Windbreak and dust suppression mesh utilizes aerodynamic principles, processed into specific geometric shapes, opening rates, and combinations of different hole shapes based on wind tunnel test results in the implementation site environment. It creates an upper and lower interference airflow within the wall when the flowing air (strong wind) passes through, achieving the effect of strong wind on the outside, weak wind on the inside, slight wind on the outside, and no wind on the inside, thereby preventing dust from flying.
