Finger jointed board is a kind of man-made board made of wood strips about five centimeters wide. Some people don't know much about finger joints, so I will teach you how to easily identify finger joints. Identify the finger joint board, mainly look at its core material growth rings, the finger joint board is mostly made of fir wood, the growth rings are more obvious, the larger the annual rings, the longer the tree age, the better the material of the finger joint board.
Another way to do this is to look at the tooth marks. The finger joint plate is usually divided into open teeth and dark teeth, among which the finger joint plate with dark teeth is better, because the finger joint plate of open teeth is more prone to some unevenness after painting, and of course, the processing of dark teeth is more difficult. The wood is hard, and the finger joint board is of good quality, because its deformation is much smaller than that of ordinary boards, and the pattern is more beautiful.
