The composition of wood veneer can vary according to different types and processes, but in general it can be divided into the following parts:

1. **Base material**:
- **Artificial board**: including plywood, high-density board, solid wood multilayer board, woodworking board, etc. These boards are usually used as the basis of wood veneer to provide the necessary strength and stability.
- **Original board**: that is, boards sawn from pure natural wood, directly using natural wood as the base.
2. **Decorative veneer (wood veneer)**:
- **Natural veneer**: thin slices sliced ​​from natural wood such as walnut, teak, beech, etc., with natural texture and color.
- **Artificial veneer**: including technical veneer, impregnated film paper, etc., which imitate the texture and color of natural veneer by artificial means.
3. **Balanced veneer (wood veneer)**:
- In order to prevent the wood veneer from deforming during processing and use, a balancing layer is usually added to the back, and the thickness of the veneer of the balancing layer is generally 0.1-0.3mm.
4. **Front decorative coating**:
- **Paint coating**: including matte paint, glossy paint, open paint, etc., which are sprayed or brushed on the surface of the wood veneer to provide protection and aesthetic effects.
- **Paint-free board**: such as melamine paper veneer, glass film veneer, etc., directly use paint-free materials as surface decoration.
5. **Back closed (balanced) coating**:
- In order to prevent the back of the wood veneer from getting damp or deformed, a closed coating is usually applied to the back.
6. **Other components**:
- **Process grooves and seams**: According to design requirements, the surface of the wood veneer can have different forms of process grooves and seams such as horizontal, vertical, and cross.
- **Connection structure**: The connection between the wood veneer and the wall, ceiling, and ground can be different ways such as close seams and joints
