[ Finnish quality grade, name and size]
Finnish sawn grades are mainly divided into A, B, C and D. A is the highest grade and is divided into four sub-categories A1-A4 according to the rate of out-put. There is no specific category division between B and C levels.
D-level only has verbal constraints and does not have detailed table data. It is the lowest quality level. Grade D has no restrictions on wood properties. Only the sawing wood must be cut and processed on each side.
Sawn lumber refers to sawn timber with precise dimensions and strict dimensional requirements. Cut about 1 mm with a high-speed planer at the time of sawing. After planing, sawmills may still have unplaned spots and burrs caused by planing. Planing sawn wood here refers to sawn timber that has a rectangular shape on all sides. At least 2 mm are cut on each side of the sawmill. The surface needs to be smooth, without burrs caused by bumps and planing.
Combining wood with other materials or technologies can lead to new types of wood products. Such as: plastic and wood synthetic wood-plastic composite or stress changes in the structure, etc., through fiber separation can make a new type of insulation program. Wood modification can improve wood properties, such as the use of charred wood.
[Finnish wood grade]
1st grade: No side (A grade)
2. Level 1: Shao Tree Festival (Level A + Level B)
3, mixed quality grade: mostly slipknot (B grade)
4, practical level: tree section is even (C level)
5, structure level: structural hidden parts, use many specifications.
[Finnish Wood Price]
Finally, let us look at the price of Finnish wood. After Xiaobian’s understanding of Finnish wood prices are still relatively high. Because Finnish wood production is not very large and it needs to be imported, the price is very expensive. In general, the original imported Finnish wood is about 300 yuan per ton. The finished wood of Finnish wood is quite high, and a piece of furniture may reach around 10,000 yuan.
Xiao Bian concludes: The Finnish wood grade is introduced here for everyone. After reading the above, I believe that we have a better understanding of the Finnish wood grade. If you need to learn more, please continue to pay attention to this website information platform.
