofs, walls, floors, and even concrete formwork.
4. Moisture Resistance: Depending on the specific grade, CD grade plywood may have varying degrees of moisture resistance. Some variants are suitable for use in exterior or damp environments.
5. Uniform Thickness: CD grade plywood is manufactured to have a uniform thickness, which is essential for structural stability and precision in construction.
6. Ease of Workability: While primarily designed for structural purposes, CD grade plywood is also relatively easy to cut, shape, and work with, which is beneficial for construction projects.
7. Cost-Effective: It provides a cost-effective solution for many construction applications, offering a balance between performance and affordability.
