A group of veneers are usually formed and glued perpendicularly to each other in the direction of adjacent wood grains, and are symmetrically arranged on the center layer or the board core on both sides of the worktable and the inner board. A flat plate with a single plate is gelatinized into a cross shape according to the direction of the crystal grains, and pressed under heating or unheated conditions. Generally, the number of layers is odd and the number of even layers. The difference between mechanical properties and physical properties in the vertical and horizontal directions is small.
