Al-Mg-Mn сплава кровельных плиты

Product Name: Al-Mg-Mn alloy roofing plate Al-Mg-Mn alloy roofing plate is widely used in building materials industry, and it greatly contributes to the modern building industry in terms of conform, lightness, durability, economy, environment protection direction play an important role. This Multi-layer composition system contains six parts.including standing seam roofing plate,T type base,aluminum foil-gas barrier,extrusion foam board,perforated plate and purline. Al-Mg-Mn alloy roofing plate characteristics: 1. Low weight. Aluminum density accounts for 2.73g/dm3, only 1/3 of steel's. 2. Long life time,more than 50 years . 3. High strength. through proper composition, fabrication and heat treatment, very high strength can be acquired. 4. Corrosion resistant, rust proof; The naturally-formed oxide layer can prevent metal from oxidization and have good acid and alkali resistance. 5. Various surface finish and elegant appearance. The material can be anodized, electrophoresis-treated, polished or coated. 6. good formability and easy to be processed. 7. Good electric conductivity. Non-magnetization and low electric spark sensitivity, can avoid electromagnetic interference and reduce inflammability. 8. Easy installation. Aluminum alloy could be riveted, welded and glued, or connected by any other methods. 9. Environmental, 100% recyclable.
