Modern industrial plants are mostly constructed of steel structures. In order to solve the disadvantages of lighting, ventilation, and fire-fighting and smoke exhaust of steel structure plants, most business owners usually install industrial smoke ventilator on the roof to achieve natural lighting and ventilation inside the plant. The waterproof performance of smoke vent skylights is one of the important factors considered by business owners, so how can smoke ventilator effectively achieve waterproofing?

Industrial smoke ventilator is installed on the roof of an industrial plant in a horizontal or vertical arrangement, with a slope range of 10°-60°. When the roof angle exceeds 10°, it is called a "sloping roof". According to relevant regulations, when the slope of the plant reaches 30°, the force on the slope can be reduced, which is conducive to roof drainage. Generally, the drainage of the steel structure factory roof is mainly made of aluminum alloy drainage panels, and the surface of the natural ventilators will also be waterproofed to ensure its drainage performance.

Under normal circumstances, in order to ensure the smooth drainage of the smoke vent skylights, a unique drainage groove or drainage pipe design is used inside the roof ventilator. This design will guide rainwater from the top of the smoke vent rooflight to the factory building surface, thereby preventing rainwater from passing through The roof natural ventilators penetrate into the interior of the plant.

The flashing plate set on the outer protective plate of the finished ventilator has good sealing effect and good waterproof performance, which can achieve the effect of roof waterproofing. The roof ventilator is made by the full-structure waterproof technology, and then the anti-corrosion treatment is carried out on the galvanized technology, which can enhance the waterproof performance of the ventilator.
