MN73 roofing system adopts 360 degree vertical edge locking technology. The roofing plate is pre-rolled 270 degrees in the factory, and then the roof plate and sliding support are connected together on site to form a preliminary self-locking 270 degrees, which has a certain wind resistance ability to ensure the safety of construction and can minimize the cracking of coating and paint layer during the occlusal process. The vertical locking technology of Meney construction can ensure the tightness of the rolling edge, prevent the rain from entering, and will not destroy the coating. Moreover, there is factory preset glue in the rolling edge, which can help prevent capillary seepage and form a firm water defense line.
