Heat treatment: Heat treatment is a method of changing the physical and chemical properties of wood by heating it. This treatment method can increase the hardness, stability and durability of wood.

Compression treatment: Compression treatment is a method of compressing wood to a higher density. This treatment method can increase the hardness and strength of wood.

Chemical treatment: Chemical treatment is a method of changing the physical and chemical properties of wood by injecting chemicals into it. This treatment method can increase the hardness, corrosion resistance and durability of wood.

Surface treatment: Surface treatment is a method of increasing the hardness and durability of wood by adding coatings or polishing on the surface of wood. It should be noted that these treatment methods have their advantages and disadvantages and scope of application, and need to be selected according to actual conditions.
