Aluminum alloy doors and windows are a common door and window product used in the 1990 s in our country. Currently, they are still in use in southern cities. Now the hottest one is upgraded and improved by this kind of doors and windows, the ratio of using aluminum alloy doors and windows in southern cities is very high, so which brand of aluminum alloy doors and windows is among many brands
Aluminum alloy doors and windows are a common door and window product used in the 1990 s in our country. Currently, they are still in use in southern cities. Now the hottest one is upgraded and improved by this kind of doors and windows, the ratio of using aluminum alloy doors and windows in southern cities is very high, so which brand of aluminum alloy doors and windows is better among many aluminum alloy doors and windows brands?
At present, the brands with good sales in the market mainly include Guangdong fengaluminum, guangaluminum, Xinhe, Guangya, Jianmei and other famous domestic brands of aluminum alloy doors and windows. Among many brands of aluminum alloy doors and windows, these are good ones. Is there any difference between brand aluminum alloy doors and windows and miscellaneous aluminum alloy doors and windows? Consumers who don't know will ask, they are all made of aluminum alloy. What is the difference between good brands and no brands? There are also differences in prices.
Let's put it this way, brand-good aluminum alloy doors and windows are different in oxide film, aluminum wall thickness and aluminum composition. Brand-good aluminum alloy doors and windows use native aluminum ingot extrusion, however, aluminum alloy doors and windows with low prices of miscellaneous brands are extruded by aluminum waste, and the hardness strength is not as good as that of original aluminum ingot, that is, there is no strong brand aluminum alloy doors and windows.
Next, I will teach you how to distinguish the advantages and disadvantages of aluminum profiles. Only by knowing these can consumers avoid being cheated and disputes as much as possible when purchasing. In fact, it is not difficult for careful consumers to find out, inferior aluminum profiles have the following four characteristics:
1. Oxide film thickness is thin. The national standard stipulates that the thickness of building aluminum profile oxide film should not be less than 10um (micron). The thickness is not enough, and the surface of aluminum profile is easy to rust and corrode. Some aluminum profiles without production names, factory addresses, production licenses and certificates in the sampling inspection are only 2 to 4um in thickness at oxide film, and some even do not have oxide film. According to experts' estimation, for every 1um oxide film thickness reduction, the power consumption cost per ton of profiles can be reduced by more than 150 yuan.
2. The chemical composition is unqualified. Adding a large amount of miscellaneous aluminum and aluminum waste aluminum profiles can greatly reduce the cost, but it will lead to unqualified chemical composition of building aluminum profiles, seriously endangering the safety of construction projects
3. Reduce the wall thickness of the profile. 90 series sliding window type, according to national standards, its aluminum profile wall thickness is not less than 1.4mm, and some Guangdong products are only 0.6 to 0.7mm. 46 Series ground bullet door type, the minimum wall thickness of aluminum profiles used in national standards is not less than 1.62mm. In the sampling inspection, some products in Guangdong are only 0.97 to 1.18mm.
4. Inferior aluminum profiles greatly reduce the sealing time, reduce the loss of chemical reagents and reduce the cost, but the corrosion resistance of profiles is also greatly reduced.
Of course, this is just some methods to identify the advantages and disadvantages of aluminum profiles. If consumers want to know more about the purchase and maintenance of aluminum alloy profiles, they can go to the information column of windows and doors of easy window network to have a look, I believe it will help you. If you don't know much about aluminum alloy doors and windows, you 'd better choose brand aluminum alloy doors and windows, such as Phoenix aluminum alloy, strong beauty, guangaluminum, guangya and other famous brands.
Nowadays, through the improvement and upgrading of technology, many manufacturers that originally produced aluminum alloy profiles have developed and produced them one after another., this kind of doors and windows is more superior than aluminum alloy doors and windows. It is an energy-saving and environment-friendly door and window product, which is very popular and practical in northern cities at present.
