1. According to tree species: divided into coniferous wood (such as pine, cypress, etc.) and broadleaf wood (such as beech, birch, poplar, etc.).
2. According to the use of points, divided into the original article, logs, sawn timber three categories.
3. According to the material, logs are divided into one, two, three, etc.; sawn timber is divided into special grade, first grade, second grade and third grade.
4. According to weight density, it can be divided into light-weight - less than 400 kg/m3. Medium wood - The bulk density is 500 to 800 kg/m3.
Common wood:
1. Red pine: light and soft material, moderate strength, good drying, water resistance, corrosion resistance, processing, finishing, coloring, good cementability.
2. Baisong: The material is light and soft, elastic, fine and uniform structure, good drying, water resistance, corrosion resistance, good processing, finishing and coloring. White pine is stronger than red pine.
3. Birch: The material is slightly hard, with fine structure, high strength, good workability, finish, and gluing.
4. Paulownia: The material is very light and soft, and its structure is rough. The cut surface is not smooth, and it is dry and not cracked.
5. Beech: The material is slightly lighter and softer, and the structure is slightly finer. It has a silky luster, is not easy to crack, and has good processing, painting, coloring, and cementation. Not resistant to corrosion, slightly warped when dry.
6. Ash: material is slightly hard, beautiful patterns, rough structure, easy processing, toughness, finishing, good adhesion, dryness in general.
7. Beech: beautiful patterns, rough structure, processing, finishing, good adhesion, poor drying, easy to crack warping.
8. Beech wood: hard material, rough structure, high strength, difficult processing, coloring, good finish, poor glueability, easy to dry, easy to crack.
9. Beech: hard material, straight texture, fine structure, wear-resistant and shiny, not easy to deformation when drying, processing, finishing, good gluing.
10. Maple wood: moderate weight, fine structure, easy processing, smooth cutting surface, good finishing and gluing, warping when dry.
11. Beech: moderate weight, fine structure, aroma, not easy to be deformed when drying, processing, painting, and gluing are better.
12. Willow: moderate material, slightly thick structure, easy processing, good bonding and finishing. Slight cracking and warping when dry. Plywood made from Willow is called a Philippine board.
13. Rosewood: hard material, texture, medium structure, corrosion resistance, not easy to dry, smooth cutting surface, coating, good adhesion.
14. Red sandalwood (redwood): Hard material, more texture, coarse structure, strong durability, shiny, smooth cutting surface.
15. Artificial boards, commonly used are plywood, plywood, fiberboard, particleboard, hollow board and so on. Due to the different composite structure of various wood-based panels, it can overcome the shortcomings of wood expansion, warping, cracking, etc., so it is used in furniture, has many advantages.
Picking wood notes:
1. Wood should not crack, warping, color, texture smooth.
2. Wood cannot decay, discolor, and pests.
3. Must be dried and the moisture content must not exceed 15%.
