Why can aluminum-magnesium-manganese-aluminum prefabricated houses be popularized and applied?

After years of development, Al-Mg-Mn-Al prefabricated houses have been significantly improved in product quality and appearance, energy saving and environmental protection, economy and practicality. At present, more and more people use aluminum mobile homes. Aluminum alloy mobile home has become an indispensable building product for temporary living environment. Nowadays, people's lives are gradually improving, and they are all eager to have a beautiful earthquake-resistant house. At present, the aluminum mobile house building is not a traditional foam composite board, but a new thermal insulation and fire-resistant rock wool composite board. The rock wool composite board has the advantages of fireproof, waterproof, good thermal insulation performance and long service life.

With the continuous progress of science and technology and the sustainable development of society, the good performance of Al-Mg-Mn-Al mobile house is more and more accepted by people, and its function is more and more perfect. In the current social environment, the better the energy and performance of aluminum mobile homes, which meets people's needs.

Most of the dormitories on the construction site use aluminum-magnesium-manganese mobile homes, and the aluminum-plate mobile homes are mainly used as temporary offices and dormitories on the construction site. Buildings for exploration and operation of large and medium-sized oil fields such as railways, transportation, water conservancy, petroleum and natural gas; City municipal temporary commercial or other buildings; Leisure villas and holiday houses in tourist areas; Earthquake relief and military buildings.

The aluminum-magnesium-manganese-aluminum prefabricated house can be disassembled at will, which is convenient for transportation and movement. Mobile homes are suitable for hillsides, hills, grasslands, deserts and river banks. It does not occupy space and can be built in the range of 15 ~ 160 square meters. The activity room is clean and sanitary, with complete indoor facilities, high stability and durability, and beautiful appearance, which can be designed according to customers' requirements. The appearance is beautiful, the heat preservation performance is good, and it is warm in winter and cool in summer. Most of the structures of the activity room will be manufactured in the factory and installed on site. It will not damage the environment, it not only has practical value, but also has ornamental value, and can be popularized and applied.
