Plywood is a versatile building material, but it comes in different grades, primarily classified as structural and non-structural. Understanding the differences between these two types is crucial for selecting the right plywood for specific applications.
This type is engineered for strength and rigidity, making it suitable for heavy-duty applications such as construction, roofing, and flooring. It can bear significant loads and is designed to withstand environmental stresses like moisture and temperature changes due to its high-quality adhesive bonds (e.g., A-bond or WBP glue) used during manufacturing.
In contrast, non-structural plywood is intended for lighter applications, such as furniture making or interior cladding. It typically uses lower-grade adhesives (C or D-bond), which do not provide the same level of strength or moisture resistance as structural plywood.
Often features a denser core with more layers (plies), enhancing its stability and durability over time. The inner layers may be made from stronger wood species, contributing to its overall strength.
Generally has fewer layers and may be made from softer woods, resulting in a more flexible product that is easier to work with for non-load-bearing applications.

Typically has lower-grade face veneers since it is often used in applications where the appearance is not a priority. The focus is on performance rather than aesthetics.
Often features higher-grade veneers that are visually appealing, making it suitable for projects where appearance matters. This type of plywood can be finished or painted to enhance its aesthetic value.
Generally, structural plywood tends to be more expensive due to the additional layers and higher-quality materials used in its production. Non-structural plywood can be a cost-effective alternative for projects that do not require high strength or durability.
Choosing between structural and non-structural plywood depends on the specific requirements of your project. For load-bearing applications where strength and durability are critical, structural plywood is the preferred choice. Conversely, for decorative or lighter applications, non-structural plywood offers flexibility and cost savings without compromising on visual appeal.
