Aluminum alloy doors and windows are generally chosen for decoration now, because this information is not only beautiful and durable, so it is liked by vast owners, but many owners do not have a special understanding of aluminum alloy doors and windows, and the quality of aluminum alloy doors and windows products produced by different manufacturers is generally different, so it is more difficult to select aluminum alloy doors and windows, after all, aluminum for household use. What are the buying skills of alloy doors and windows? 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 profile (main material, auxiliary material), glass (toughened glass) and hardware fittings, etc. The general decoration owners often pay more attention to the thickness of main material, auxiliary material and glass when choosing doors and windows. The requirement of hardware fittings is not very high, which is unscientific. In fact, the requirement of the state on 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 alloy is qualified. Only a part of the merchants are not qualified when ordering aluminium alloy. The small edition suggests that when we choose aluminium alloy doors and windows, we must have vernier calipers to measure the thickness of aluminium alloy. The hardware fittings related to wall thickness and Glass-Aluminium alloy doors and windows (screw, plywood, pulley, etc.) Requirements should also understand that stainless steel hardware fittings must be better than aluminum fittings, and pulleys are load-bearing, so it is recommended to choose double pulleys, such as high product quality, good wear resistance, long life, push-pull smooth and not easy to damage.
2. Functions:
Selection of 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 the hollow layer containing dirt, affecting the beauty, the function of doors and windows because of the different scope of application, the emphasis is also different, single general consideration of strength, sealing and so on, strength is primarily reflected in the selection of profiles for doors and windows. On the other hand, whether he can withstand ultra-high pressure or not; the sealing performance is reflected in the structure of doors and windows, and whether the inner 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 profile series and specifications, processing Jerry work, door frame corner and other orientations can not be spliced flat, sometimes even show large gaps, we should pay special 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 generally use aluminium profiles made from recycled aluminium and scrap aluminium containing many impurities, whose wall thickness is generally 0.6-0.8 mm left. Right, both tensile strength and elasticity are much lower than the relevant provisions of the state. High-quality aluminium materials are generally about 1.2-1.4 mm, and even some high-end brands have better stability in wall thickness of 1.6, 1.8, 2.0 mm, of course, the price will not be low.
