In order to improve the anisotropic properties of wood and make the plywood have uniform characteristics and stable shape, it is usually required that the plywood follow some principles in the structure: one is symmetrical, and the other is that the fibers of adjacent layers of veneer are straight. Symmetry refers to the veneers at both ends of the center plane of symmetry of the plywood. Regardless of the nature of the wood, the thickness of the veneer, the number of layers, the fiber direction, and the moisture content, they must be symmetrical to each other. In the same plywood, veneers of a single species and thickness can be used. It is also possible to use veneers of different tree species and thicknesses, but it should be noted that any two symmetrical veneer trees at both ends of the symmetrical center plane must have the same species and thickness, and the surface and backplanes may not be the same species.

What should be paid attention to when choosing plywood:

1. Different types, grades, materials, decorations and widths of plywood should be selected according to the nature of the project, the location of use, environmental conditions and other factors.

2. The decoration should use wood sliced veneer veneer.
