Aluminum alloy doors and windows mainly refer to doors and windows with aluminum alloy as the stress frame, and aluminum alloy is a building material made of aluminum as the main material and some alloy elements that enhance hardness and strength. Aluminum alloy doors and windows on the market can be divided into three grades according to the price. Low grade products are 200 yuan ~ 400 yuan/square; Medium grade products are 500 yuan ~ 1000 yuan/square; high-end products range from 1200 yuan to 5000 yuan per square meter. What factors affect the price difference of aluminum alloy doors and windows? Let's introduce it through three aspects.
1. Aluminum alloy material
Different aluminum alloy materials have a very important influence on the price of aluminum alloy doors and windows. There are two influencing elements here. One is the thickness of aluminum alloy. This is very easy to understand. Different series of aluminum alloy have different thickness, the thicker the aluminum alloy material, the higher the price and the longer the service life. For example, the price difference between 50 series and 70 series products of the same brand is about 400 yuan.
Another element is that the treatment of aluminum surface is different, with paint treatment about 60 yuan/square; Fluorocarbon spraying about 450 yuan/square; Wood grain treatment about 550 yuan/square meter; powder spraying is about 200 yuan/square meter. Surface treatment is still very important for doors and windows. Doors and windows with better surface treatment will not change color or fade for many years. Now some doors and windows will also add Bridge-cutoff aluminum alloy design to increase the thermal insulation of materials, and the price will increase by 300~500 yuan.
2. Hardware accessories
Although hardware accessories are relatively small parts, they are also important factors that affect the price of aluminum alloy doors and windows. The prices of some common hardware accessories on the market are between 100 yuan and 200 yuan; Those with better brands are between 200 yuan and 300 yuan; the price of hardware accessories of famous foreign brands is between 300 yuan and 400 yuan; The price of hardware accessories with special craftsmanship is between 500 yuan and 600 yuan. Although the price difference is not very large, the doors and windows needed at home are not one or two, and it is a big expense if they are accumulated together.
3. Brand
Brand should be the best factor to understand. Different brands have different product quality and prices. Many people do not know the specific ingredients when purchasing aluminum alloy doors and windows. They directly judge the quality of products through brands. Products of big brands are more in line with national production standards, it is more assured to use, of course, the price is higher.
4. Manufacturing process
The reason why aluminum alloy doors and windows are liked by people is inseparable from their advantages such as sound insulation, aging resistance, tightness and wind pressure resistance. However, these advantages can only be achieved by strict manufacturing techniques, the superb manufacturing process has made more high quality products, thus affecting the price of the products.
After reading the above introduction about the price of aluminum alloy doors and windows, do you have a clearer understanding of aluminum alloy doors and windows. Doors and windows are products that will be used in home decoration. Replacing doors and windows is a particularly tedious thing, so choosing a good door and window is still very important. I hope today's introduction about the price of aluminum alloy doors and windows can provide some help when you choose doors and windows.
From another perspective
Now home decoration, most consumers choose aluminum alloy doors and windows, one is good performance, the other is strong and durable.
I believe that many owners have seen many brands when buying, and the price ranges from 200 yuan to 2000 yuan, or even higher. Some people know the tricks, but some people are very confused, why do products with similar appearance have so many differences and have a feeling of being cheated, so I chose low-priced products. After two or three years of use, all kinds of quality problems have come out, air leakage, rain leakage, deformation and so on.
Why is the price difference of aluminum alloy doors and windows so big? Of course, it has something to do with its materials and workmanship. Today, I will take you to compare the aluminum alloy doors and windows of different brands.
1. Different angles
Angle codes are used to connect the corner joints of aluminum alloy doors and windows in order to be firm, non-deformed or water-free. Currently, there are four common angle codes:
Figure 1 shows the activity angle code: the activity angle code is connected to aluminum through spring buckle to fix doors and windows by tightening them through screws. The connection is not tight enough, and the spring part is easy to rust and lose elasticity after a long time of water intake, or fracture.
Figure 2 shows the angle type aluminium alloy door angle code: this is to insert the angle code into the profile type, apply glue on the section of the profile, and press it through the machine to form it in one piece, which is seamless and not easy to crack.
Figure 3 shows the special angle code for glue injection-extrusion aluminum corner brace: this is to insert the angle code into the profile, press and form it by machine, then inject the imported two-component glue, and use special tools to fix it until the component glue dries out. Effectively prevent corner of the window leakage of rainwater, and at the same time increase the strength of the corner
Figure 4 is cast aluminum angle code: cast aluminum angle code is mostly used for system doors and windows. It is also used to insert the angle code into the profile, and then inject the imported two-component glue into the machine to fix it with special tools, until the component glue dries out. Improved corner strength and maximum waterproof
The above four angle codes, four processes and four prices, among which the cost of movable angle codes is the lowest and the cost of cast aluminum angle codes is the highest.
II. Different structures
Figure 5 shows the three-Cavity Structure. This structure is the simplest, that is, the aluminum material is separated from the middle by heat insulation strips, so as to achieve the effect of heat insulation anacoustic.
Figure 6 is the multi-cavity structure sound insulation and flow blocking cotton multi-point contact foam isobaric adhesive tape seal to ensure the effective lap amount and ensure the energy saving, sound insulation and anti-condensation effect of the whole window.
3. Different hardware
The price of hardware also ranges from 100-1000 yuan, or even higher. Foreign hardware is better than domestic ones. At present, it represents German Noto, American himec, German house, Italian GIS and so on. The quality of door and window switches and the service life of doors and windows often depend on the service life of door and window hardware quality, so broken bridge aluminum doors and windows hardware accessories must not be greedy for cheap.
IV. Different raw materials
Different raw materials are the main factors leading to the price of aluminum alloy doors and windows, such as replacing primary aluminum with recycled aluminum, replacing PA66 nylon insulation strip with PVC insulation strip, replacing EPDM and TPE sealing strip with PVC sealing strip, etc, these are just a part of them. Basically, every basic material of the window is fishy, and it is difficult for laymen to distinguish.
V. Different drainage systems
Figure 7 is a drainage hole directly punched on the window frame, which can play the role of drainage, but when it comes to the wind in rainy days, it is easy to cause rainwater to pour back, thus indoor water.
Figure 8 shows the hidden drainage system, which can effectively prevent rainwater from pouring back in windy and heavy rain.
The above five points are only part of the price of aluminum alloy doors and windows, and many other factors, such as glass, color, craft, etc., are all factors leading to price differences. Therefore, it looks similar, but in fact it is much worse, always remember the truth that good goods are not cheap, and there is no good goods at a low price.
