Plywood has a lot of strength, very good toughness, medium density fiberboard material is more uniform, suitable for processing. Plywood is a three-layer or multi-layered sheet ingenuity made of a wooden segment that is rotated into a single board or cut into thin wood by a wooden side, and then glued together with adhesive, usually with odd layers of single board, and the fiber direction of adjacent layers of single board is made of vertical plying each other. So what are the principles of symmetry of plywood?

1, if the symmetrical position of single-plate chips have two places, it is possible to be manufactured in the same way, the direction of the fiber is parallel.

3, if the center of the single plate of the center of the chip and the symmetrical center of the plywood coincides, the number of chips on the plywood should be odd. Copyright © Shandong Unique International Trade Co.,Ltd All Rights Reserved.

4, plywood above all have cross-section, and the number of chips on both sides of the center is the same, symmetrical position of the green plate is equal distance. The above is a detailed description of the principle of the symmetry of plywood, after understanding the above, will help you to choose plywood later, and to be able to have more understanding of plywood.
