(1). The face has some dead knots, minor spots, and discoloration; the back has large areas and deterioration.
(2). The plywood is frequently not sanded and therefore not very smooth. The tolerance for thickness is a little wider.
What are the five different grades of plywood?
There are four fundamental softwood (construction) plywood veneer grades to be concerned about in the United States: A, B, C, and D. You might come into a fifth grader known as “C-plugged” on occasion.
There will be two grades on each sheet, such as AC. The first letter denotes the quality of the face veneer, while the second denotes the grade of the rear veneer. A third letter, X, indicates that the plywood is suitable for outdoor use. Here’s what to look for in plywood grades, from highest to lowest quality:
“I got an A.” Paintable after being sanded smooth. Though some carefully executed manufacturer fixes are acceptable, finding A-grades that are devoid of repairs and knots should be rather easy.
“I give it a B.” Repairs, commonly football-shaped patches and/or wood filler, to a solid surface. Up to 1 in. of tight knots (no chunks of wood missing). There are few minor divides.
“The grade is a C.” Some splits and discolouration, tight knots to 1-1/2 in. and knotholes to 1 in.
“I got a D.” Knots with knotholes with a diameter of up to 2-1/2 in. There are some splits. In most cases, no repairs are required.
Even within the different plywood grades, the amount of repairs or flaws is likely to vary greatly. Visit the American Plywood Association for additional information about softwood plywood. You’ll learn about plywood’s usage, grading, and specifications.
What are the three different varieties of plywood?
Plywood comes in a variety of shapes and sizes:
Face and back (top and bottom) plies of sanded plywood are sanded throughout the manufacturing process. Cabinets, shelves, and paneling are examples of places where it is evident.
Hardwood plywood is created from birch, maple, and oak trees. The plywood is particularly robust and solid since the plies are joined at perfect angles to one another. It has the potential to be heavier than other plywood varieties. Furniture and other items that require a robust load-bearing frame should be made using hardwood plywood.
Plywood sheathing, often known as structural plywood, is intended for long-term use. It’s sturdy and affordable, but it’s unfinished, so it’s not suited for public areas. Other materials should be used to cover it. For framing, beams, flooring, and bracing panels, use plywood sheathing.
Project plywood panels are pre-cut plywood boards that are ready to use for quick and easy DIY projects. There are many different varieties of wood, ply, and plywood to choose from. When you have the measurements, use this for planned DIY projects. It’s an excellent material for novice DIYers.
Markerboard is made out of plywood panels with a coated writing surface that can only be written on using dry erase markers. It’s perfect for craft tables and completed markerboards.
What are the four different grades of plywood?
Let’s face it: knowing exactly what grade or type of plywood is best for any given type of building project can be difficult unless you are knowledgeable with all of your alternatives, including the labels on such types of plywood (which can be confusing). Some plywoods are lighter, less expensive, more durable, more resistant to the elements than others (not to mention more aesthetically pleasing). Furthermore, the best sort of plywood for an outside project, such as a porch or deck, may not be the best plywood for an indoor job, such as flooring or cabinetry. Other varieties of plywood may be required for projects such as a boat hull, a shed, or a treehouse.
Plywood is one of the most widely used materials in the United States; according to Statista, the total production of plywood and veneer in the United States in 2016 was approximately 683 million cubic feet. Plywood veneer or’sheets’ come in four different grades: A, B, C, and D. Each veneer is divided into two grades, with the appropriate compounds denoted by letters such as ‘AB’ or ‘BC.’ The first letter denotes the ‘face’ veneer, while the second denotes the ‘back’ sheet. If a plywood compound’s name ends in an X, it suggests it has been exposed to moisture to some extent. Plywood sheets are aligned perpendicularly to each other by definition. Plywood is available in many thicknesses, such as 1/2-inch, 1/4-inch, and 3/4-inch.
A-grade plywood: Because the veneers are perfect, this is the highest-quality plywood and also the most expensive. Paintable A-grade plywood is smooth and easy to work with.
