UPVC Profile is more and more widely used in enterprises, and some UPVC Profiles are confusing. How to identify the pros and cons of UPVC Profile, let's talk about this information.
There are two main points to identify good and bad UPVC Profiles. First look at the appearance, the high-quality profiles are uniform in shape and size, the inner cavity structure is reasonable, the color is soft, the protective film is flat, no bubbles, and the wall thickness is generally 2 mm. The second is to look at the anti-counterfeiting code. The side of the authentic UPVC Profile is marked with an anti-counterfeiting code, which is composed of 20-digit Arabic numerals in the form of dots. The numbers are clear and easy to identify, without repetition, and are not easy to erase. Inferior UPVC Profile coding numbers are blurry, easy to erase, and the numbers are often repeated.
First look at the packaging of UPVC Profile (that is, the protective film on the profile is also a trademark) whether it is smooth and smooth, with or without air bubbles, and whether it is in a straight line from one end to the other. The trademarks of counterfeit profiles are all pasted by hand, there will be many bubbles, and they are crooked, and the quality of the trademarks is also very poor, which can be seen by careful observation. Tear off the protective film to see the surface of the profile, the surface of the good profile is very smooth and smooth, there are no uneven spots, there is brightness, and the color is very white (like milk). Looking at the wall thickness of the profile, the main wall thickness of a good profile can reach more than two millimeters. There is also the toughness of the profile. You can clamp the wall of the profile with a vise and break it back and forth. The good profile will not fall off easily (not applicable in winter, because the temperature in winter is relatively low, the plastic will become very brittle). Strictly speaking, it is not allowed to process plastic steel windows in an environment below 10 degrees according to the relevant national industry regulations. Then there is the anti-counterfeiting code. There will be anti-counterfeiting code on the real profile. In general, you can tell the authenticity without making an inquiry call. There will be 4 to 6 code groups on a 6-meter-long profile. Check whether the handwriting of the coding group is clear and complete. (The fake profiles are all brushed by hand with a very simple transfer machine after leaving the factory, which will be blurred.) The coding group of the real UPVC Profile is unique, while the fake UPVC profile Profile's (through a batch) coding group is the same (subject to equipment costs), call the inquiry to check the coding.
