Aluminum doors and windows have a short service li

  • Detail

Building is a long-term project, which requires doors and windows to have a long enough service life. During the service life, except for a few vulnerable parts, the main structure and main accessories are not allowed to be damaged, deformed, obvious color change on the surface, fade and lose light

aluminum alloy doors and windows have become the main building door and window products in China because of their light weight, high strength, good performance, strong decoration, economy and durability. However, at present, the quality of aluminum alloy doors and windows in the market is uneven, and the phenomena of poor sealing performance, uneasy switching, air and rain leakage and glass cracking are common. Poor quality aluminum alloy doors and windows are easy to scrape, bump and age the sliding part or glass when encountering strong winds and external forces, and the service life of the products is short

building is a long-term project, which requires that doors and windows must have a long enough service life. During the service life, except for a few vulnerable parts, the main structure and main accessories are not allowed to be damaged, deformed, corroded, aged, and the surface is obviously discolored, faded, and lost light

let's understand the main factors affecting the durability of doors and windows

1. Profile

after good surface treatment, aluminum profile has good resistance to atmospheric corrosion, is not afraid of humidity, is not afraid of sunlight, does not deform at high temperature, does not embrittle at low temperature, does not burn, lightning protection, lasting stability and other capabilities, and is suitable for all kinds of climatic environments. The quality of profiles directly determines the quality of doors and windows. Doors and windows produced by inferior profiles have low strength and are very easy to change color and deformation

profile materials mainly include: aluminum profile used for high-quality aluminum alloy doors and windows, thickness, strength and oxide film, etc., which should comply with the relevant national standards. The wall thickness should be more than 1.2mm, the tensile strength should reach 157n per square millimeter, the yield strength should reach 108n per square millimeter, and the oxide film thickness should reach 10 microns

2. The configuration of doors and windows

hardware is the main factor that determines the quality of the whole window. The quality of door and window hardware accessories largely determines the service life of doors and windows. It can be said that door and window hardware is the core of the whole door and window, including handles, lock cores, hinges, etc., and every component is important

main factors affecting the service life of door and window hardware fittings:

humidity: as the moisture in the air condenses into a liquid water film, which is a necessary condition for the formation of corrosive primary cells, when the humidity reaches a certain critical value, a water film is formed on the surface, and the corrosion rate intensifies

temperature: when it is high temperature and high humidity, the increase of temperature accelerates the corrosion. The longer the humidity time is, the more serious the corrosion is

atmospheric quality: under normal circumstances, only oxygen in the air will corrode metals, but with the development of world industrialization, harmful gases and dust in the air have also increased significantly, such as carbon dioxide, sulfur dioxide and other gases produced by the combustion of coal and gasoline

corrosion prevention of hardware is very important. In case of corrosion, it will affect the function and performance of doors and windows, and its service life will be greatly reduced, thus affecting the energy-saving effect of doors and windows

3. The level of processing

the level of production equipment and technology determines whether the overall performance of doors and windows is excellent. High quality aluminum alloy doors and windows, fine processing, smooth tangent, consistent angle, good sealing performance, and easy switching

poor quality aluminum alloy doors and windows, blindly select aluminum profile series and specifications, process rough, use sawing instead of milling, do not install according to requirements, and have poor sealing performance. Not only do they leak air and rain and have glass cracking, but also when encountering strong winds and external forces, it is easy to scrape or bump the push-pull part or glass, and damage objects and hurt people. Therefore, when purchasing aluminum doors and windows, we must choose high-quality doors and windows. Of course, we also need later maintenance and repair

Xiangyue doors and windows has always adhered to the rigorous and innovative concept. While introducing the technical essence of modern European doors and windows, it integrates the Oriental aesthetic concept, constantly weeding out the old and bringing forth the new, and develops high-end products and top-level services rich in Oriental life elements! High end door and window products, derived from high-quality profiles and accessories, should have careful design and fine processing to ensure the excellent quality of doors and windows
