The imported wood is mainly processed from pine, eucalyptus, fir and other trees into wooden strips with a rectangular or square cross section. The specifications of the wood are generally divided into 30*50 mm. This refers to its length and width. We call it 3 5 squares. This is generally used for hanging wooden keels, or for making some internal structures. 60*90, the frame of the general old-fashioned furniture is made with this, but it is rarely seen in home decoration. 120*40, called the door side. It is used to make the skeleton of the door. On both sides, the board is sprayed with paint, and one door is made.
