Because the ridge ventilator is installed on the factory's roof, it will expose to the sun and rain. Therefore, it is necessary to focus on its anti-corrosion performance. Mcwell will focus on explaining the anti-corrosion technology of the natural roof ventilation.

1. Treatment of the skeleton profile of the roof ridge ventilator

The components of the natural ventilation system include the main frame, the secondary frame, the outer guard plate, the FRP daylighting board, the drainage groove and the electric control box, etc. The key point is the anti-corrosion treatment of the frame profile of ridge ventilator. In the process of installing metal building ridge vents, the frame will be painted. It is necessary to ensure that the surface of the frame profile is free from oil stains and rust, and is completely cleaned.

2. Oxidation resistance of metal building ridge vents

To increase the oxidation resistance of the metal building ridge vents, it is necessary to handle the cleanliness of the steel structure frame. Otherwise, the oxidation resistance of the roof vents will be reduced. Even if it has been painted, it will be affected in a short time. Falling off directly causes the steel frame to be exposed to the air, which accelerates the corrosion of the ventilator and reduces the service life of the ridge ventilator.

3. Anti-corrosion technology of natural roof ventilation

Mcwell's ridge ventilator will be treated with hot-dip galvanizing for anti-corrosion treatment. The frame is formed by welding, paying attention to the details and quality, including the treatment of the welding part and the end part of the profile. The ventilator frame processed by the hot-dip galvanizing process has good oxidation resistance and corrosion resistance, which increases the service life of the ventilation skylight.
