Beech plywood is a type of wood panel that is made from thin layers of beech veneer glued together under high pressure. Beech plywood has many advantages, such as high strength, hardness, shock resistance, and steam bending properties. Beech plywood is widely used for furniture making, flooring, worktops, workbenches, musical instruments, toys, and decorative veneers.
There are different types of beech plywood available in the market, depending on the quality of the veneer, the number of layers, the direction of the grain, and the type of glue used. Some common types are:

B/BB grade: This is the highest quality of beech plywood, with one side having a smooth and clear surface (B grade), and the other side having some minor defects such as knots or patches (BB grade). This type of plywood is suitable for applications where appearance is important, such as furniture or veneers.
BB/BB grade: This is a standard quality of beech plywood, with both sides having some minor defects such as knots or patches (BB grade). This type of plywood is suitable for applications where appearance is not critical, such as structural or industrial use.
BB/CP grade: This is a lower quality of beech plywood, with one side having some minor defects such as knots or patches (BB grade), and the other side having some major defects such as splits or cracks (CP grade). This type of plywood is suitable for applications where strength is more important than appearance, such as flooring or worktops.
CP/CP grade: This is the lowest quality of beech plywood, with both sides having some major defects such as splits or cracks (CP grade). This type of plywood is suitable for applications where appearance and strength are not important, such as packaging or pallets.
