What is the actual thickness of 3/4 inch plywood?

Plywood is often sold in 1/4“, 1/2“, or 3/4” nominal thicknesses, but the actual thickness is often 1/32” thinner. Because the actual thickness may vary measuring the plywood is the only accurate way to determine its thickness. A 3/4” sheet is actually 23/32” thick.

Is 15 32 The same as half inch?

The reason un-sanded plywood, such as sheathing, is described as 15/32-in. thick is to reflect the manufacturer's tolerance of 1/32 inch, even though in layman's terms the sheet is equivalent to a 1/2-in.22-May-2018

What does CDX stand for in plywood?

CDX signifies class C to D exposed plywood. Manufactures make any type of plywood from several plies pressed firmly together to create a larger and stronger piece of plywood.

What is the strongest 3/4 plywood?

The answer is marine plywood. It is the strongest and toughest of all plywood on the market. High-quality glues hold the plies in marine plywood together. That makes them structurally sound and resistant to moisture.10-Apr-2018

Is OSB stronger than plywood?

Osb is stronger than plywood in shear. Shear values, through its thickness, are about 2 times greater than plywood. This is one of the reasons osb is used for webs of wooden I-joists.

How thick is plywood?

Because the actual thickness may vary measuring the plywood is the only accurate way to determine its thickness. A 3 / 4 ” sheet is actually 23 / 32 ” thick.

Why is plywood different thickness?

Another reason for varying plywood thicknesses is a range of manufacturing tolerances. Sheets are available in hardwood or softwood veneers, and in varying grades including sanded and unsanded. These different grades have different manufacturing tolerances and may vary more or less from the 3 / 4 ” nominal thickness.

What is plywood panel?

Plywood is a wood panel that is composed of several thin layers, or plys, of wood veneer. It comes in various thicknesses and sizes, and is typically sold by its nominal thickness. While the length and width are often the actual dimensions, the nominal thickness is usually different than the actual thickness.

Why does plywood shrink?

There are a few reasons why the actual thickness of plywood varies. First, wood shrinks as it dries and moisture leaves the wood. This means that a sheet of plywood that started at 3 / 4 ” may shrink slightly after manufacturing.

Is plywood sold by the board?

Plywood is usually sold by the sheet, but in some rare cases it may be sold by the board foot. Board footage is a measure of the volume of wood in the sheet. Our board footage calculator can help calculate how many board feet you need if your plywood is sold using that measure. The weight of a panel will vary by thickness and the type.

Is plywood thinner than plywood?

Plywood is almost always thinner than the nominal measurement due to the fact that most tooling in furniture and cabinet factories and manufacturing facilities can accommodate plywood that is thinner than expected but not thicker than expected.

What are the grades of plywood?

The grades are A, B, C, and D . However, every piece of plywood has two grades per compound, shown as AB, BB, BC, and so on. The first letter represents the face veneer grade, while the second letter represents the back veneer grade. Simply put, the higher the grade, the better.

What is the difference between B grade plywood and A grade plywood?

The key difference between B-grade and the A-grades is that B-grade plywood are allowed to have some changes in color that show the pattern of the grain. They may also have had some repairs in the past, but have a smooth surface and reliable foundation.

What is the best plywood for outdoor use?

They’re quality materials, but don’t have much ability to tolerate moisture, which makes them unsuitable four outdoors but also makes them less expensive. Pressure-treated plywood and CDX sheathing are better for outdoor use.

What is the standard size of plywood?

Common Plywood Sheet Sizes. Hardwood Plywood comes in many lengths and widths, but the two most common sizes are 4 x 8 and 5 x 5 feet. Standard sheets are 1/2 inch thick, while non-standard thicknesses range from 1/8 inch to 3/4 inches.

How much does plywood weigh?

In addition to being sturdy, plywood is also heavy. It weighs about 2.5 lbs per square foot, meaning a standard 4×8 sheet weighs 80 lbs. Of course, it’s also highly absorbent, so this weight will increase if the board gets saturated. Read on to learn about the standard plywood sheet sizes and types you can buy.

What is hardwood plywood?

Hardwood Plywood. This is made from Alder, Ash, Beech, Birch, Bamboo, Cherry, Mahogany, Maple, and other hardwood trees. Hardwood is used for carpentry projects like cabinetry, making furniture, and other decorative applications. Sheets are usually sanded to make a smooth surface and can be stained or painted.

How thick is plywood?

Plywood’s Actual Thickness. Although standard plywood sheet sizes range from 1/4 to 3/4 inch thicknesses, it’s actually slightly thinner. This is because after it’s manufactured, plywood shrinks as it dries. So, when you are buying a standard utility-grade sheet, the actual size will be as follows:

What is plywood made of?

Plywood is not a specific type of wood, but rather a category of material made from thin layers of wood glued together to form long sheets. The grain of each layer is rotated 90 degrees to improve strength, reduce shrinkage, and prevent the wood from splitting. Sub-categories include MDF, OSB, and particle board.

What is the tolerance of utility grade plywood?

While this varies by type, utility-grade sheets have a tolerance of 1/32 inches and cabinet-grade sheets have a tolerance of 1/64 inches. This means that higher-grade plywood is held to a higher standard than lower-grade material.

Does plywood shrink when wet?

In fact, all wood expands as it gets wet and shrinks as it dries. Remember, plywood is made from many layers of thin wooden sheets. And the top layer needs to be sanded after the sheet is made. During this process, 1/32 inches is typically removed from each sheet.

Uses of Plywood

Plywood is an engineered wood from the manufactured boards family which includes particle board and oriented strand board (OSB). It is made from thin sheets of veneer peeled from debarked wood. These thin layers, also called plies, are glued together in alternating right angles to create a cross-grain pattern.

Types of Ply

A ply refers to a layer of veneer used to create plywood’s various thicknesses. More ply creates a thicker and stronger board. Plywood has an odd number of plies and needs at least three plies. Although specialty plywood can have any number of plies above three, most plywood is categorized as 3-ply, 5-ply or multi-ply.

Plywood Ratings, Grades and Sizes

Plywood is sold in various ratings, grades and sizes. Make your selection based on the type of project you’re working on.

Plywood Alternatives

You can use other types of boards in place of true plywood. They may even be commonly referred to as plywood, despite being manufactured differently. Although not technically plywood, other engineered wood boards and panels can be great options for construction projects when you want to save money or have a different look and feel.
