How much do you know about wood species such as cherry, walnut, and eucalyptus? Laminated materials, finger-joint materials... These seemingly unfamiliar terms may in fact be part of your solid wood door, and they directly affect the quality of your home's purchase of wooden doors. Therefore, before selecting the wooden doors, it may be helpful to understand their general materials first, which will help you choose a more suitable wooden door.

Cherry wood imported and made
If you want to buy solid wood doors, the names of the wood on the market may make you dizzy, they are of various materials, and the scientific name, commonly known as mixed, to distinguish clearly not easy. According to Wu Shengfu, director of the Marketing Department of the China Forest Products Industry Association, wood commonly used for wooden doors (which can be used as wood in solid wood and can also be used as surface decorative materials) includes Sapele, rosewood, teak, cherry, walnut, and maple. Wood, beech (alder, oak), ash, hemlock, southwestern birch, pine, fir (all of which are market names). Among them, the cherry wood has both imported and domestically-made, and its price is not the same. We must beware of the business to “steal the barâ€.
Cherry wood: Rosaceae, also known as American black cherry. Mainly produced in North America, the United States mainly for commercial materials. The core material is dark red to light reddish brown. Wood has good bending properties, low hardness, moderate strength, and impact resistance. Selected logs can be used to make furniture and cabinet veneer veneers, wall panels and glossy doors. Because of the beautiful texture of cherry wood, and all imported large diameter wood, the price is relatively high.
At the same time, there is a kind of wood produced in southern China, Myanmar, Laos - Betula alnoides, between the cherry wood and Sapele texture, known as the domestic cherry wood known. This kind of wood has high hardness and quality, light brown color, beautiful wood grain and easy processing. Because of its beautiful cherry wood pattern, its cost is lower than imported cherry wood. However, some unscrupulous merchants in the market may be “difficultâ€. It is recommended that consumers ask clearly when purchasing, and the salesman confirms that they are imported cherry and implement it in the contract.
Glued wood is better than natural wood
In the eyes of many consumers, if you choose a solid wood door, natural wood is definitely better, and it is both environmentally friendly and beautiful. In fact, solid wood doors have gradually become an unrealistic pursuit of products. The reasons are as follows. First, the status quo of raw material supply does not permit large-scale use of solid wood panels, and solid wood doors are produced using a combination method. Second, solid wood panels are susceptible to cracking and deformation. The third is that the woodworking process using a combination of crucibles is not easily integrated by modern processing techniques. Wu Shengfu believes that Glulam retains the beauty of natural wood and has an advantage in physical properties.
According to reports, glulam (glue wood) is a material obtained by integrating stencils, small squares, etc., in which the fiber direction is substantially parallel, in the length, width, and thickness directions. According to reports, the glulam is made from the short material of solid wood to the required size and shape, so that small materials can be used in large quantities, and inferior materials can be used. By removing wood defects such as knots and rot before glueing, materials with less defects can be produced. With the panel, wood defects can be dispersed even with wood defects. If there are special needs, the plates can be treated with different drugs in advance before glueing. Even if the materials are long or large, they can have sufficient chemicals inside, so that the materials have excellent anti-corrosion, fire resistance and insect resistance.
Compared with natural wood, Glulam has not changed the structure and characteristics of wood. It is still a natural substrate, retaining the texture of natural wood and beautiful appearance. From the point of view of physical and mechanical properties, it has good stability and is not easy to produce cracking deformation. It is also superior to natural wood in terms of uniformity of material quality. In addition, since the raw materials are fully dried, the moisture content of all the parts even in large-section and long-sized materials is uniform, and the cracking deformation is smaller than that of natural wood.
Three ways to distinguish finger boards
Finger joints are also one of the most important materials for solid wood doors. What does that mean? The finger joint material is a board material made of sawn timber as a raw material by means of finger boring processing and gluing and joining. It is to lengthen the timber for lengthening. The finger joint material is made into a finger-joint plate after horizontally widening.
The finger-joint board is also divided into two types: knotted and non-segmented. There are knotted eyes that are blinking, no knots that are not blinking, and are more beautiful. How should consumers identify finger boards? Experts taught three simple and easy methods: First, look at the ring of core materials. The finger-jointed plates are mostly made of Chinese fir and pine wood. The annual rings are more obvious. The annual rings are smaller, which means that the tree is of a long age and the material quality is better. Second, look at the gums. The finger-plates are divided into horizontal and vertical types, and others are said to have dark teeth and bright teeth, and horizontal dark teeth. Because bright teeth are more prone to unevenness after painting, darker teeth are better, and darker teeth are more difficult to machine. Third, look at the wood hardness. Wood hard fingerboards are better, because the hard deformation of the material is relatively small, and the pattern is more beautiful.
