Lumberis a wood product, sawn and shaped from timbers of harvested trees. By its nature, wood is not of uniform consistency and therefore will contain defects that impact the appearance of the lumber that is created from the wood material, and which may impact the structural characteristics as well. In the U.S., lumber is assigned a grade which establishes a measure of consistency in the final products produced by mills. These grades are used to define both the quality of the lumber products delivered See more on thomasnet pine wood lumber e f gradeEstimated Reading Time: 8 minsKyorichi Wood (Henan) Co., Ltd. ,Timber Raw Materials pine wood lumber e f gradeWood Species: Chinese/Japanese Cedar, Paulownia ** Finger Jointed Lumber Finger Jointed panels; Finger Jointed Strips for furniture; Moulding.
