Characteristics of sliding doors.


Border section

The base material of the sliding door is generally aluminum alloy and plastic steel. Because aluminum alloy has the characteristics of light weight and high strength, it is a high-grade material of sliding door substrate, and has gradually replaced plastic and steel products. Aluminum alloy is divided into ordinary aluminum magnesium alloy and aluminum titanium magnesium alloy, metal titanium has high strength, small specific gravity, high toughness and other characteristics, therefore, its price will be several times more expensive. In addition, advanced surface treatments include anodizing, electrocoating carbon spraying and other processes, which have higher hardness and aesthetics than simple spraying and electroplating.


If glass or silver mirrors are used as the door core, 5mm thick is generally used; If wood is used as the door core, 10mm thickness is the best. Some manufacturers in order to save material costs, use thinner wood (8mm or even 6mm) instead. Too thin wood, push and pull up appear frivolous, shaking, poor stability, and after a period of use, easy to warp deformation, card guide, resulting in not smooth push and pull, affecting normal use.

Lacquer finish

The paint is double-layer cautery before the spray transfer, that is, the surface dust removal and impurity cautery, which increases the adhesion of the paint, and the paint never falls off, and some small manufacturers' profiles are simply cautery, or even not cautery, so the paint is easy to fall off and the texture is not clear.

Large sliding door manufacturers of profiles surface are treated by the company itself, and then the use of imported advanced technology treatment, product paint smooth and delicate, uniform full, clear texture. Small sliding door manufacturers are from the profile factory wholesale finished products with color profiles, the surface can not be processed by themselves, the color is single, the door color is not interchangeable, such as the profile scratch in transportation or installation, when filling and the original door color does not match, color difference and other problems.


The wood (mainly fiberboard, particleboard) used for sliding doors are wood-based boards, and the adhesives used contain harmful substances such as formaldehyde. Many wall cabinet door manufacturers on the market, most of their wood is produced in the country, and even the use of coarse plate, many plate formaldehyde content exceeds the standard, distributed indoors, polluting the environment. In the northern cold season, when the doors and Windows are closed, the impact on the health of consumers is greater.

Pulley material

Pulley is the most important hardware parts in the sliding door, the material of the pulley on the market is plastic pulley, metal pulley and glass fiber pulley 3 kinds. The metal pulley is strong, but it is easy to produce noise when it is in contact with the track. Carbon glass fiber pulley, containing roller bearings, push and pull smooth, durable wear, box closed structure effective dust, more suitable for the large wind and sand in the north, two anti-jump devices to ensure safe and reliable sliding. And some low-grade sliding door wheels, made of organic plastic, easy to wear deformation, a long time to push and pull on the ups and downs, open wheel structure easy to enter dust wear internal bearings, it is difficult to protect the push and pull flexible, an anti-jump device or even no anti-jump device, easy to derail when pushing and pulling, very unsafe.

Shake 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 slide rail, if the quality of the sliding door is good, the gap between them is almost zero, so that there will be no vibration when sliding, smooth and smooth. Therefore, the close combination of the upper pulley and the slide rail determines the smoothness of its sliding.

Bottom wheel

Only the bottom wheel with large load-bearing force can ensure its good sliding effect and long service life. The high-grade sliding door is made of carbon glass fiber, with internal ball, with non-lubricating ester, poor pulley is often made of engineering plastics or organic plastics, bearing capacity is small, start to use may not be a big problem, but a long time is easy to deform, affecting the effect of pushing and pulling

Panel style

Partition: As a partition door, most of them are more transparent panels, which can make the space more open, take into account the decorative effect, and match the overall room style.

Cabinet door: The material is wood, glass, mirror and other, the height of the glass door should not exceed 2.5 meters, the bedroom should not choose the mirror door. Plate sliding door is simple and generous, good safety, in addition, there are shutter series sliding door, plate sliding door.

Stop and stop device

The stop block is generally made of steel, but the durability of the good steel will be stronger, the steel is not good, and the displacement will occur after a long time collision, so that the sliding door can not stop in place. In fact, the metal has a fatigue period, it is easy to deformation after a long time of work, and the stop block made of copper is corrosion resistant and can remain stable for a long time, so you can try to choose such a material.
