The substrate is generally made of aluminum alloy and plastic steel. Due to its light weight and high strength, aluminum alloy is a high-grade material for sliding door substrates, which has gradually replaced plastic steel products. The aluminum alloy is divided into ordinary aluminum-magnesium alloy and aluminum-titanium-magnesium alloy. The metal titanium has the characteristics of high strength, small specific gravity and high toughness, so the price thereof is several times more expensive. In addition, advanced surface treatments include anodizing, electrophoretic coating, carbon coating, etc., which have higher hardness and aesthetics than simple spraying and plating.
MDF: There are weight, feel, low price, poor quality will be deformed, and the back of the good MDF will have the company's stamp.
Glass: The surface has a pattern, which has the characteristics of light and opacity; carved glass: the painted pattern generally has a personality "creative"; stained glass: the film has strong adhesion and can be scrubbed.
There are also metals, aluminum alloys and other materials, from the decorative wood closer to nature, metal and organic materials are modern.
Also choose according to the location of use, such as the wardrobe sliding door is generally wooden, the balcony sliding door is generally tempered glass.
Partition: As a partition door, most of them are relatively transparent panels, which can make the space more open, take into account the decorative effect, and match the overall living room style.
Door: The material is wood, glass, mirror and others. The height of the glass sliding door should not exceed 2.5 meters. It is not advisable to choose the mirror sliding door in the bedroom. The sliding door of the plate is simple and generous, and has good safety. In addition, there are also louver series sliding doors and sliding doors.
Sliding the sliding door in the vertical direction of the slide rail, the smaller the degree of shaking, the better the stability. When shaking, pay attention to the upper pulley and the upper rail. If the sliding door is of good quality, the gap between them is almost zero, so that there is no vibration feeling when sliding, smooth and smooth. Therefore, the tight combination of the upper pulley and the slide rail determines the smoothness of its sliding.
It is advisable to select a built-in bearing bottom wheel with a large bearing capacity. This bottom wheel is high in technology and can cope with various conditions. In addition, the quality of the sealing brush is also important, it is attached to the back of the door. The good quality seal brush has a high viscosity and no fading of the bristles. When closed, the door and the door are tightly joined, so there is no need to worry about dust intrusion.
The stop block is generally made of steel sheet, but the steel has a good durability and the steel is not good. After a long collision, the displacement will occur, so that the sliding door cannot be stopped. In fact, metals have fatigue periods, which are easily deformed after a long period of work, and the stoppers made of copper are corrosion-resistant and can be stable for a long time. Therefore, such materials can be selected as much as possible.
It is considered that the sliding door is lighter and better as it slides. In fact, this view is wrong. The sliding door with high quality should not be too light or too heavy when sliding, but with the weight of a certain door, push and pull. There is no vibration, smooth and textured. Some mobile sliding doors are lighter to push and pull, but there is a feeling of "floating" out, not smooth enough. Be careful about the feelings of sliding.
With or without noise
The general cause of noise in the sliding is the process difference of the bearing pulley and the gap between the pulley and the rail. Although some of the bottom wheels slide smoothly at the time, a closer look reveals a greasy feel on the bottom wheel. This is because some sellers have oiled the bottom wheel for the purpose of sliding silence. This is not only easy to contaminate the dirt, but once the grease is dry, it will become blocked and produce noise.
Bottom wheel pros and cons
Only the bottom wheel with super-large bearing capacity can guarantee its good sliding effect and long service life. The high-grade mobile sliding door is made of carbon fiber glass with inner ball and non-dry lubricating ester. The poor pulley is often made of engineering plastic or organic plastic. The bearing capacity is small. It may not be harmful to start using. It takes a long time to deform and affects the push-pull effect.
When selecting, pay attention to the settings of other small accessories such as anti-jumping device, shock absorbing device, height adjustment system, dust brush, rubber strip at the joint of glass and metal frame.
The size of the track box on the upper part of the sliding door is guaranteed to be 12 cm high and 9 cm wide. When the height of the door is less than 195 cm, it feels very depressed. Therefore, when doing sliding doors, the height must be at least 195 plus 12 = 207 cm. The gold size of the normal door is about 80 cm × 200 cm. Under this structure, the door is relatively stable and beautiful. Therefore, the ratio of the width and height of the sliding door should be similar to the size of the gold.