B-grade plywood: B-grade plywood has a firm foundation and is slightly less smooth than A-grade plywood. It typically has minor defects and can be repaired.
C-grade plywood has a few knots up to 1.5 inches in diameter in its sheets.
D-grade plywood: The least expensive sort of plywood veneers, these sheets are usually undamaged. The faults in this type of plywood can be slightly greater, and the knots can be up to 2.5 inches in diameter.
CDX: Because it is made up of the two lowest classes of plywood, CDX-grade plywood is often inexpensive (C and D). It can also endure a certain amount of wetness. CDX plywood is ideal for use in the construction of work tables and storage boxes.
Sanded Pine: Sanded pine is a versatile type of plywood that has a smooth and clean surface and holds screws and nails securely. It’s ideal for constructing boxes and cabinets.
Baltic Birch: A flexible material with clean edges and a smooth finish, Baltic birch is often more expensive because to its clean edges and smooth finish.
Oriented Strand Board (OSB): Also known as “wafer board,” this form of plywood is made from wood chips and has a flaky appearance. Its patchwork design is made up of wood chips of various sizes, shapes, and colors that are glued together.
The ability of a particular type of plywood to endure snow, rain, and other types of weather is determined by factors such as heat and moisture.
Because it is saturated with chemicals, pressure-treated plywood is very resistant to mold and mildew. Pressure-treated plywood is long-lasting and doesn’t require the application of paint or other protective coatings.
CDX sheathing: CDX sheathing is a low-cost plywood that should never be left exposed. Roofs, garages, and storage bins are frequently covered with bricks or shingles.
Marine-grade plywood, which is lightweight and manufactured with waterproof glue, Medium Density Overlay (MDO), and Southern Yellow Pine, which is perfect for roof and wall sheathing applications, are all prevalent varieties of plywood.
Curtis’ experts are extremely skilled and aware about various varieties of plywood. If they don’t have what you’re looking for in stock, they’ll try to find it for you. For specific projects, they can also provide direct trailer load shipping and even pull orders to the piece.

Which plywood is the most durable?
Exterior plywood should be used wherever where weather exposure is a problem, such as the exterior walls of a house. Exterior plywood, on the other hand, can be used inside, in places like kitchens, bathrooms, and basements.
By linking all of the studs, the plywood used to sheath house frames strengthens the structure. This type of sheathing necessitates significantly thicker plywood than typical.
What type of plywood is water-resistant?
Have you ever wondered what type of plywood is the most durable? Marine plywood is the answer. It is the toughest and most durable plywood available.
The plies in marine plywood are held together by high-quality glues. As a result, they are both structurally sound and moisture resistant. Marine plywood is often only available in A-A grade, which implies either side can be shown on the surface.
Marine plywood is an excellent alternative for bathrooms, basements, and as a substrate for laying hardwood engineered flooring and tiles due to its strength and water resistance.
What is the right plywood to use for high-traffic areas?
Structural plywood is extremely strong and durable, coming in second only to Marine plywood in terms of strength and longevity. This sort of plywood is ideal for high-traffic areas like hallways and entryways. It usually comes in grades C-D or D-D and has a rough texture.
What type of plywood is best for usage outside?
What is the best type of plywood for outdoor use?
- Exterior plywood is weather (and water) resistant, making it suitable for use both outside and in spaces where water and humidity are present, such as a garage.
- There are several different varieties of exterior plywood to pick from, with CDX and ACX being the most typical.
Is OSB superior to plywood?
In osb, wood fiber is used more effectively. In shear, osb outperforms plywood. Shear values are approximately 2 times more than plywood due to its thickness. One of the reasons osb is utilized for webs of wooden I-joists is because of this.
On plywood, what does BC stand for?
Exterior glue, B-grade sanded veneer front, C-grade cores and back. The face of BC plywood Pine will have been fixed to remove any knots or other problems. Exterior sheathing, soffits, cabinets, shelving, and paneling are all examples of uses.
