How to identify sliding door
The appearance of glass, panel, and cloth art, and a variety of sliding doors make consumers choose one more choice for home decoration. The sliding door has a strong decorative effect, but consumers must keep their eyes open when they are shopping, because poor sliding doors cannot be moved after a period of use. So share the identification skills:
1 border material
The thickness of the border profile is generally 1.2mm-1.5mm, so that the maximum height of the sliding door can be 2.8m, and it will not shake, it is more stable, if the wall thickness is less than 1.2mm, such as some only 0.8mm or 1.0mm The maximum can only be less than 2m, too high will shake, prone to problems. The thickness determines the price of the profile and the cost is relatively high, which also determines the firm performance of the sliding door.
2. Roller
Mounted on the bottom or upper part of the sliding door. One wheel is roughly divided into two parts, one is the bearing and the other is the bearing outer layer.
The quality of the bearing plays a key role in the durability of the sliding door. Good sliding doors are made of imported lightweight steel ball bearings. When the poor roller is installed, the effect is almost the same as that of the good one. (General people do not feel it), but After six months, there are obvious differences. Poor roller wear resistance is very poor, easy to emit noise, pull up more rigid, easy to beat. Generally, the pulley is hidden, and it is better not to see the pulley on both sides of the door. A good bearing and overcladding can allow the sliding door to slide more than 100,000 times to ensure long-term use. Poor one cannot guarantee how long it will take. Some sliding doors have very smooth sliding bottom wheels, but if you look closely, you will find that the bottom wheels have a greasy feel, which means that the smoothness is achieved by the bottom wheel grease. This bottom wheel is not only easy to contaminate the dust, but once the grease is dry , it will produce blocking phenomenon, affect the sliding effect.
Stop block
When the door is closed when the ground is uneven, when the door hits the wall, it will generate a rebound force, which will cause the door to move sideways and cannot stop smoothly. At this time, the “stopping block†gadget can play the role of anti-slip. "Break stop blocks" are usually made from tough steel sheets, which have good durability and are not easily deformed. If the steel is not good, it will shift after a long period of collision, so that the sliding door cannot be stopped in place. Metals also have a fatigue period and are prone to deformation when used for a long time. However, the "stop block" formed by the copper block is corrosion-resistant and stable for a long time.
4. Door gap
In order to ensure that the two doors are staggered and closed, all the sliding doors will have a certain interval. Generally, the outer pulley needs an interval of 15 mm. This interval affects the sealing of the sliding door and increases the chance of dust intrusion. Although most products have tops added, the size of the tops and gaps are still very much related. When purchasing, try to choose products with small intervals and tops.

5. Environmental issues
Wood grain and other color products are often glued up. When buying, you can smell whether the glue used has a pungent odor.
6. After-sale service
The brand sliding door will have relevant quality warranty card when selling the sliding door, and indicate the scope and time limit of the warranty. Some self-employed households will make indiscriminate promises and will not issue related warranty cards. Future maintenance will be very troublesome.
7. Is the procedure complete?
General brands have authorizations from the head office, a copy of the business license, legal personality, etc. The high-grade brands have relevant inspection reports (such as wheel inspection reports, sliding door inspection reports, etc.), and can also be indirectly passed through inspection reports. See the quality of the sliding door. Many shopkeepers who are branded with foreign brands must be counterfeit if they do not have authorization.
