Plywood is extremely versatile, with applications ranging from interior to structural to exterior. It can be used to complete jobs ranging from formwork to panelling. But what exactly is plywood, and how is it manufactured by plywood manufacturers? This post will answer these questions and explain why plywood is such a versatile material for both outdoor and indoor construction projects.
Plywood is a type of wood that is made up of thin layers or “plies” of wood veneer that are glued together, with adjacent layers getting their wood grain rotated up to 90 degrees to one another. In its most basic form, plywood is made by glueing together wood veneers to form a flat sheet.
Depending on their intended use, plywood pieces are formed differently by plywood manufacturers. For example, if the plywood is to be used for construction, it is pressed into large flat sheets. Curves are formed if it is to be used in the construction of aircraft, boats, or furniture. Every ply layer has grain that runs at right angles. This helps to keep the layer strong as well as durable while also reducing the possibility of shrinkage. The plywood itself is made up of at least three layers of wood which are held together with an adhesive.
The back and face of the plywood are the two outside areas. The back is usually the part that is hidden from view, while the face is visible. The layer in the middle is known as the core, and if five or more plies are used, the additional internal layers are known as crossbands.
How plywood is made is heavily influenced by the materials used. Softwoods and hardwoods can both be used to make plywood. It can also be made of a combination of the two. Softwoods commonly used to make plywood include cedar, pine, redwood, and spruce, but Douglas fir is the most commonly used.
The core of composite plywood will be made of either solid lumber or particle board. When a project requires very thick sheets, composite plywood is typically used.
There are numerous adhesives that can be used to join the layers of wood to form a sheet of plywood. The type of plywood used is determined by its intended use. If the sheets are to be used on the exterior of a structure, for example, a phenol-formaldehyde resin will be used. This is due to the adhesive’s high strength and resistance to moisture damage, which is essential for any outdoor project.
If the plywood is to be used in the interior of a structure, the adhesive is typically made from either a soybean protein or a blood protein. However, a lot of these interior plywood sheets now use the same phenol-formaldehyde resin as exterior sheets. Finally, if the plywood is going to be used by Plywood Manufacturers to make furniture, the adhesive is usually a urea-formaldehyde resin.
Other materials can also be used in the Plywood Manufacturers. Some projects, for example, require a layer of metal, plastic, paper, or fabric to be bonded to the back or face, and sometimes both, of the plywood. This increases the sheet’s resistance to moisture. Overlaid plywood is a type of plywood that is commonly used in the transportation, agricultural, and construction industries.
In general, plywood is classified into two types, each with its own grading system. Construction/industrial and hardwood/decorative are the two classes. The plywoods in the construction/industrial classification are used for their strength. They are classified based on the type of veneer used on their back and face, as well as their exposure capability. The type of adhesive used usually determines whether the exposure capability is exterior or interior. This classification includes veneer grades D, C, B, A, and N. The D grade has the most defects, whereas the N grade has very few defects. As a rule of thumb, plywood used for subflooring has a rating of C to D.
The hardwood/decorative classification of plywood can be used for its overall attractive appearance. The ability of the plywood to resist moisture determines the grade in this class. Given that it is used for decorative purposes, the face of this plywood is almost always free of defects, at least to the naked eye. Type III, Type II, Tile I, as well as Technical are the classifications.
