thickness
If the glass core or silver Mirror is used as the door core, it is generally 5mm thick; if the wood core is used as the door core, it is best to use 10mm thickness. Some manufacturers use thinner wood boards (8mm or even 6mm) instead of material cost savings. The board is too thin, it is swaying and swaying, and the stability is poor. After using it for a period of time, it is easy to warp and deform, and the card guide rails cause the sliding to be unsmooth and affect the normal use.
Paint surface
The paint surface is double-layered in the spray transfer, that is, the surface dust removal and the impurity removal, which increases the adhesion of the paint surface, the paint surface never falls off, and the profiles of some small manufacturers are simply baked. It is not even baked, so the paint surface is easy to fall off and the texture is not clear.
The surface of the manufacturer of the large sliding door is processed by the company itself, and then processed by imported advanced technology. The paint surface is smooth, delicate, even and full, and the texture is clear. The manufacturer of small sliding doors sells finished products with color profiles from the profile factory. The surface can not handle it by itself. The color is single and the color of the door is not interchangeable. If the profile is scratched during transportation or installation, the color of the original door and the original door are not Match, big color difference and other issues. For example, manufacturers such as Sophia, Ocean Gate, Nature Doors and Windows, and Top Solid are very careful in the processing of paint finishes.
Plate
The wooden boards (mainly fiberboard and particleboard) that are used for sliding doors are all wood-based panels, and the adhesives used contain harmful substances such as formaldehyde. At present, many of the wall Cabinet manufacturers on the market, most of which are produced in China, even using poor quality plates, many of which have excessive formaldehyde content, which is distributed indoors and pollutes the environment. In the cold season in the north, when the doors and windows are closed, the health of consumers is more affected.
Material of the pulley
The pulley is the most important hardware component in the sliding door. At present, the pulleys on the market are made of plastic pulleys, metal pulleys and fiberglass pulleys. Metal pulleys are strong, but they are prone to noise when in contact with the track. Carbon fiberglass pulley with roller bearing, smooth sliding and durable wear-resisting. The box-type closed structure is effective against dust. It is more suitable for the northern part of the wind and sand. Two anti-jump devices ensure safe and reliable when sliding. The wheels of some low-grade sliding doors are made of organic plastic, which are easy to wear and deform. When the time is long, the height of the wheels is undulating. The structure of the open wheel is easy to enter the dust and wear the inner bearing. It is difficult to push and pull flexibly. One anti-jump device does not even have an anti-jump device. It is easy to derail when pushing and pulling, it is very unsafe.
Find out the warranty period
The poorly-selling sliding door manufacturers, in order to take orders before the sale, may make a promise to the customer's warranty, wait until the customer finds problems in the use of the need for repair and other after-sales service, or listen to it, or push the three, or casually, all kinds of services The problem is exposed. Therefore, it is recommended that consumers should fully understand the strength of the manufacturer before ordering, and find out the warranty period. After the product is installed, ask for the product warranty card. After all, sliding doors are also expensive household durable consumer goods.
