Is the price of aluminum alloy doors and windows affected by aluminum market? Why are the prices so different? Different profiles will lead to the price difference of aluminum alloy doors and windows. At present, the price of ordinary aluminum is about 19800 / ton. Due to the surface treatment (oxidation, electrophoresis and electrostatic powder spray), the price of thermal insulation aluminum will be slightly higher, about 26000 / ton. Moreover, because of the fluctuation of aluminum market, these prices are not fixed.
Aluminum alloy profile is a kind of non-ferrous metal structure material. It is widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, construction, decoration and so on. This paper mainly introduces the application in aluminum alloy doors and windows, because it has small density and low melting point, which also means that it is easy to process and has corrosion resistance. Due to the low strength and hardness of pure aluminum, the strength of aluminum alloy profile will be very high by surface treatment technology and adding alloy elements. Now more and more decoration uses aluminum alloy as the door and window frame, and occupies an important position.
Aluminum alloy door and window profile specifications are: 35 series, 38 series, 40 series, 60 series, 70 series, 80 series, 90 series, etc. The so-called 35, 38 80 series and 90 series refer to the width of aluminum alloy profile main frame, which are 35mm and 38mm respectively 80 mm, 90 mm. Sealing balcony usually uses 70 series or 90 series, if less than 70, the firmness is difficult to guarantee.
In other words, according to the different processing methods of electrostatic spraying and carbon coating, it can be divided into several kinds. At present, 85% of the consumption in the market is electrostatic powder spraying profiles, namely color aluminum profiles.
The aluminum alloy profiles produced by different enterprises are basically the same, but there are some differences in the specific structure. However, it should be noted that the thickness of aluminum materials used in different occasions is also very particular. The general flat doors and windows should meet the requirements of more than 50 series, the sliding doors and windows should generally meet the requirements of more than 60 series, and the specification of aluminum alloy profiles for curtain wall is 110 series-185 series.
The price of aluminum alloy profiles is mainly calculated according to tons. This market fluctuates greatly, so there are differences in prices at different times, sometimes quite large differences. The price of aluminum alloy door and window profiles is mainly based on the number of meters per square meter. According to the different types of materials, processing technology, materials, thickness, impurities and other factors, the price difference is relatively large, generally ranging from more than 100 to thousands.
Why is the price of aluminum alloy doors and windows affected by the aluminum market? If the price of profile increases greatly, beyond the tolerance of aluminum alloy door and window manufacturers, the price of door and window products will rise. Even if the same kind of aluminum profile is used and the brand is different, the price of aluminum alloy doors and windows is not uniform. Because although aluminum profile is the same, but the added value of different brands is different, the production process is also different, the price will not be the same naturally. For example, liefan's aluminum alloy doors and windows are made of high-grade heat-insulating aluminum materials with higher quality, so they usually cost thousands of yuan per square meter. Other popular brands use ordinary thermal insulation aluminum, which costs only 380-950 yuan per square.
