Many large-scale factories use metal building ridge vents to achieve the purpose of fresh air inside the building, brightening natural lighting in the space, and removing indoor dirty air. Clients also usually call ridge ventilator and natural roof ventilation.

Large-scale metal building ridge vents use the difference between indoor and outdoor air temperature and wind pressure to meet the requirements of indoor air flow. Ridge ventilator uses FRP daylighting panels as daylighting materials on a large area to increase the natural daylight of the plant without electricity and easy maintenance. The large-scale factory building has both ventilation and lighting skylights, which saves business costs and is widely welcomed by customers. Large-scale plant roof smoke vent, as energy-saving and environmentally-friendly ventilation equipment, has become indispensable infrastructure facilities for steel-structure industrial workshops and factories.
