How to choose the roof panel to ensure the service life of the house roof?
We all know that the anti-corrosion performance of roofing materials directly affects the waterproof, beautiful and durable functions of the roof, especially the anti-corrosion performance of the roof panel, which is also related to the service life of the roof. The editor has often heard customers complain that the resin and color steel tiles that were replaced in the past few years have been leaking in the past two years, which is really worrying. How to choose the roof panel to ensure the service life of the house roof?
Aluminum-magnesium-manganese roofing aluminum-magnesium-manganese metal plates have become very popular in recent years, and there is much online propaganda saying that they are durable. So, how many years can it be used, and how can the roof's service life be extended? Let’s analyze it together Bar
The house uses galvanized, aluminum-zinc or resin as the roof panel, and its base material does not have any anti-corrosion ability. Therefore, the decorative parts of the profiled steel roof and screws will rust quickly because there is no coating protection, and the protective layer on the surface may be damaged in multiple links such as production, loading and unloading, transportation, and installation. The local corrosion that causes it will gradually spread once the profiled steel plate has local corrosion, affecting the beauty and waterproofing of the roof.
Aluminum-magnesium-manganese roof panels and aluminum-magnesium-manganese plates are made of high-quality aluminum-magnesium-manganese alloy material, and its base material has strong corrosion resistance, especially in an acidic environment, its corrosion resistance is much higher than that of the steel plates and ordinary aluminum alloy plate. According to relevant standards, its service life in ordinary environments is not less than 50 years. Since the bottom layer is covered with roof panels, it is not eroded by wind, rain, and sunlight, so the environment is good. Taking into account the economy and applicability, the screws used in the roofing system are all high-quality screws, and the accessories are all high-quality aluminum alloy accessories. Therefore, the roofing system has good anti-corrosion ability from the roof slab, and the bottom floor slab to the screw purlins and accessories, so as to ensure that the service life of the entire roofing system will not be affected by the weakness of a certain link.
There are also aluminum-magnesium-manganese roof panels. The aluminum-magnesium-manganese panels are fixed by vertical seaming. When changing, it can expand and contract freely on the fixed seat without generating thermal stress. This helps to solve the temperature deformation problem that other panel types are difficult to overcome, and ensures the firmness of the roof performance. In addition, at the opening of the roof and the connection between the aluminum-magnesium-manganese plate and the skylight, the joints can be fastened by welding flashing, so that the roof plate can still be freely stretched and unconstrained in these places.
It can be seen that the roof's life is not only due to its building materials but also to the installation method.
