Door, it is the first impression of the home and its home, visitors always do not enter the house to see the door. The door is not only a partition of space, but also shows the taste and pursuit of the owner. 1, solid wood composite door The door core of the solid wood composite door is mostly made of pine, fir or imported filling material, and the outer density board and solid wood veneer are made by high temperature hot pressing, and the solid wood line is used for edge sealing. General high-grade solid wood composite doors, the door core is mostly high-quality white pine, the surface is solid wood veneer. Since the white pine has a small density, is light in weight, and is easy to control the water content, the finished door has a light weight and is not easily deformed or cracked. In addition, the solid wood composite door also has the characteristics of heat preservation, impact resistance, flame retardancy, etc., and the sound insulation effect is basically the same as that of the solid wood door. Due to the variety of styles of solid wood composite doors, rich styles, or exquisite European-style carvings, or Chinese classical color mosaics, or modern fashion, different decorative style doors give consumers a wide selection of space, which is also called solid wood style doors. The high-grade solid wood composite door not only has the characteristics of smooth handfeel and soft color, but also is very environmentally friendly and durable. Compared with the expensive cost of pure solid wood doors, the price of solid wood composite doors is generally around 1200-2300 yuan. For example, the higher-grade rosewood door is about 2,300 yuan; the medium-to-high-grade walnut, cherry, and Sapele wooden doors need 1,900 yuan. In addition, the veneer materials of modern wooden doors are more common with veneer and stickers. The veneer wooden door is rich in natural texture, beautiful and impact resistant, and the price is relatively high; the wooden door of the sticker is also called “grain wooden doorâ€. Because of its low price, it is a more popular product. The disadvantage is that it is easy to break and is afraid of water. . 2, solid wood door The solid wood door is made of natural wood from the forest, dried, and then processed by cutting, planing, boring, drilling, high-speed milling and other processes. Most of the solid wood doors are made of precious wood, such as cherry wood, walnut, teak, etc. The finished door has no deformation, corrosion resistance, crack resistance and thermal insulation. At the same time, the solid wood door effectively plays the role of sound insulation because of its good sound absorption. The natural wood grain texture and color of the solid wood door is undoubtedly the best choice for families who admire the natural decoration style. Solid wood doors have been warm since ancient times, not only beautiful, beautifully carved, but also diverse in style. The price of solid wood doors varies depending on the wood materials and texture. The market price ranges from 1,500 yuan to 3,000 yuan. Among them, high-grade solid wood has walnut, cherry, Sapele, rosewood, etc., and the fine teak door sells for 3,000-4,000 yuan. Generally, the high-grade solid wood door is better in the dehydration process, and the relative moisture content is about 8%. Thus, the formed wooden door is not easily deformed and cracked, and the use time is longer. 3. Molded wooden door Molded wooden doors are more affordable than solid wood doors and are safe and convenient, and are favored by middle-income families. The molded wooden door is mechanically pressed from two high-density fiber molded door panels with styling and simulated wood grain. Since the door panel is hollow, the natural sound insulation effect is worse than that of the solid wood door, and it cannot be wet. The molded wooden door is decorated with wood veneer and brushed with “varnishâ€, which maintains the natural texture of the wood. It can also be used for panel mosaic, which is beautiful, lively and economical. The molded door also has the characteristics of moisture proof, small expansion coefficient and deformation resistance. After a period of use, surface cracking and oxidative discoloration do not occur.
Power fitting Db Type Adjusting Plate is one Steel Plate with many holes but different hole distance;

it is applicable to insulation fitting for adjusting the length of twin-connecting or parallel-connecting insulator string through series connection with insulator string. The adjusting plate is also serially connected with the section of bundled conductor between connecting fitting & tension clamp subjected to tension insulator string as the looseness adjustment of two pieces of bundled conductor.
Link Fitting Pt Type Adjusting Plate is exclusively used for twin-connected rotation angle insulator string & tension insulator string. On usage, the adjustment of length to adjusting plate depends upon the rotation angle of angle tower to calculate the distance length between the two suspending points subjected to insulator string.
Our company is solemnly committed to the majority of customers: reasonable price, short production cycle, considerate service. We look forward to cooperating with you.
The most important thing is to choose the wooden door for performance and matching.
