A good wooden door should not be too light. Compared with several kinds of wooden doors with the same specifications and the same surface layer, the wooden doors with too light weight can hardly be said to be high-quality wooden doors. The reason why the weight is too light is that the core material is soft (e.g. poplar), and the pipes and voids in the wood are relatively large. Or maybe the core material inside is too little, which makes the wooden door not strong enough. The strength and impact resistance of this kind of wooden door are poor, and the sound insulation effect is not good.
Second, look at the appearance (lacquer and veneer) of high-quality wood doors with full and smooth finish, rich and natural, transparent paint film, clear and lifelike texture of surface materials, and a glance at the physical properties of the appearance. Low-quality wood door paint film is dry and obscure, dew paint, bubbles, pinholes, ripples, particles and so on are more, the transparency of paint film is poor, the surface texture is blurred, and the appearance of wood is obscure and difficult to distinguish. The reason why inferior wooden doors are so bad is that the paint quality chosen by manufacturers is poor and the technology and equipment are not up to standard. On the other hand, there are many defects in the wood skin chosen by manufacturers, so the transparency of the coatings is intentionally reduced to cover up the defects such as dead joints, holes, decay, discoloration, cracks and indentations on the surface.
Thirdly, it can be seen that the processing of the bark or solid wood joints of the high-quality wooden doors is relatively fine, and no trace of the combination can be seen. Low-quality wood doors, wood or solid wood joints are obvious, and even cracks and dislocations.
Fourth, high-quality wooden doors have strict requirements on material selection, process control and factory inspection. The finished wooden doors have flat and straight surfaces. Perfect appearance after installation. Low-quality wooden doors have low requirements for materials, technology and inspection. The warpage of finished wooden doors is large. It is obvious that wooden doors and doorframes can not be neat after installation.
