Pros and cons of plastic steel profiles

There are two main points in identifying good and bad plastic profiles. First, look at the appearance, the shape of the high-quality profile is uniform, the structure of the inner cavity is reasonable, the color is soft, the protective film is flat, and there is no bubble. The extension of the wall thickness is generally 2 mm. The second is to look at the security code. The genuine plastic steel profile is marked with a security code on the side. It consists of 20 digits of Arabic numerals. The numbers are clear and easy to identify, no duplication, and difficult to wipe off. Inferior steel profiles are digitally blurred, easy to wipe off, and the numbers are repeated.

First of all, look at the packaging of the profile (that is, the protective film attached to the profile is also a trademark). Is it smooth and smooth, with or without bubbles, from one end to the other? The trademarks of counterfeit profiles are hand-pasteed, and there will be a lot of air bubbles, and the skewed, the quality of the trademark is also very poor, you can see it by careful observation. Tear off the protective film to see the surface of the profile. The surface of the profile is very smooth and smooth. There are no bumps and small dots. There is brightness. The color is very white (like milk). Look at the wall thickness of the profile, the main wall thickness of the good profile can be More than two millimeters, and the toughness of the profile, you can use the vise to clamp the wall of the profile, and smash it back and forth. The good profile will not fall easily. (Not applicable in winter, because the temperature in winter is low, the plastic will become very brittle) In terms of the national industry regulations below 10 degrees, it is not allowed to process plastic steel windows. Then there is the anti-counterfeiting code. The real profile will have anti-counterfeiting code. In general, you can distinguish the true and false without calling the phone. There will be 4 to 6 code groups on a 6-meter profile. Look at the writing of the code group is clear and complete, (fake profiles are hand-brushed with a very simple transfer machine after leaving the factory, it will be blurred), the true profile of the code group is unique, and the fake profile (through a batch) the code group is the same (by the relationship of equipment costs), also check the phone to check the code.
