Aluminum alloy doors and windows are believed to be used by many families. They have good sealing performance, do not rust, fade, do not fall off, and have a long service life. Therefore, they have always been loved by people. There are a lot of aluminum alloy doors and windows on the market at present, and the quality is also mixed. How to buy aluminum alloy doors and windows for home use? What are the installation process and inspection methods of aluminum alloy doors and windows? Let's follow the editor to understand.

How to choose and buy household aluminum alloy doors and windows:

1. Data:

Data selection of doors and windows generally includes: aluminum profiles (main materials, auxiliary materials), glass (toughened glass) and hardware accessories, etc. when selecting doors and windows, the general decoration owners often pay more attention to the wall thickness of main materials and auxiliary materials and the thickness of glass, while the requirements for hardware accessories are not very high, which is unscientific. In fact, the national requirements on aluminum alloy doors and windows are standardized Generally, the wall thickness of aluminum alloy doors and windows shall not be less than 1.2mm, and the thickness of aluminum materials of general merchants is qualified. As long as some merchants are unqualified when ordering aluminum materials, Xiaobian advocates that we must have vernier caliper to measure the thickness of aluminum materials when selecting aluminum alloy doors and windows, which are related to wall thickness and hardware accessories (screws, hinges, pulleys, etc.) of glass aluminum alloy doors and windows Requirements should also be understood, stainless steel hardware accessories are certainly better than aluminum accessories, and pulley is load-bearing, so we advocate the selection of double pulley, such products have high quality, good wear resistance, long life, smooth push and pull, not easy to damage.

2. Function:

When selecting aluminum alloy doors with inlaid glass, especially the products planned with insulating glass, we must pay attention to its sealing function,. If the sealing is not good, it will lead to the hollow layer containing dirt and filth, which will affect the beauty. The function of doors and windows depends on the scale of application, and the emphasis is also different. The strength is mainly reflected in the material selection of door and window profiles, and whether they can accept ultra-high pressure; the sealing performance is reflected in the structure of doors and windows, whether the inner leaf of doors and windows is close to the frame structure.

3. Processing quality:

High quality aluminum alloy doors are precise in processing and pay attention to welding, especially some splicing parts are very flat. However, for defective aluminum alloy doors and windows, aluminum profile series and standards are blindly selected, and the processing is shoddy. The corner of the door frame can not be spliced flat, sometimes even with large gaps. When we purchase, we should pay special attention to check whether there are welding defects, such as open welding and missing welding And so on.

4. Price:

Although the price of aluminum alloy doors and windows is directly related to the price of aluminum ingot, the price realized by doors and windows in the same period is still relatively stable. Generally speaking, the price of high-quality doors and windows is about 30% higher than that of defective doors and windows. Aluminum profiles made of recovered aluminum and waste aluminum containing many impurities are generally used for defective doors and windows, and the wall thickness is generally 0.6-0.8mm Right, both the tensile strength and elasticity are much lower than the relevant national regulations. High quality aluminum materials are generally about 1.2-1.4mm, and even some high-end brands have better stability with wall thickness of 1.6, 1.8 and 2.0mm. Of course, the price will not be low.

5. Appearance:

Interior decoration owners in the purchase of doors and windows products, generally attach great importance to the appearance of the products and decorative pictures of glass, but ignore the composite film on the surface of doors and windows. This composite film is composed of artificial oxide film coloring, with corrosion resistance, wear resistance, high gloss, etc., and also has a certain fire prevention function. Therefore, it must be carried out more when purchasing aluminum alloy doors and windows products In comparison, the glass process varies from person to person, according to their own preference.
