Chicco will tell you what you need to pay attention to when choosing aluminum profiles for doors and windows: First of all, the price fluctuates, and different profiles will lead to different prices for aluminum alloy doors and windows. Although the price of profiles is not different every day, there are still small changes. Window size, surface treatment, profile thickness, glass, accessories, etc. will all affect the price of aluminum alloy doors and windows. In addition, the prices of aluminum alloy door and window profiles of different brands are also very different, and there are also big differences between different origins of the same brand.

Good selection: happy selection: crying. In this important part of purchasing, the following elements must be considered: 1. Look at the thickness of the profile and the flatness of the related notches: the thickness of the good profile should be above 1.0mm, and the groove The mouth is flat. 2. Look at the strength: When purchasing, you can bend the profile moderately with your hands, and it should be able to recover after letting go. 3. Chroma: The color of the same aluminum alloy profile should be the same. If the color difference is obvious, it is not suitable for purchase. 4. Glossiness: avoid the purchase of aluminum alloy doors and windows with open bubbles (white spots) and slag (black spots) on the surface, as well as cracks, burrs, peeling and other obvious defects. 5. Degree of oxidation: the thickness of the oxide film should reach 10 microns. When purchasing, you can scratch the surface of the profile to see if the oxide film on the surface can be wiped off.

Everyone is happy if you choose a good one, and you can cooperate for a long time in the future. If you choose a bad one, the better one is just what others need. The low price transfers. The general warehouse squats to see if there are any useful places in the future. The scraps were sold and a lot of money was spent, so I still have to go to other places to re-import. Therefore, we must choose a good aluminum profile for doors and windows.
