Aluminum-magnesium-manganese roof panels have many advantages such as corrosion resistance, beautiful appearance, light weight, high strength, and easy processing and forming. They are widely used in airport terminals, aircraft maintenance depots, stations and large transportation hubs, conference and exhibition centers, stadiums, etc. Exhibition halls, large-scale public entertainment facilities, public service buildings, large-scale shopping centers, commercial facilities, residential buildings and other buildings.
The 270° occlusal process of this kind of roof panel is made by automatic occluding machine to buckle and bite the double-sided single support fully automatic professional operation. Physical displacement caused by shrinkage. This advantage is reflected in the fact that the long-span roof system with long longitudinal length is not deformed by internal and external forces. At the same time, the complete accessories supply of this roofing system can meet the requirements of various building forms.
Aluminum metal is extracted from nature through electrolysis, and then combined with quantitative copper, manganese, magnesium, silicon, zinc and other elements through smelting to form a variety of alloys, which can obtain mechanical and physical properties that can meet various needs . At present, nine series of deformed aluminum alloys from 1000 to 9000 are stipulated, which are used in consumer products, aerospace, construction, packaging, transportation, electrical equipment and other aspects. It has the following characteristics:
1. Light weight. The density of aluminum is 2.73g/cm3, which is only 1/3 of that of steel.
2. High intensity. Through aluminum alloy configuration, processing and heat treatment methods can achieve high strength, and even the structure of large passenger aircraft can be built.
3. Corrosion resistance. Aluminum metal is a reliable and durable outdoor building material. It has the ability to self-anti-rust. In the natural environment, a thin and dense oxide layer can be formed on its surface to prevent the metal from oxidizing and rusting in the air. At the same time, it also resists a variety of acid corrosion. Ability.
4. The surface treatment is diverse and beautiful. It can be anodic oxidation, electrophoresis, chemical treatment, polishing, painting treatment.
5. Easy to produce, process and shape. Extrudable profiles, drawing, rolling, punching, spinning, rolling, casting and forging. Aluminum plates can be rolled into various thicknesses, even extremely thin aluminum foils.
6. Good electrical conductivity. c Non-magnetization and low electric spark sensitivity, can prevent electromagnetic interference and reduce flammability in special environments.
7. Easy to connect. Aluminum metal can be connected by riveting, welding, gluing, etc.
8. Recyclable. The value of aluminum recycling is very high, the long-term use cost is relatively economical, and it plays a positive role in saving natural resources.
