How to Identify the Quality of UPVC Profiles

First, look at the appearance. High-quality profiles have uniform dimensions, reasonable inner cavity structure, soft color, smooth protective film, no bubbles, and the extended wall thickness is generally 2 mm.

Second, check whether the packaging of the profile (that is, the protective film on the profile is also the trademark) is flat and smooth, whether there are 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, so there will be many bubbles, and they are crooked. The quality of the trademark is also very poor, which can be seen by careful observation.

Third, tear off the protective film to look at the surface of the profile. The surface of a good profile is very flat and smooth, without small bumps, with brightness, and the color is very real and white (like milk). Then look at the wall thickness of the profile.

The main wall thickness of a good profile can reach more than two millimeters. In addition, the toughness of the profile can be clamped with a vise to clamp the wall of the profile and bend it back and forth. A good profile will not fall off easily.
