Grade 4 (C) - Plywood is a type of plywood and is used in a variety of construction and furniture applications. This type of plywood is typically classified according to a grading system used to determine the quality of veneers. The term "4(C)" in this classification usually indicates the surface quality and smoothness of the board. However, it is important to note that these classifications may differ between different manufacturers or standards. It is therefore important to refer to a specific manufacturer or local standards for accurate information, especially for a specific product or standard.
Many manufacturing defects are allowed. At the same time, the manufacturer guarantees a strong bonding of the boards.
