With the implementation of energy saving and emission reduction and the application of natural roof ventilation in various factories, many problems of natural ventilation system have emerged, such as roof leakage, roof crushing, roof rust, etc., Mcwell will introduce how to project roof surface when install natural vent.

The installation of natural roof ventilation is generally done on the color-coated steel plate on the roof. Because the steel structure roof which the roof louver vent is placed requires a corresponding work surface. But need to pay attention to that: the anti-corrosion layer on the surface of the color-coated steel sheet on the roof is only tens of microns. When mechanically hoisting parts such as the smoke vents frame and the outer guard plate, the friction between the components and the color-coated steel sheet on the roof will easily cause damage natural ventilator's surface paint, anti-corrosion coating and other scratches, the service life of the color-coated steel plate after scratches will be reduced.

In view of the above possible problems, Mcwell's specific protection measures for the color-coated steel plate on the surface of the steel structure factory include:

1. For large components, before hoisting the raw materials and semi-finished products, place sleepers in the slope valley of the roof panel. The height of the sleepers is higher than the slope peak of the roof panel. On the square platform, the force is transferred from the framework to the platform, the platform is transferred to the sleepers, and the sleepers are transferred to the horizontal bars of the roof panel and the roof steel beams, thereby completely protecting the roof color-coated steel plate.

2. For small components of a ventilated building, carpet or canvas is laid on the roof to avoid direct contact between the components and the roof panel and reduce friction.
