The light steel roof louver vent is installed along the slope and horizontally perpendicular to the roof ridge, that is, parallel to the mountain wall of the factory building, usually parallel to the roof. It is characterized by flexible layout and easy waterproof treatment. According to the structure, roof smoke vent can be divided into roof louver vent, large throat steel welded skeleton smoke ventilator and small integrally suppressed skeleton smoke ventilator. What needs to be pointed out here is that the upper end of the slope smoke ventilator with a large throat is prone to water accumulation in rainy days. If the diversion measures are not properly handled, leakage will occur. Therefore, generally the slope smoke ventilator with a throat greater than 2000mm should be used layout across the roof ridge, so that the roof louver vent has better water resistance.

The main performance of the roof louver vent is to meet the ventilation needs of the plant. The selection and installation of the light steel roof smoke vent should follow the principle of density and reasonable layout, which not only meets the requirements of use, but also avoids excessive investment and waste. For workshops with low air change requirements and a small area for installation of air towers, the arrangement method of installing lighting belts between the air towers along the slope can be adopted, which combines natural ventilation and daylighting, and is relatively balanced. It is currently more commonly used. Installation form of slope smoke ventilator.
