Windproof and dust suppression net is processed into a certain geometric shape, aperture rate, and different hole shape combinations based on wind tunnel test results from the implementation site environment, utilizing the principles of aerodynamics. It creates an airflow interference pattern inside the wall, allowing the passing air (strong wind) to form an upper and lower interference when passing through the wall, achieving the effect of strong wind on the outside, weak wind on the inside, small wind on the outside, and no wind on the inside, thereby preventing dust from flying.
