Aluminum-magnesium-manganese roofing plate have been widely used around the world, not only because of their excellent characteristics, but also because reasonable structural levels and correct construction methods play a crucial role. The selection of structural layers for Aluminum-magnesium-manganese roofing plate can be flexibly chosen according to the geographical location, functional use, and other conditions of the building. The structural layers are mainly composed of Aluminum-magnesium-manganese roofing plate, insulation layers, and metal bottom plates, which are subdivided from bottom to top as follows:
Structural base plate: Generally, perforated aluminum zinc or galvanized profiled steel plates are used, and their thickness is designed according to the distance between the purlins. The perforation rate is calculated based on the project. Supporting sound-absorbing cotton and insulation cotton, while also serving a decorative purpose.
Roof purlins: Generally, lining purlins and steel purlins are used to provide structural support and slope making
Dust proof layer: generally made of non-woven fabric, mainly used for dust and dust isolation, laid on the surface of the roof bottom plate.
Acoustic cotton: Glass wool is usually used, and its bulk density and thickness need to be determined based on calculations.
Vapor barrier: Generally, polyester film or high-density spunbond polyethylene film is used, and glass wool (with moisture-proof veneer) can also be selected. The vapor barrier can limit the entry of water vapor inside the building into the roof, thereby avoiding condensation to the greatest extent possible.
Insulation and sound insulation layer: Rock wool is usually used, and its thickness needs to be determined according to calculations. Mainly used for insulation and noise reduction, such as the noise caused by heavy rain and hail hitting the surface layer.
Waterproof breathable membrane: It is a high-density polyethylene non-woven fabric that blocks the invasion of wind and rain on the building structure. While strengthening the airtightness and water tightness of the building, it can also provide rare breathability, allowing water inside the enclosure structure to be quickly drained, effectively avoiding the formation of mold and condensation water.
Aluminum-magnesium-manganese roofing plate: The thickness is usually 0.4mm-1.2mm. The panel is a layer that comes into direct contact with the atmosphere and rainwater. It is of great significance for the waterproof design and treatment of the surface layer. The selection of vertical height, vertical direction, and the construction of special nodes all determine the effectiveness of roof waterproofing.
Aluminum-magnesium-manganese roofing plate is a metal roofing material based on Aluminum-magnesium-manganese roofing plate, mainly used in large public buildings and villa projects such as airports and sports venues. The substrate is mostly made of 3000 series aluminum alloy, which is treated with oxidation, embossing or fluorocarbon coating on the surface. The fluorocarbon coating adopts a multi coating and multi baking process, with excellent UV resistance.
