uPVC Profile pros and cons identification


There are two main points in identifying the pros and cons of uPVC Profile. First, look at the appearance. The high-quality profiles have uniform dimensions, reasonable internal cavity structure, soft color, smooth protective film, no bubbles, and the wall thickness of the extension part is generally 2 mm. The second is to look at the anti-counterfeiting code. The authentic plastic steel profile is marked with an anti-counterfeiting code on the side, which is composed of dotted 20-digit Arabic numerals. The numbers are clear and easy to identify, without repetition, and not easy to erase. Inferior plastic steel profile coding numbers are fuzzy, easy to erase, and the numbers are often repeated.


Check whether the packaging of the profile (that is, the protective film on the profile is also a trademark) is flat and smooth, there are no 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 a lot of bubbles, and skewed, the quality of the trademark is also very poor, you can see through careful observation.

Tear off the protective film and look at the surface of the profile. The surface of the good profile is very flat and smooth, there are no uneven spots, there is brightness, and the color is really white (like milk). Look at the wall thickness of the profile, the main wall thickness of the good profile can be It is more than two millimeters, and 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 is lower in winter, and the plastic will become very brittle). According to the relevant national industry regulations, it is not allowed to process plastic steel windows in an environment below 10 degrees Celsius.

Another thing is to look at the anti-counterfeiting code. There will be anti-counterfeiting code on the real profile. Generally speaking, you can distinguish the true from the false without calling the inquiry phone. There will be 4 to 6 coding groups on a 6-meter-long profile* *See if the handwriting of the inkjet code group is clear and complete, (the counterfeit profiles are manually brushed up with a very simple transfer machine after leaving the factory, and they will be blurred), and the inkjet code groups for fake profiles (through one batch) It's the same (subject to equipment cost), also check the coding by calling the inquiry phone.
