Besides the appearance design and practical performance of modern industrial plants, users have higher requirements for the internal environment. Steel structure roof smoke vent is a common natural ventilation and lighting facility in modern industrial plants. It has played an important role in improving the internal environment of the plant and assisting the production and operation of the enterprise.

Steel structure smoke ventilation is characterized by taking into account ventilation and lighting, energy saving and environmental protection, and easy to maintain. Good quality steel structure natural vent is installed on the roof of the factory. The main materials are different specifications of section steel, color steel plates and daylighting panels. For workshops with special production environments, such as those with anti-rust and anti-corrosion requirements, color aluminum plates, stainless steel profiles, etc. can be used.

The main components of roof vents are: main and secondary frames, rain-proof panels, water collection troughs, falling water systems, outer guard plates, flooding plates, ends, valve plates and electronic control systems. The design and installation should follow the principle "reasonable layout, type selection and application" and pursues the balance of performance and investment, and fully play the role of daylighting natural ventilator. There are several main performances for the selection of natural roof ventilation: ventilation performance, structural safety, service life, rain and snow resistance, etc. Users should focus on the advantages and disadvantages of the products from these aspects when selecting plant ventilation skylights.
