The quality of plastic steel doors and windows depends on its UPVC profile

uPVC Profile


UPVC profile is the decisive factor for the quality and grade of plastic steel doors and windows. A good UPVC profile should be a reasonably designed multi-cavity, with a wall thickness, and the formula contains anti-aging and anti-ultraviolet additives. From the appearance, it should have a smooth surface and a blue and white color. In the process of purchasing plastic steel doors and windows, we can ask the manufacturer for different profile sections and compare them together.


The quality of plastic steel doors and windows depends on its hardware

The hardware of high-end doors and windows are all made of metal, and their inherent strength, appearance, and usability directly affect the performance of doors and windows. Nowadays, many low- and medium-grade plastic steel parts on the market use plastic hardware, so their service life is very hidden. Therefore, in the process of purchasing plastic-steel doors and windows, we need to pay more attention to whether the hardware of plastic-steel doors and windows is made of real metal or plastic hardware.


The quality of plastic steel doors and windows depends on its assembly quality

The quality of plastic steel doors and windows will also be affected by its assembly quality. If it is assembled well, it is naturally durable, and if it is not assembled well, the best materials will be wasted. When we buy plastic steel doors and windows, we need to pay attention to whether the welding angles are neat, whether the hardware is complete, and whether the appearance of the doors and windows is smooth and clean.
