Natural ventilation system is installed on building roofs or steel structure workshops to help ventilate the air of inside workshop and improve air quality. Natural ventilation system is mostly suitable for steel structure industrial buildings. Due to the differences in industrial plants, It is easy for some plants to produce corrosive gas. Therefore, the natural ventilator needs to meet the ventilation needs of the indoor plant, and also needs anti-corrosion functions to ensure that the equipment is not corroded. In order to solve the above problems, the frame, rain shield tie rods, flashing plates, gutters and outer guards are made of aluminum alloy, and the rain shields are made of color-coated steel plates to eliminate the corrosion of natural vent.

During the production and processing of warehouse roof ventilation, derusting machines are used to remove rust on the profiles to further improve the anti-corrosion ability of the natural ventilation system. As a smoke vents supplier, Mcwell also can produce smoke exhaust ventilator, which can be installed in parallel on the roof or installed across the plant on the ridge of the building. No matter which type and installation form of natural ventilator, they need to be anti-corrosion to ensure the normal development of production activities of steel structure workshops.
