For the correct installation of polycarbonate honeycomb sheets, it is necessary:
The canopy must have a minimum slope of 5%
The ribs must always be placed in the direction of the slope of the canopy (the ribs of the polycarbonate sheet follow its longest dimension)
Because the sheets offer protection from ultraviolet UV radiation only on one side, this side should be exposed to the sun (it is the side with the letters of the protective film)
The protective films of the polycarbonate sheets should be removed shortly before or during their installation, because their prolonged exposure to the sun affects them, resulting in them not detaching from the material
The polycarbonate sheets should always be curved along their length
For the correct storage of polycarbonate honeycomb sheets:
If they are not used immediately, they should be stored in a place that is not exposed to direct sunlight
Otherwise - and especially if left horizontally on cement slabs or similar materials - high temperatures develop, resulting in their warping
