storm resistance performance

Today, I want to give you a window storm resistance test. We will check its storm resistance performance through the wind speed, wind pressure, wind level and water flow. Now the highest simulated wind speed has reached 32 meters per second, wind pressure of 822 Pa, flow of 3500 liters per hour, equivalent to an outdoor storm of 12 categories. You can see that the window frame is steady and no water leakage. The window has a good wind resistance and watertightness.
