Grades of Plywood
Because of its robustness and inexpensive cost, plywood is a popular engineered wood in many home building projects. Understanding the various grades of plywood is crucial for selecting the finest material for the job.
Plywood Grades: Softwood
Each veneer in softwood plywood comprises two grades, one for the “face” veneer and one for the “back” veneer. Plywood veneer comes in four grades: A, B, C, and D.
A-grade plywood is the best available. While it may cost more, the time savings for tasks that will be visible to the naked eye may be worth it. This plywood is smooth and simple to paint.
Minor faults in B-grade plywood are common and may necessitate minor repairs. It’s a little rougher.
C-grade plywood includes larger defects and knots that can measure up to 1.5 inches in diameter.
D-grade Large defects and knots up to 2.5 inches in diameter are possible in plywood. This is the most affordable grade of plywood veneer.
The first letter denotes the grade of the plywood’s face, while the second denotes the grade of the plywood’s back. As a result, “AB” plywood has an A-grade face veneer and a B-grade back sheet.
Plywood Grades: Hardwood
The grading system for hardwood plywood is unique. Face veneer, like softwood, is designated by letters, with A being the greatest grade and D being the lowest. Backs, on the other hand, have a different standard: 1 is the best and 4 is the worst.
The highest grade plywood is A1, while the lowest quality (but most cost-effective) plywood is D4.
Which Plywood Grade Is Best For My Project?
This is dependent on your project. A1, A2, B1, or B2 are suitable alternatives if both sides of the plywood will be seen. If the back will not be seen, A4 or B4 will suffice.
If you want a clear finish, A1 or A2 is probably the best option. If the plywood will be painted, classes B and below are appropriate for the faces, and grades 3 and lower are appropriate for the backs.
Are you thinking about using plywood for an outdoor project like a deck, roofing material, or a shed? Make certain that the material is moisture resistant. If the plywood has an X at the end, it can resist some moisture exposure.
Marine grade plywood is offered for constructions such as cisterns and boat hulls that will be exposed to water for an extended period of time.
Although this grading system might be a good starting point for balancing cost and quality, it is always a good idea to inspect plywood items in person to ensure the grain pattern, flatness, and edges suit your project needs.
