Tips for buying sliding doors

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

Thickness
If glass or silver mirror is used as the door core, it is generally 5mm thick; If you use wooden boards as the door core, it is best to use a thickness of 10mm. In order to save material costs, some manufacturers use thinner wood boards (8mm or even 6mm) instead. The wooden board that is too thin will appear frivolous and shaky when pushed and pulled, and the stability is poor, and after a period of use, it is easy to warp and deform, and the guide rail is stuck, resulting in unsmooth pushing and pulling, which affects the normal use.

Lacquered finish
The paint surface is double-layer branded before spraying and transferring, that is, the surface is dusted and impurities are soldered, which increases the adhesion of the paint surface, and the paint surface never falls off, while the profiles of some small manufacturers are simply branded, or even not branded, so the paint surface is easy to fall off and the texture is not clear.
The surface of the profile of the manufacturer of large sliding doors is processed by the company itself, and then processed by imported advanced technology, and the paint surface of the product is smooth and delicate, uniform and full, and the texture is clear. Small sliding door manufacturers are wholesale from the profile factory finished products with color profiles, the surface can not be treated by themselves, the color is single, the door color is not interchangeable, such as the profile scratches in transportation or installation, the color of the original door does not match when replenishing, and the color difference is large.

Plate
The wooden boards (mainly fiberboard and particleboard) used to make sliding doors are wood-based panels, and the adhesives used contain harmful substances such as formaldehyde. There are many wall cabinet door manufacturers on the market, most of their wood boards are produced in China, and even use poor boards, and many boards have excessive formaldehyde content, which emits indoor and pollutes the environment. In the cold season in the north, when doors and windows are closed, the impact on the health of consumers is greater.

Pulley material
The pulley is the most important hardware component in the sliding door, and the material of the pulley on the market is plastic pulley, metal pulley and glass fiber pulley. Metal pulleys are strong, but they are prone to noise when in contact with the track. Carbon fiberglass pulley, including roller bearings, smooth push and pull, wear-resistant and durable, box-type closed structure is effective dustproof, more suitable for the northern area with large wind and sand, and two anti-jump devices ensure safety and reliability when gliding. The wheels of some low-grade sliding doors are made of organic plastics, which are easy to wear and deform, and the time of pushing and pulling will be undulating, and the open wheel structure is easy to enter the dust and wear the internal bearings, and it is difficult to ensure that the push and pull are flexible, and an anti-jump device even does not have an anti-jump device, which is easy to derail when pushing and pulling, which is very unsafe.
Shake the sliding door in the vertical direction of the slide rail, the smaller the degree of shaking, the better its stability. When shaking, pay attention to observe the upper pulley and the upper slide rail, if the quality of the sliding door, the gap between it is almost zero, so that there will be no vibration feeling when sliding, smooth and smooth. Therefore, the close combination of the upper pulley and the slide rail determines the smoothness of its sliding.

Bottom chakra pros and cons
Only the bottom wheel with super load-bearing capacity can ensure its good sliding effect and long service life. High-grade mobile sliding door is made of carbon glass fiber, with balls inside, with non-dry lubricating ester, poor pulleys are often made of engineering plastics or organic plastics, the bearing capacity is small, and it may not be a big problem to start using, but it is easy to deform after a long time, affecting the effect of pushing and pulling

Plate 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 living room style.
Cabinet door: the material is wood, glass, mirror and others, the height of the glass sliding door should not exceed 2.5 meters, and the bedroom should not choose the mirror sliding door. The plate sliding door is simple and generous, with good safety, and there are also louver series sliding doors and plate sliding doors.

Stop-stop device
The stop block is generally made of steel sheet, but the durability with good rigidity will be stronger, and the rigidity is not good, and the displacement will occur after a long time of collision, so that the sliding door can not stop in place. In fact, metals have fatigue periods and are easy to deform after a long period of work, while the stop block made of copper is corrosion-resistant and can remain stable for a long time, so you can choose such a material as much as possible.
