Aluminum alloy is usually used for decoration of doors and windows, because this kind of information is not only beautiful and durable, so it is liked by vast owners, but many owners do not have a special understanding of aluminium alloy doors and windows, and the quality of aluminium alloy doors and windows produced by different manufacturers is generally different, so the selection of aluminium alloy doors and windows is very important. Aluminum alloy doors and windows are more laborious. What are the skills of selecting and purchasing aluminium alloy doors and windows for household use? How about the inspection methods of aluminium alloy doors and windows? Let's get to know it with Xiaobian.

Household Aluminum Alloy Doors and Windows Purchasing Skills:

1. Materials:

The material selection of doors and windows generally includes: aluminium profiles (main materials, auxiliary materials), glass (toughened glass) and hardware accessories, etc. The general decoration owners often pay more attention to the thickness of main materials, auxiliary materials and glass when choosing doors and windows. The requirements for hardware accessories are not very high, which is not scientific, in fact. The requirement of our country about aluminium alloy doors and windows is standardized. Generally, the wall thickness of aluminium alloy doors and windows should not be less than 1.2mm. Generally, the thickness of aluminium materials of the merchants is qualified. Only a part of the merchants are not qualified when ordering aluminium materials. The small edition suggests that we must have vernier calipers to measure aluminium when choosing aluminium alloy doors and windows. Material thickness, related to wall thickness and Glass-Aluminium alloy doors and windows hardware accessories (screw, hinge, pulley, etc.) requirements should also be understood, stainless steel hardware accessories must be better than aluminum accessories, and pulley is a load-bearing, so it is recommended to choose double pulley, such product quality is high, wear resistance is good, long life. Push and pull smoothly and not easily damaged.

2, function:

Choosing aluminium alloy doors with mosaic glass, especially hollow glass planned products, must pay attention to its sealing function. If the sealing is not good, it will lead to dirt and dirt in the hollow layer, affecting the beauty. The functions of doors and windows are different because of different application scope, and the emphasis is also different. Strength and sealing are considered only in general. The strength is mainly reflected in the material selection of the profiles of doors and windows, whether he can withstand ultra-high pressure, and the sealing is reflected in the structure of doors and windows, whether the internal fan and frame structure of doors and windows are tight.

3, processing quality:

High-quality aluminium door, fine processing, welding is exquisite, especially some splicing parts are very flat, and poor quality aluminium door and window, blindly select Aluminium Profiles Series and specifications, processing jerry-built materials, doorframe corner and other directions can not be spliced flat, and sometimes even show large gaps, we should be special when choosing and purchasing. Pay attention to check whether there are welding defects, such as open welding, leakage welding and other phenomena.

4, price:

Although the price of aluminium alloy doors and windows is directly related to the price of aluminium ingots, the price realized by doors and windows in the same period is relatively stable. Generally speaking, the price of high-quality doors and windows is about 30% higher than that of low-quality doors and windows. Low-quality doors and windows are usually manufactured from recycled aluminium and scrap aluminium containing many impurities. The wall thickness of aluminium profiles is generally about 0.6-0.8 mm. The tensile strength and elasticity of aluminium profiles are much lower than the relevant national regulations. High-quality aluminium profiles are generally about 1.2-1.4 mm. Even some high-end brands have better stability with wall thickness of 1.6, 1.8 and 2.0 mm. Of course, the price will not be low.
