Natural ventilation system is generally used in steel structure industrial buildings. Ridge ventilator is one of the basic equipment for factory ventilation, which can play a good role in ventilation. As a natural ventilation system, the roof ridge vent takes the temperature difference and heat difference between indoor and outdoor as the power, draws fresh air from the low place, and then evacuates it through the top of the ridge ventilator to dissipate the dirty air in the room. The ventilation building of the entire plant is parallel to the roof, reducing wind pressure and typhoon invasion.

The natural roof ventilation is composed of a main frame and a secondary frame, which is convenient for transportation and installation.

The main frame and secondary frame steel structure of the building ventilation building is convenient to manufacture, and the existing plant can be constructed immediately.

The ventilated building has both daylighting and ventilation integrated, which has low cost and good effect.

The ventilated building has a built-in gutter, which is beautiful in appearance and excellent in integrity.
