Plywood It is a light, homogeneous, durable material, resistant to crushing, bending, stretching, tearing, and at the same time quite flexible and easy to precisely process. It can be bent, it allows for precise cutting of shapes and holes, both with the use of hand tools and CNC machines.
Depending on the needs and further use of plywood, the quality of their outer layer should be selected. We distinguish quality classes from I to III, where class I has the least acceptable defects. The right side can therefore be finished in quality classes I to III, while the left side always corresponds to quality class III.
