A few days ago, a customer asked me, "Why are the prices of aluminum alloy doors and windows on the market so different? Cheap, as cheap as more than 100 yuan per square meter, and expensive as expensive as several thousand yuan per square meter." The reason is actually very simple, the quality Alright. However, how to judge the quality of aluminum alloy doors and windows is also a technical task, otherwise you will spend high prices to buy cheap goods.

Today, Baydee uPVC Profile will share with you the methods to distinguish the quality of aluminum alloy doors and windows from three aspects.

First, look at the sign

When purchasing aluminum alloy doors and windows, you must pay attention to whether there are detailed product marks on the doors and windows. On the one hand, you can see if there are "product name", "product model", "manufacturer name", "production date", "production number" and other information on the doors and windows. On the other hand, you should also check whether there are words and marks such as "moisture-proof", "handle with care" and "upward" on the packaging box.

In addition, everyone must ask the other party to show the production license and other documents. As long as it is a regular company, these things are basic operations.

Second, look at the surface

The workmanship of the surface of aluminum alloy doors and windows directly affects the decorative effect after installation. If the quality of the surface of the doors and windows is not good, then installing it in your home will make you feel irritable and seriously affect your happiness.

You can check the workmanship of the surface from these aspects: 1. Whether there are obvious scratches or bumps on the surface of doors and windows; 2. Whether the components on the doors and windows have obvious color difference; 3. Whether there are aluminum chips, burrs, dirt on the surface of doors and windows 4. Whether the connection parts of the door and window components are flat and the angle is regular; 5. Whether the sealing strip is even and smooth, with or without leaks, etc.; 6. Whether the glass has scratches, cracks, bubbles, etc.

Third, look at the size

Under normal circumstances, the manufacturer will have construction drawings, you can ask the manufacturer to show it, and then compare the actual size of the aluminum alloy doors and windows to see if there is any deviation. Of course, the smaller the deviation of aluminum alloy doors and windows, the better. If the difference is large, it may not be so harmonious if you install it in your home.
