Windbreak and dust suppression net is processed into a certain geometric shape, opening rate, and combination of different hole shapes based on wind tunnel test results of the actual implementation site environment, utilizing the principles of aerodynamics. This creates an airflow interference pattern inside the wall when the flowing air (strong wind) passes through from the outside, achieving the effect of strong wind outside, weak wind inside, small wind outside, and no wind inside, thereby preventing dust from being blown around.
