Sliding door purchase knowledge
1, the 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 2.8 meters, and it will not shake, it is more stable, if the wall thickness is less than 1.2, such as some only 0.8mm or 1.0mm is the highest Can only be done within 2 meters, 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.
Border profile surface treatment is divided into three categories: alkaline sand, spray paint, electrophoresis. The electrophoresis process is the best, and the other two are easier to fade and paint out. The surface treatment of electrophoresis is relatively smooth. It is easy to see that the black walnut color of the border profile, the electrophoretic process of the surface of the black walnut pattern is more delicate, uniform color, the paint pattern is more vague, and the distribution is uneven, especially in the middle of the profile recessed The paint in that place is particularly thick and the pattern is more blurred.
Profile composition: sub-aluminum-magnesium alloy, carbon steel, aluminum alloy three. The aluminum-magnesium alloy material is an exclusive material for the aviation field. It has the advantages of light weight, high strength, oxidation resistance, and corrosion resistance. However, its profile price is also higher than that of common profiles, but aluminum alloy doors and windows are more likely to be corroded. , The intensity is not high. Some js are made of low-quality cold-rolled steel sheet shaped carbon steel profiles made of door edge, the thickness of the profile is less than 1mm, strength and anti-oxidation procedures are not ideal.
2, roller: generally installed in the bottom 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. The good sliding door adopts the imported light steel ball bearing. The bearing is marked with the manufacturer and the product model. The bearing is marked on the edge. The outside steel sleeve should also have A sign of your own company. Although there are bearings that are poor, there is no manufacturer's name and other signs. Such bearings have poor wear resistance and short service life. The poor roller is almost the same as the good one when it is just installed (the average person does not feel it), but there are obvious differences after six months. 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.
There are several types of bearing outer cladding: one is glass fiber composite material, one is ordinary plastic or rubber with poor wear resistance. The anti-aging and wear resistance of glass fiber is much better than that of plastic and rubber, and the use and time are also long. Does not affect the sliding of the sliding 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 takes.
3, look at the brand: Many dealers are now the name of a certain country import, a certain country technology, distinguish between true and false, the easiest to just check the Internet. Brand sliding doors have independent websites and related information such as the distribution addresses of each region. When searching with google, Baidu, etc., there are also relevant information of the brand, such as the brand buying information (if any, you can compare the distribution in the region). The price of the business is higher or lower than other places. Generally, the self-employed and self-made materials of certain countries can't find any relevant information on the website. The visibility of the brand can be seen in one shift.
4, after-sales service: brand sliding door in the sale of sliding doors will have a relevant quality warranty card, and specify the scope of the warranty and time limit. Some self-employed households will make indiscriminate promises and will not issue related warranty cards. Future maintenance will be very troublesome.
5. Whether the procedures are complete: The general brand js has the power of attorney of the head office, a copy of the business license, legal person qualifications, etc. The high-grade brands have relevant inspection reports (such as the wheel inspection report, sliding door inspection report, etc.) The quality of the sliding door can also be seen indirectly through the inspection report. Many shopkeepers who are branded with foreign brands must be counterfeit if they do not have authorization. Others can look at whether or not the trademark has been registered. How can a company whose trademark is not registered be a foreign brand?
The other thing is to look at the feeling, a good sliding door pulls up smoothly, no noise, no impurities, calm but smooth, poor, there is noise, there is a kind of bounce, you can pull a few doors to see, in addition to look js Whether the store is clean and tidy and whether the service is warm and professional. A js that is not even clean in the store can't make high quality sliding doors for you.
