Aluminium is the main metal material. From the production of luxury goods to the common metal used in millions of households, there are many types of aluminum products, a wide range of applications, and a high degree of industrial relevance. In economic construction, national defense construction, social development, and stable employment Play an important role. And the closest to people is the application of aluminum in construction. Aluminium is a young metal material, and its natural advantages make it jump to become the second largest metal material after steel in human applications after its history of more than 100 years. The modern world has entered a new era of lightweight materials. Aluminum alloy, light, high specific strength, corrosion resistance, high recyclable recovery rate, low energy consumption for recycling, rich in resources, aluminum can play a major role in the development of a low-carbon economy, and the environmental protection of aluminum makes it important Basic raw materials. Aluminum itself is not a "two highs and one capital" product, but a metal material that is essential for the national economy and human life. Aluminum is a young Chaoyang metal material. The aluminum industry is a Chaoyang industry. In the era of lightweight materials, aluminum is the main metal material. Aluminum and aluminum alloys are mainly used in castings and die-castings. After die-casting, they can be used as parts after a slight mechanical processing. There are also processed aluminum materials, plates, strips, foils and tubes, rods, shapes, and semi-finished products. The application fields of 的 aluminum are extremely broad. Aluminum is everything that humans eat, live, and travel. No matter in China or abroad, the biggest application of aluminum is in the field of construction. Chinese construction aluminum profiles account for 70% of the output of aluminum extrusions and about 38% of the output of aluminum, plus plates and foils in aluminum products. The amount of wood used in construction is close to or exceeds 50% of the total aluminum. Houses, industrial plants and warehouses, shopping malls and shops, offices, hotels, hotels, sports and entertainment facilities, government and public facilities, multi-purpose buildings (complex buildings) and other buildings are all used for aluminum. 30Thirty years of reform and opening up, China's economic construction has developed rapidly, and the construction industry has stimulated new growth in China's aluminum industry. Building aluminum is not only aluminum doors and windows. Building aluminum profiles are by no means low value-added products. As the requirements of building height, function, and energy saving continue to increase, the requirements for building aluminum are also higher and stricter. The good thermal conductivity of aluminum is not conducive to building energy conservation, but the existing insulated aluminum profiles and insulated aluminum doors and windows have been adapted to the requirements of building energy conservation, and they maintain the light weight of aluminum doors and windows, the small load of the building wall, fire resistance, and the multi-color of aluminum. Easy to form and other advantages, aluminum-wood composite doors and windows and other applications are even more grade. The various surface treatments of aluminum are more in line with the various decorative requirements. The materials of doors and windows include wooden doors and windows, steel doors and windows, aluminum doors and windows, plastic doors and windows, color steel doors and windows, glass steel doors and windows, and composite doors and windows. In 2009, aluminum doors and windows accounted for 55% of Chinese architectural doors and windows. In 2004, the main consumption of aluminum extrusion materials in North America was for building structures, accounting for 33.7%. Applications of aluminum in construction are: aluminum doors and windows, building curtain walls, roofing, structures, courtyards, etc., with aluminum profiles-aluminum extrusions, aluminum profiles, aluminum pipes, aluminum rods; aluminum plates-aluminum rolled materials, aluminum Veneer, aluminum-plastic panel, aluminum honeycomb panel, building interior and exterior decoration, ceiling, suspended ceiling, balcony, courtyard railing. Broadly speaking, bridges-river bridges, pontoons, pedestrian bridges-flyovers, platforms for various auto shows, etc. Curtain walls, roofs, and sunshades are increasingly used. Veneer, aluminum-plastic composite panels, aluminum honeycomb panels, continuous oxidation coloring and roll coating of roll materials are advancing with the times, and continue to adapt to more and more advanced and higher requirements for buildings, including Its quality, variety and cost. China has formed and established a diversified, multi-layered, and multi-typed product structure framework for doors, windows, and curtain walls, forming a colorful urban landscape. Aluminum structure is also a large class of applications. It has developed very colorfully abroad, and China has yet to develop. Steel is "H" steel, and now aluminum is also used to produce "H" steel for building structures. Aluminum has light specific gravity, high specific strength, good corrosion resistance, colorful surface treatment, extremely high recyclability, and reduced ground load. Domestic "H" aluminum has been successfully applied in the Shanghai F1 Circuit and the Expo China Botanical Garden. There are three pedestrian crossings built in the city: Beijing Xidan, Shanghai Xujiahui, Hangzhou Qingchun Road. China's aluminum industry has taken off in the past 30 years due to the development of China's construction industry. Previously, China had a weak foundation and a large number of "debts". Therefore, after the reform and opening up, construction will enter a high-speed development immediately. It has not yet reached its peak. In the long run, it's just a matter of speed. Since 2000, China has gradually evolved from the priority development strategy of the coastal areas to the development of a balanced strategy. In 2000, it began to develop the western region. In 2001, it proposed urbanization development goals, and then proposed "the revitalization of the old industrial bases in Northeast China" and "the strategy for the rise of central China." Since 2000, the strategy of increasing investment in inland and backward areas has been increased. On May 28, 2010, Hu Jintao presided over a meeting of the Political Bureau of the Central Committee of the Communist Party of China to study "overall ideas and policy measures for the in-depth implementation of the western development strategy." China's urbanization rate was 45.68% in 2008. It will continue to grow to 47.93-53.37% in about 13 years. Public facilities and housing construction will continue to develop. The goal of urbanization and cities is "to make life better". The needs of China's urbanization development, the development opportunities of the building aluminum industry are still very bright, the key lies in grasping
