Natural ventilator has been widely used on steel structure roofs industrial plants. Waterproof performance is the basic requirement for natural vent. Mcwell's full-structure waterproof technology ensure roof vents rainproof and snowproof performance,and there are other advantages, such as good structural safety, long service life, and low product maintenance rate. 

Wind resistance: The aerodynamic coefficient is the ratio of the pressure (or suction) formed by the wind on the surface of the engineering structure and the theoretical wind pressure calculated according to the incoming wind speed. In aerodynamics, this coefficient reflects the distribution of stable wind pressure on the engineering structure and the surface of the building, and varies with the shape, size, enclosure and shielding conditions, and airflow direction of the building. 

Structural safety: We know that the load resistance of ridge ventilator depends on factors such as the design form of the steel frame, the material specifications of the steel frame, the thickness of the outer guard and the rain shield. The design of Mcwell's smoke vents are designed by structural engineers based on the wind load, snow load, seismic intensity and other related factors of the project site to use professional software to simulate and calculate.
