Pine: There are two main materials for pine furniture, one is Pinus massoniana, and the other is Pinus sylvestris. The texture of Masson pine is straight or uneven, and the structure is medium to thick. The disadvantage is that the cracking is more serious when drying. Not resistant to decay. Poor paint and bonding performance. The nail-holding force is strong, relatively speaking, it is less used as furniture in wood furniture. The price of wood-board is generally about three times that of the same size fir integrated board or large core board. Pinus sylvestris var. mongolica is widely used as the material for mid-range solid wood furniture. Many log furniture uses pine wood. The pine material is stronger, the texture is clearer, and the wood is better. Compared with Chinese fir, the wood grain of Pinus sylvestris is more beautiful.
