How to choose plastic steel doors and Windows

Plastic steel doors and Windows with its excellent performance and beautiful appearance has gradually become a new favorite decoration. However, plastic steel doors and Windows in China, after all, still belong to a new type of building materials, most people are still relatively unfamiliar with it. So, how to distinguish the advantages and disadvantages of plastic steel doors and Windows?

First of all, it must be clear that plastic steel doors and Windows, like other building materials, have high, medium, low grade and quality and inferior points, can not be confused. The quality and grade of plastic steel doors and Windows are mainly divided into the following steps:

The first step is to understand the UPVC profiles selected for plastic steel doors and Windows. UPVC profile is the decisive factor of the quality and grade of plastic steel doors and Windows, a good UPVC profile should be a reasonable design of multi-cavity, wall thickness, the formula contains anti-aging, anti-ultraviolet additives, from the appearance of the surface should be smooth, the color green and white.

In particular, we should remind you that many people think that the plastic steel Windows are the same white, in fact, the high-end UPVC profile color should be white and green, such color anti-aging performance is good, in the outdoor wind and sun for thirty or fifty years, there will be no aging, discoloration, deformation. The middle and low profile is white yellow, this color has poor sunscreen ability, and will become more and more yellow after a few years until aging, deformation, brittle, the reason is that the formula of the profile contains too much calcium. You can see this from the calcium plastic Windows that were widely used a few years ago but have now changed beyond recognition. Therefore, we must carefully choose the UPVC profile, and we can ask the manufacturer for different profile sections to be compared together, which is better and which is worse can be clearly seen.

The second step is to look at the hardware selected for doors and Windows. The hardware of high-grade doors and Windows are made of metal, and its internal strength, appearance and usability directly affect the performance of doors and Windows. Many low - and medium-grade plastic steels are made of plastic hardware, and there are great hidden dangers in their quality and life.

The third step is to see the assembly quality of doors and Windows, mainly to see whether the appearance is smooth and non-destructive, whether the welding Angle is cleaned up, whether the hardware is matched, whether there is steel lining and so on.

The most important point is that we must check whether the door and window manufacturers have the production license issued by the construction committee, do not be greedy for cheap, the use of plastic steel Windows produced by street workshops, its quality and reputation can not be guaranteed.
