What should we know in the first step of purchasing thermal-break aluminum doors and windows?
Nowadays, when we renovate our houses, we basically replace the old doors and windows with mainstream energy-saving, heat-insulating, sound-insulating, and sealed thermal-break aluminum doors and windows. But what should we know in the first step of purchasing thermal-break aluminum doors and windows? It is not the so-called price, nor the brand of doors and windows, but aluminum.
When we buy in many building materials markets, we often see doors and windows named after aluminum brands and some doors and windows brands with self-created names. Especially in those self-created brands, the first thing we ask is what brand of thermal-break aluminum profiles are used in your thermal-break aluminum doors and windows? Where are they produced?
Why is it important to consult the aluminum brand in the first step of purchasing thermal-break aluminum doors and windows?
Because the prices of different products and brands of thermally broken aluminum profiles vary greatly, and the quality is also uneven, the first step is to understand the aluminum brand, and then discuss the series models and prices. At present, the main domestic thermally broken aluminum profile products are in Guangdong, Jiangxi, Shandong, and Hebei; the thermally broken aluminum profiles in these places occupy more than 80% of the domestic market share, among which the thermally broken aluminum profiles in Guangdong have the best quality and are slightly more expensive. Guangdong occupies seven places among the top ten domestic aluminum companies. So the workmanship quality of aluminum from different origins is different.
At present, the well-known Guangdong thermally broken aluminum profiles on the market range from 21,000 to 29,000 yuan per ton, depending on the aluminum brand, while the thermally broken aluminum profiles in Jiangxi, Shandong, and Hebei range from 16,000 to 21,000 yuan per ton (the above prices are the ex-factory prices of most manufacturers, excluding a few well-known local manufacturers). The price of aluminum determines the difference in the quality of thermal insulation aluminum materials. Branded thermal insulation aluminum profiles are basically more than 20,000 yuan per ton. This type of thermal insulation aluminum profile uses 6063T5 material. The aluminum surface is smooth and flat, well oxidized, and not easy to lose paint. However, the thermal insulation aluminum profiles produced by some small factories have many impurities, the material hardness is relatively soft, the compressive performance is poor, pits on the surface, the paint film is thin and the thickness is not enough. The most important thing is to worry about its quality. Some manufacturers have an aluminum thickness that meets the national standard. The aluminum strength is not enough, so the doors and windows made of such aluminum will not last long.
Therefore, the first step in purchasing thermal insulation aluminum doors and windows is to consult the merchant clearly about which brand of aluminum they are purchasing. It is particularly noted here that the larger the brand of aluminum, the more transparent the price, the lower the merchant's profit, and the higher the profit of doors and windows that do not mention the aluminum brand. Let me tell you about my personal experience. My wife used to work in a pharmacy and knew what medicine to buy for children. When I took the brand medicine my wife mentioned to the pharmacy, I asked several brands and they all said they didn't have any. The pharmacist recommended some medicines I had never heard of. Although they have the same effect, their profits are much different for the pharmacy. This is the same as when we make doors and windows. The more big brands of aluminum materials, the more transparent the price, the lower the profit. The more unheard-of brands, which don't know the price, and you can't find a place to compare. Often, this type of doors and windows has higher profits.
In addition to understanding the aluminum brand, we also need to understand whether the insulation strip is made of PA66 nylon strips, whether the hardware configuration is domestic or imported hardware, whether the glass is ordinary or tempered, etc. Only when you know everything, you will not be deceived by the merchants.
