A lot of plywood is made by pasting two different veneers together, and the plywood that passes the standard is spliced tightly and flat without degumming. When purchasing, you should carefully observe the side, and pay attention to whether the joints are tight and whether there are unevenness.

When you tap various places on the plywood surface with your fingers, if the sound is clear and crisp, it means that the strength has passed the test to a certain extent. If the sound varies greatly from place to place, and there is a dull and dull sound, it means that the core of the plywood may have a hollow phenomenon.
