We all are aware of how versatile are plywood. From dockyards to TV cabinets, from modular kitchens to temporary support in construction, we can spot them everywhere. While a single type of plywood is already quite versatile, they are graded according to quality as there is no one-size-fits-all for plywood. Grades of plywood determine the suitability of its application. Plywood manufacturers use standard grading to suit specific applications. In this blog, we will learn about these grades, and their common applications so that they help you make well-informed decisions.
Understanding Plywood Grades
Plywood manufacturers grade them based on the veneer’s quality, moisture resistance, and imperfections appearance. The application of each grade of plywood depends upon requirements, maintenance, appearance, and finished look. Here is the general classification of plywood grades:
1. A Grade Plywood
This is the highest quality plywood with a smooth, sanded surface without knots, patches, or any defects. Ideal for visible applications since plywood also serves aesthetic purposes beyond its functionality. It is suitable for cabinet doors, high-end furniture fronts, and decorative wall panels.
2. B Grade Plywood
B-grade plywood gives a flawless look with minor defects like grain variations, patches, and blemishes. It is less expensive than an A grade, but still has a smooth surface, offering a good balance between cost and surface finish. Suitable for surfaces that can be painted, interior panels, cabinetry, and shelving.
3. C Grade Plywood
The defects in C-grade plywood are noticeable, hence they are not used for aesthetic purposes. It may contain knots and cracks that require patchwork and polishing. It is not sanded, and less expensive than A and B plywood. Suitable for structural applications for subflooring, roofing, and construction.
4. D Grade Plywood
D-grade plywood is used for strength rather than appearance. The visible knots, splits, and blemishes need not be fixed as they are used for temporary construction structures like shuttering plywood, packing cra6tes, and industrial applications.
Moisture- Resistant Plywood Grades
Apart from the above standards, plywood is also categorized according to moisture resistance, and these categories have quite popular applications:
• MR (Moisture Resistant): Withstands moderate levels of moisture and is suitable for interior panels, indoor furniture, and doors in dry areas.
• BWR (Boiling Water Proof): Provides a high level of water resistance, considered fully waterproof and therefore suitable for marine applications. E.g.- boat buildings, outdoor structures, areas with heavy rain or water splashing, and shower enclosures.
• BWR (Boiling Water Resistant): Ideal for highly humid environments as these are highly resistant to moisture and can tolerate exposure to boiling water. Used in kitchen cabinets, bathroom vanities, and outdoor furniture.
Conclusion
The grading of plywood is the determining factor of its application. However, it is not the only factor as the core composition, types of adhesives, and face of the veneer also are crucial differentiators in plywood making.
