There are two main points in identifying the pros and cons of UPVC Profiles. First, look at the appearance. The high-quality profiles have uniform dimensions, reasonable internal cavity structure, soft color, smooth protective film, no air bubbles, and wall thickness of 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.
First look at whether the packaging of UPVC Profiles (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, it has brightness, and the color is really white (like milk). Looking at the wall thickness of the profile, the main wall thickness of the good profile can reach 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 easily (not in winter. Applicable, because the temperature in winter is relatively low, the plastic will become very brittle) Strictly speaking, the processing of plastic steel windows is not allowed in the environment below 10 degrees according to the relevant regulations of the industry.
Another thing is to look at the anti-counterfeiting code of UPVC Profiles. There will be anti-counterfeiting code on the real profile. Generally, you can distinguish the true from the false without calling the inquiry phone. There will be 4 to 6 sprays on a 6-meter-long profile. First of all, check whether 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). The inkjet code groups for real profiles are the only ones. The coding groups of fake profiles are all the same (subject to equipment costs).
