When choosing aluminum alloy doors and windows, various factors should be considered comprehensively. Here are some small experiences that I hope will be helpful to you. How to choose aluminum alloy doors and windows, l) characteristics of aluminum alloy doors and windows compared with steel wood doors and windows, aluminum alloy doors and windows have the following advantages: l) light weight and high strength. The density is only l/3 of steel. 2) good sealing performance. Sealing performance directly affects the use function and energy consumption of doors and windows. The sealing performance includes four aspects: air tightness, water tightness, heat insulation and sound insulation. 3) good durability, easy to use and maintain. Aluminum alloy doors and windows do not rust, fade, fall off, almost no maintenance, and the service life of spare parts is extremely long. 4) elegant decoration. The surface of aluminum alloy doors and windows is artificially oxide film and colored to form a composite film layer. This composite film is not only corrosion-resistant and wear-resistant, but also has certain fire resistance and extremely high gloss. Aluminum alloy doors and windows are light in weight and precise in processing and assembly, so they are light and flexible in opening and closing without noise. It is not uncommon for aluminum alloy materials to deform doors and windows, push and pull, etc. Consumers should note the following points when purchasing: Take a look at the material. There are six main aspects of material and materials for reference: 1. Thickness: aluminium alloy sliding door there are 70 series and 90 series, and 70 series can be used for aluminium alloy sliding door inside the house. The number of series indicates the number of millimeters of the door frame thickness construction dimension. Aluminium alloy sliding window has four types: 55 series, 60 series, 70 series and 90 series. Series selection should be based on the size of the window hole and the local wind pressure value. The aluminium alloy sliding window used as a closed balcony shall not be less than 70 series. Tensile strength: the tensile strength should reach 157 newtons per square millimeter, and the yield strength should reach 108 newtons per square millimeter. When purchasing, you can use your hands to bend the profile moderately, and you should be able to recover after loosening your hands. If the color difference is obvious, it is not suitable to buy. ⒋ flatness: check the surface of aluminum alloy profile, there should be no depression or bulging. Gloss: aluminum alloy doors and windows avoid choosing profiles with open bubbles (white dots) and Ash (black dots) on the surface, as well as obvious defects such as cracks, burrs and peeling. Oxidation degree: oxide film thickness should reach 10 micron. When purchasing, you can draw the profile surface lightly to see if the oxide film on the surface can be wiped off.
Personal recommend chuangye. When I was just doing doors and windows before, I didn't know which brand to choose. High-end brands are expensive, while low-end brands are cheap but the quality cannot be guaranteed. My friend recommend Chuangye. He didn't have much confidence at first. Later, it was really good to try out a business, which was better than those sold in nearby door and window stores, because what they did was high-end or low-end, chuangye is in the middle and high-end market. The price of doors and windows of Chuangye is not expensive in the market and the quality is guaranteed. The after-sales service is also very good and trustworthy.
