Like other building materials, UPVC Profile has high quality and low quality. How to distinguish the quality of UPVC Profile? Let's see what methods are available below:
1. Look at the appearance of UPVC Profile:
The high-quality UPVC Profile has uniform dimensions, reasonable internal cavity structure, soft color, smooth protective film, no bubbles, and the wall thickness of the extended part is generally 2 mm.
First look at whether the UPVC Profile packaging (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, a closer inspection can tell.
Tear off the protective film and look at the surface of the UPVC Profile. The surface of the good profile is very flat and smooth, there are no uneven spots, there is brightness, and the color is very white (like milk). Look at the wall thickness of the profile, the main wall thickness of the good profile It can reach more than two millimeters, and there is 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. ) Strictly speaking, it is not allowed to process plastic steel windows in an environment below 10 degrees according to the relevant national industry regulations.
2. Look at the anti-counterfeiting code of UPVC Profile:
An anti-counterfeiting code is printed on the side of the genuine UPVC Profile, 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 blurred, easy to erase, and the numbers are often repeated.
There will be anti-counterfeiting coding on the real UPVC Profile. Normally, you can distinguish between true and false without calling the query. There will be 4 to 6 coding groups on a 6-meter-long profile. First of all, check whether the handwriting of the coding group is Clear and complete, (counterfeit UPVC Profiles are manually brushed up with a very simple transfer machine after leaving the factory, and will be blurred). The inkjet set of the real UPVC Profile is unique, and the fake profile (one batch is accepted) The coding group is the same (subject to the equipment cost), also check the coding by calling the inquiry phone.
