Windproof and dust suppression net is processed into a certain geometric shape, opening rate, and different hole shape combinations based on wind tunnel test results in the implementation site environment, utilizing aerodynamic principles. It creates an air flow interference pattern inside the wall when the flowing air (strong wind) passes 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.
