Plywood is a seemingly simple, but its combination of complex materials, it is composed of multiple layers of veneer by bonding a strong material. But if you have never understood the types of plywood, then when choosing it, you will face a huge problem. In order to help you better understand, we will introduce you to the main classification of plywood and the specific application in practice, hoping to help you provide a better reference in the future choice.
Plywood can be divided into: B, BB, CP, C class
Depending on the quality and appearance of the veneer, plywood is basically divided into B, BB, CP and C grades.
Grade B plywood (Quality grade) :
· Notable for its relatively smooth and uniform surface with few defects;
· Suitable for applications with strict external requirements, such as furniture, souvenir making, interior decoration, etc.
BB Grade plywood (Level 1) :
· Such plywood has some patches or knots, but the number is very small and the appearance is still attractive;
The application scenario is the same as the previous type of plywood, but the appearance is more textured, and in some projects, this feature is exactly what is needed.
Classified by surface treatment
In order to improve the decoration of the plywood surface, the surface will be frosted, the main atmosphere is the following categories:
Unpolished plywood :
· Unpolished plywood has a rough surface. In general, grade C(IV) plywood does not need to be polished. It is usually used for building structures where appearance is not important, such as decks or brackets.
Single side polished plywood :
· The material has a smooth surface. Suitable for projects that only require a visible display on one side, for example, a cabinet backboard.
Two-sided polished plywood :
· Both sides of the polished plywood are smooth. Suitable for projects with high requirements for the appearance of each side, such as shelves, floors, and so on.
