· After the laying is completed, reserve the position of the lighting board, and the construction is gradually carried out from the cornice to the ridge. The lighting panel is directly buckled on the side crest of the steel plate.
· Before fixing the lighting tile, the pilot hole must be larger than 6-9mm of the diameter of the fixing screw for thermal expansion and contraction.
· When the lighting tile and the steel plate are overlapped longitudinally, there must be a minimum overlap of 200mm, and two waterstops should be attached.
· When the lighting tile is fixed, a good flashing washer must be used, so that it is between the screw and the lighting board, so as to be waterproof and dustproof.
· After inserting the flashing washers into the screws, use an electric drill to lock them into the purlins to complete the fixing of the lighting panels.
· During the construction of the lighting tile, it is strictly forbidden to step on the crest of the wave directly, so as to avoid the cracking of the lighting board. A 1200mmx300mm {length x width) non-slip thick wooden board must be placed in the lateral position of the lighting board, and the guide holes and fixing screws of the lighting board must be stepped on it.
