Ly profiles tell you how to choose good profiles

To choose a good plastic steel door and window, we must first understand the PVC profile used for plastic steel door and window.

First of all, we should understand the PVC profile selected for plastic steel windows. PVC profile is the decisive factor for the quality and grade of plastic steel windows. A good PVC profile should be a multi cavity designed by the example, with wall thickness. The formula contains anti-aging and anti ultraviolet additives. From the appearance, it should have a smooth surface and blue and white color. The medium and low-grade profiles are white and yellowish. The sunscreen ability of this color is off. After a few years of use, it will become more and more yellow until aging, deformation and embrittlement. The reason is that there is too much calcium in the profile formula. Considering that the window area of most houses is large (such as sealed balcony) and there are many high-rise buildings, the wall thickness of the profile should be greater than 2.5mm, and the inner cavity is a profile with three cavity structure (with closed drainage cavity, isolation cavity and reinforcement cavity), so as to ensure that the window will not deform for decades. In addition, such profiles are not easy to change color and aging.
