New house decoration inquiry | How to distinguish the quality and choose aluminum alloy doors and windows
How should we identify and choose good aluminum alloy doors and windows when decorating a new house? At present, there are many types and brands of aluminum alloy doors and windows on the market, especially in the past five years, there are countless branded doors and windows in any region; Due to the large number of brands, there is uneven quality; Because most homeowners and clients do not understand home decoration, it leads to confusion and uncertainty on how to identify and choose high-quality door and window brands.
In recent years, broken bridge aluminum alloy doors and windows have been particularly popular among homeowners and customers. However, due to the pandemic and other reasons, aluminum ingots have skyrocketed in the past two years, and prices have also been affected by many other factors; For example, the purity of aluminum ingots, material thickness and width, overall design, glass thickness, hollow size, whether they are laminated, hardware accessories and other raw materials are all affected. So, how can we as consumers identify and choose good aluminum alloy door and window brands? Now, Lidu Doors and Windows Xiaozhou will share and exchange ideas with everyone.
Nowadays, aluminum ingots have seen a crazy increase in raw materials for doors and windows, and some door and window brand manufacturers have started to sell inferior products at low prices. Can we imagine if such products can pass the inspection? Then consumers buy at a low price, thinking they have found a big bargain; Some low prices may not be visible in appearance; But the actual materials are far apart, such as using cheap accessories, low aluminum purity, and poor hardware accessories to lower prices and attract users; So when choosing aluminum alloy doors and windows, it is important to pay attention to the following points to prevent being deceived and fooled.
1、 Thickness of door and window profiles
In recent years, the commonly used aluminum profiles are the 7, 90, and 100 series, with a national standard wall thickness of 1.2mm or more, and high-quality aluminum profiles with a wall thickness of 1.2mm to 2.0mm.
2、 Use of insulation tape material
Some door and window manufacturers use PVC material instead of the more expensive PA66 material in order to save costs. There is a significant difference between these two materials, and the cost price also varies greatly. PVC material costs several thousand yuan per ton, while PA66 material costs over 20000 yuan per ton.
Identification method: Use a lighter test, if it can ignite, it is PVC.
3、 Degree of oxidation of profiles
How to distinguish the degree of oxidation of profiles? When we purchase, gently scratch the surface of the profile and see if the oxide film on the surface can be wiped off.
Kind reminder: Do not operate on samples from other stores. You can test them on the merchant's display materials.
4、 Visually inspect the surface color of the profile
In most cases, the interface color of high-quality aluminum profiles is silver white and the color is uniform; If there is a significant color difference on the same profile, it indicates poor quality of the aluminum profile and is not recommended for purchase; This is likely to be made by using scrap aluminum and recycling aluminum for casting and forging; You can imagine the quality.
5、 Surface flatness of aluminum profiles
High quality aluminum profiles have a smooth and even surface, without any dents or bulges; The surface of aluminum alloy doors and windows extruded by general manufacturers is flat and shiny; Then some aluminum alloy doors and windows produced by small processing factories may have more or less unevenness and slight bumps on the surface due to machine, raw material, and process problems; The durability of such aluminum profiles is not good, and the product's lifespan is extremely short. So everyone understands that there must be a significant difference in the quality of products with high prices and low prices.
