Before installing metal roofing panels, check the specifications, models, geometric dimensions, appearance, board length, and quantity of the metal roofing panels entering the site, and check the phototypesetting plate drawings one by one to make sure that you have a good idea. When installing metal roof panels, determine the location of the first metal roof panel installation according to the panel diagram, generally starting from the direction of the dominant wind direction.
After the two butyl tapes are processed, the middle of the butyl tape is filled with glass glue. The metal roof plate is overlapped with the light mining plate, and the corrugated on both sides of the light mining plate is cut off. And inserted into the roof 160mm or purlin overlap, and paste butyl tape on the top of the light plate, add structural glue in the middle, and the light plate and color steel plate together in the bracket above, to prevent water backflow.
The personnel can be seated on the steel ladder, the safety belt is hung on the purlin or the steel ladder is installed on the pull rod. Install the tie rod with pliers or hand grip the tie rod, and tighten the nut gasket with a wrench at the other end. Due to the long length of the metal roof panel, the installation process may slide, move up, or there will be individual places at the bite of the metal roof panel, etc., which should be treated and placed in time. When laying metal roof panels, reserve holes such as light panels and slope gas towers for good dimensions to facilitate the correct installation of light panels and slope gas towers in the later period.
