Aluminum alloy sliding door shopping guide

  • Detail

Sliding doors originated in China and spread to Korea and Japan through Chinese culture. From the word meaning: push and pull the door; In terms of materials, there are wood, metal, organic and inorganic materials; In terms of use: it is used for bookcases, wall cabinets, bedrooms, living rooms and doors of exhibition halls. Sliding doors originated in China and spread to Korea and Japan through Chinese culture. There is no way to verify the specific time, but you can see scattered sliding doors in some ancient Chinese paintings, such as the landscape paintings of the Song Dynasty

at first, the sliding door was only used for the sliding door of the wardrobe in the bedroom or dressing room. However, with the development of technology and the diversification of decoration means, the function and scope of use of the sliding door are expanding from the traditional plate surface, to glass, cloth, rattan, aluminum alloy profiles, from sliding door, folding door to partition door. In this case, the use of sliding doors began to become diverse and rich. In addition to the most common partition doors, sliding doors are widely used in bookcases, wall cabinets, living rooms, exhibition halls, sliding doors, etc


whether it's a square meter bathroom or an irregular storage room, as long as the sliding door is replaced, no matter how narrow the space is, it will not be wasted. The folding sliding door can even be 100% opened, accounting for no space. From the perspective of use, the sliding door undoubtedly greatly facilitates the space division and utilization of the room, and its reasonable push-pull design meets the compact order and rhythm that modern life stresses. In terms of taste, the push-pull glass door will make the room appear lighter, and the segmentation, concealment and so on are so simple but still change. Today, when we advocate getting close to nature, we can install a smooth, quiet, transparent and bright sliding door on the balcony to enjoy the sunshine and scenery


if glass or silver mirror is used as door core, 5mm thick is generally used; If wood is used as the door core, 10mm thickness is the best. In order to save material costs, some manufacturers use thinner wood (8mm or even 6mm) instead. The board is too thin. It looks flighty and shaking when pushed and pulled, and its stability is poor. After using it for a period of time, it is very easy to warp and deform, and jam the guide rail, resulting in the unsmooth push and pull, which affects the normal use


the paint has been double branded before spraying and transfer, that is, surface dedusting and impurity removal branding, which increases the adhesion of the paint, and the paint will never fall off. However, some small manufacturers' profiles are simply branded, or even not branded, so the paint is easy to fall off and the texture is not clear

the profile surface of the manufacturers of large sliding doors is processed by the company itself, and then processed with imported advanced technology. The product has smooth and delicate paint, even and full, and clear texture. The manufacturers of small sliding doors wholesale finished colored profiles from the profile factory. The surface cannot be processed by themselves. The color is single, and the color of the door type is not interchangeable. For example, the profile is scratched during transportation or installation, the color of the replenishment does not match the color of the original door, and the color difference is large. For example, Sofia, dayanghaomen, nature doors and windows, dinggu and other manufacturers are very meticulous in paint treatment


the wood boards (mainly fiberboard and particleboard) used as sliding doors are all man-made boards, and the adhesives used contain formaldehyde and other harmful substances. At present, many wall cabinet door manufacturers in the market mostly produce their boards in China, and even use coarse boards. Many boards 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, it will have a greater impact on the health of consumers

pulley material

pulley is the most important hardware component in sliding doors. At present, there are three kinds of pulley materials in the market: plastic pulley, metal pulley and glass fiber pulley. The metal pulley has high strength, but it is easy to produce noise when in contact with the track. The carbon glass fiber pulley contains roller bearings, which are smooth to push and pull, wear-resistant and durable. The box closed structure is effective in dust prevention. It is more suitable for northern areas with heavy sandstorms. Two anti jump devices ensure safety and reliability when sliding. The wheels of some low-grade sliding doors are made of organic plastic, which are very easy to wear and deform. After a long time of pushing and pulling, they will rise and fall. The open wheel structure is easy to enter dust and wear the internal bearings, so it is difficult to ensure the flexibility of pushing and pulling. An anti jump device even has no anti jump device, so it is easy to derail when pushing and pulling, which is very unsafe

find out the warranty period

the sliding door manufacturers with poor strength may make pleasant warranty promises to customers in order to receive orders before sales. When customers find problems in use and need after-sales services such as maintenance, they may turn a deaf ear to them, push and hold back, or deal with them casually, and all kinds of service problems will be exposed. Therefore, it is suggested that consumers should fully understand the strength of the manufacturer before ordering, find out the warranty period, and ask for the product warranty card after the product is installed. After all, sliding doors are also expensive household durable consumer goods
