1. The characteristics of aluminum alloy doors and windows Compared with steel and wood doors and windows, aluminum alloy doors and windows have the following advantages: 1) Light weight and high strength. The density is only 1/3 of steel. 2) good sealing performance. Airtight performance directly affects the use of doors and windows function and energy consumption. 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, do not fade, do not fall off, almost no maintenance, spare parts service life is very long. 4) Decorative effect is elegant. The surface of aluminum alloy doors and windows has artificial oxide film and coloring to form a composite film layer. This composite film is not only corrosion-resistant, wear-resistant, has a certain degree of fire resistance, but also has high gloss. Aluminum alloy doors and windows due to light weight, processing and assembly precision, accurate, and thus open and close light and flexible, no noise. However, in actual use, it is not uncommon for aluminum alloy materials to deform doors and windows and push and pull. This requires consumers to buy aluminum alloy doors and windows should be paid attention. Consumers must keep in mind the following six aspects of the purchase guide: the identification of 1. signs is regular or manufacturers with production licenses, and the product signs are marked on the obvious parts of their aluminum alloy products, including: manufacturer name or trademark, Product name, product model or mark, manufacturing date or number. The packing box shall be marked with the words and signs of "moisture-proof", "handle with care" and "upward. Such as Kemet aluminum profiles do very well in this regard. 2. surface quality The quality of doors and windows directly affects the decorative effect of the entire wall after installation. When checking the surface quality of doors and windows, the following aspects should be paid attention to: A. There should be no obvious damage to the decorative surface of doors and windows. It means that the protective film on the surface of doors and windows should not have traces of scratches and scratches. B, doors and windows on the adjacent component coloring surface should not have obvious color difference. C. There shall be no aluminum chips, burrs, oil spots or other stains on the surface of doors and windows, and there shall be no overflow adhesive at the assembly connection. 3. size deviation aluminum alloy door and window frame size deviation to the minimum. 4. aluminum alloy door and window components aluminum alloy door and window components should be firmly connected, and corrosion-resistant filling materials are needed to seal and waterproof the connection parts. 5. look at the material in the material material on the main six aspects can be referred to: 1. thickness: aluminum alloy sliding door has 70 series, 90 series two kinds, residential interior aluminum alloy sliding door with 70 series can be. The series number represents the number of millimeters of the structural dimension of the door frame thickness. Aluminum alloy sliding window has 55 series, 60 series, 70 series, 90 series four. Series selection should be based on the size of the window and the local wind pressure value. Aluminum alloy sliding windows used as enclosed balconies should not be less than 70 series. 2. Strength: The tensile strength should reach 157 Newton per square meter and the yield strength should reach 108 Newton per square millimeter. When purchasing, you can bend the profile moderately by hand, and it should be able to recover after you let go. 3. color: the same root aluminum alloy profile color should be consistent, such as color difference is obvious, that is not suitable to buy. 4. Flatness: check the surface of aluminum alloy profile, there should be no depression or bulge. 5. Gloss: aluminum alloy doors and windows to avoid the purchase of open surface bubbles (white spots) and ash (black spots), as well as cracks, burrs, peeling and other obvious defects of the profile. 6. Degree of oxidation: The thickness of the oxide film should reach 10 microns. When purchasing, you can lightly scratch the surface of the profile to see if the oxide film on the surface can be wiped off.

aluminum alloy doors and windows due to light weight, processing and assembly precision, accurate, thus opening and closing light flexible, no noise. However, in actual use, it is not uncommon for aluminum alloy materials to deform doors and windows and push and pull. This requires consumers to buy aluminum alloy doors and windows should be paid attention.
The following six aspects of the purchase guide consumers must keep in mind:
1. logo identification
regular or have a production license manufacturers, in the obvious parts of their aluminum alloy products are marked with product logo, including: manufacturer name or trademark, product name, product model or mark, manufacturing date or number. The packing box shall be marked with the words and signs of "moisture-proof", "handle with care" and "upward. Such as Kemet aluminum profiles do very well in this regard.
2. surface quality
The quality of the surface of doors and windows directly affects the decorative effect of the entire wall after installation. Check the surface quality of doors and windows should pay attention to the following aspects:
A, doors and windows decorative surface should not have obvious damage, it means that the protective film on the surface of doors and windows should not have scratches and scratches.
B. There shall be no obvious color difference on the colored surface of adjacent components on doors and windows.
C. There shall be no aluminum chips, burrs, oil spots or other stains on the surface of doors and windows, and there shall be no overflow adhesive at the assembly connection.
3. size deviation
aluminum alloy door and window frame size deviation to the minimum.
4. aluminum alloy door and window components aluminum alloy door and window components should be firmly connected, and corrosion-resistant filling materials are needed to seal and waterproof the connection parts.
5. look at the material
There are mainly six aspects to refer to:
1. Thickness: There are two kinds of aluminum alloy sliding doors: 70 series and 90 series, and 70 series can be used for aluminum alloy sliding doors inside the residence. The series number represents the number of millimeters of the structural dimension of the door frame thickness. Aluminum alloy sliding window has 55 series, 60 series, 70 series, 90 series four. Series selection should be based on the size of the window and the local wind pressure value. Aluminum alloy sliding windows used as enclosed balconies should not be less than 70 series.
2. 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 bend the profile moderately by hand, and it should be able to recover after you let go.
3. Chroma: The color of the same aluminum alloy profile should be consistent. If the color difference is obvious, it is not suitable for purchase.
4. Flatness: Check the surface of aluminum alloy profile, there should be no depression or bulge.
5. Gloss: aluminum alloy doors and windows avoid purchasing profiles with obvious defects such as open bubbles (white spots) and ash (black spots) on the surface, as well as cracks, burrs, peeling, etc.
6. Degree of oxidation: The thickness of the oxide film should reach 10 microns. When purchasing, you can lightly scratch the surface of the profile to see if the oxide film on the surface can be wiped off.
