By combining the layers of wood veneer, plywood is brought to life. It is a sheet material made up of different layers glued together. With the help of a cross-graining process, you can rotate each layer up to 90 degrees. As a result, it can enhance the strength of the product. The process of cross graining is vital to help plywood resist splitting, minimize expansion, and shrinkage. The highest quality of the plywood sheet does not wrap easily. For that purpose, this process uses an odd number of layers to provide a balanced sheet that will last long.
