How can a storm hit a new door and window so vulnerable?

Since the summer of this year, bad weather such as storms and typhoons have occurred in many places in China. Recently, the stormy mode has also been opened in the north of China. Heavy rainfall has caused flooding in places such as Shanxi and Hebei, and the grievances are serious. The raging storms, in addition to causing inconvenience to people's lives, also lead to safety accidents caused by damage to doors and windows: such as falling windows, broken glass, and even bruising pedestrians and vehicles.

The safety hazards of doors and windows brought about by the storm have caused the attention of many residents. Mr. Zhang, who lives in Hebei, said: "There are several households whose doors and windows have been scraped off in our community. Some of them have been used for more than ten years. It has been used for so long, the door and window materials and accessories are aging, and it is impossible to survive the storm. Normal. But the doors and windows of my house were changed only in the first two months. I was also scratched in this storm. How could the new doors and windows be so vulnerable?"

In this regard, some people have analyzed the reasons:

1. Hardware accessories are inferior

Whether the hardware accessories are good or bad is the key to whether the doors and windows are durable. Some of the top ten doors and windows brands will use high quality imported hardware accessories to ensure quality. However, some door and window manufacturers use inferior and cheap hardware accessories in order to save costs. This inferior hardware is prone to deformation, bending, tilting, rusting, etc., and it is easy to cause swaying, water seepage, and air leakage.

2. The quality of aluminum is not good

The quality of aluminum alloy doors and windows and aluminum materials affects the robustness, pressure resistance and service life of doors and windows. Therefore, the state has regulations on the thickness and hardness of aluminum. For example, the national standard aluminum alloy door and window profiles have a thickness of 1.4mm, but some of the doors and windows brands that are not well-tested, the aluminum doors and windows used are lower than the national standards. When the storm raged and slammed into the doors and windows, the poor quality aluminum was easily deformed, causing the glass to break.

3. The glass is not up to standard

The state stipulates that the windows outside the 7th and 7th floors must be made of safety glass, that is, tempered glass. Because the tempered glass is strong in resistance to wind pressure and is not easily broken, in the face of severe storm impact, the compressive performance of tempered glass far exceeds that of ordinary glass, and the risk of glass breakage is greatly reduced. In addition, even if the tempered glass falls to the ground, it will not splash glass fragments and hurt the passers-by. However, most of the safety glass of the door and window brand has not met the relevant national standards.
