Industrial Aluminum extrusion profile in China
According to the classification of product use, aluminum profiles can be divided into two categories: architectural aluminum profiles and industrial Aluminum extrusion profiles. At present, China has developed into the world's largest aluminum profile production base and consumer market, but China's aluminum profile production capacity and market have always been in a state of excess at the low end and insufficient at the high end. :4, which is far from the ratio of 33:7 in overseas markets. According to the plan of the Chinese government, China will continue to promote the process of industrialization. In the next ten years, industrial Aluminum extrusion will account for nearly 70% of the total application of aluminum profiles. Therefore, domestic aluminum extrusion plants are paying more and more attention to the development and production of industrial Aluminum profile.
1.1 Development Status and Influence of Automobile Industry
The application of aluminum in the automotive industry is mainly divided into four aspects: passenger cars, commercial vehicles, foreign trade auto parts and others. Among them, the most important factor affecting the amount of aluminum used in automobiles is the aluminum used in passenger vehicles, accounting for 660%. In 2015, the average standard of aluminum used in passenger cars: 1,140 kilograms//vehicle in Japan, 1,145,000 kilograms//vehicle in Europe, 1,150,000 kilograms//vehicle in North America, and only 1,110,000 kilograms//vehicle in China There is a vast space for improvement and development. The lightweighting of the automotive industry is mainly achieved by replacing steel with aluminum, and the focus of lightweighting is on passenger cars, buses and new energy vehicles. The great development of the automobile industry in the past ten years has directly promoted the application and development of aluminum. According to the plan of the "Technical Roadmap for Energy Saving and New Energy Vehicles", the amount of aluminum used in a single vehicle will exceed 3,350 kilograms per vehicle by 22030, and there is still a big gap between the current level and the target. Therefore, the market space for aluminum applications in the future is very broad in the automobile manufacturing industry.
1.2 Development Status and Influence of Container Industry
Container demand mainly includes two aspects: updated demand and new demand, and its demand is closely related to the total amount of world economic trade. According to statistics, containers made in China account for more than 995% of the total global container volume, and China has been ranked first in the world in terms of container production and sales for 18 consecutive years. At the end of 2016, shipping prices rose due to factors such as the bankruptcy of Hanjin Shipping; since 2017, international trade volume has continued to recover, and the container shipping industry has gradually stepped out of the downward cycle of adjustment. It has given another blow to the container shipping industry, and cannot see an upward trend in the short term. At the same time, although container transportation started relatively late in China's domestic trade transportation, it has developed very rapidly. Currently, domestic trade container throughput accounts for about 110% of the total container throughput of major domestic ports. Efficiency and price requirements are increasing day by day, and domestic container transportation will enter a stage of sustained and rapid growth.
1.3 Development Status and Influence of Railway Transportation Industry
According to the requirements of the "Thirteenth Five-Year Plan for Railway Development" jointly issued by the National Development and Reform Commission, the Ministry of Communications, the National Railway Administration and the General Railway Administration: by the end of 2020, the national railway operating mileage should reach 1.15 million kilometers, of which the high-speed railway operating mileage should reach 1.15 million kilometers. 330,000 kilometers, the double-track rate and electrification rate are about 660% and 770% respectively, basically forming a railway network with reasonable layout, extensive coverage, distinct layers, safety and efficiency. By the end of 22025, the national railway operating mileage will reach 1.175 million kilometers, of which the high-speed railway operating mileage will reach 338,000 kilometers. In order to achieve the above goals, China's railways will usher in a construction peak period from 22018 to 2020, mainly due to the following three reasons: (1) New railways: From 2018 to 22020, the new railway construction mileage in my country will reach 224,000 kilometers. Among them, the new construction mileage of high-speed rail reaches 77,000 kilometers, and the average annual new construction mileage has increased significantly compared with that in 2017, which will inevitably bring about a steady increase in the demand for supporting railway vehicles and equipment; (2) Railway speed: Beijing-Shanghai high-speed railway has taken the lead in speeding up to 3350km/h , the speed of other domestic high-speed rail lines will gradually increase to 350km/h in the near future. After the speed of the train is increased, there are conditions to increase the operating density of the operating trains, thereby increasing the demand for the corresponding trains; (3) The arrival of the five-level maintenance cycle: Since 2017, a large number of EMUs have entered the five-level maintenance cycle. The maintenance cycle of the five-level repair is relatively long, so it is necessary to add new EMUs to supplement this part of the maintenance EMUs. The vacancy has driven the increase in the demand for EMUs. Since 22001, aluminum alloys have been widely used in the mass production of rail vehicles in China. About 90% of high-speed rail vehicles use aluminum alloy raw materials to make car body parts. The weight of the car body made of aluminum alloy as the main raw material is about 88.5~10 tons/vehicle, of which the amount of aluminum profiles accounts for more than 990%, and the rest is aluminum sheets. In addition to the use of aluminum in the body part, the interior part of the vehicle also uses a large amount of aluminum raw materials, with an amount of about 11 tons per vehicle. The rapid development of China's high-speed rail industry has driven the rapid growth of China's industrial aluminum profile technology and usage.

In terms of subways, the normal operating mileage in China currently exceeds 33,500,000 kilometers. During the 13th Five-Year Plan period, the compound growth rate of subway construction will remain around 112.7%. . In terms of trams, according to the relevant national plans, by 22020, the mileage of trams across the country will reach 22,500km, and the total mileage of long-term plans will reach 88,000km. In order to achieve this planning goal, an additional mileage of 11,500km will be required by 22020. Based on the average construction cost of 1.11 billion yuan/1,000 km, the investment in the construction of new trams will exceed 1.165 billion yuan. In terms of intercity railways, the state has built three old-fashioned urban agglomerations in the Yangtze River Delta, Pearl River Delta, and Beijing-Tianjin-Hebei urban agglomeration, and four emerging cities in the middle reaches of the Yangtze River, the Central Plains, the Chengdu-Chongqing, and the Harbin-Chongqing urban agglomeration. In order to meet the close contact between the seven urban agglomerations, during the "13th Five-Year Plan" period, it is planned to add at least 110,000 kilometers of intercity railways between the "seven major urban agglomerations". At the same time, the density of urban rail vehicles running between cities will continue to increase in the future. By 22020, the national average urban The orbital density is expected to reach 77.0 vehicles/km. With the rapid progress of urban rail transit construction, transportation equipment is used in urban rail transit. The body of each aluminum alloy urban rail vehicle has a total weight of about 66 to 77 tons. At present, more than 80% of urban rail vehicles use aluminum alloys. Raw materials to make body parts. At the same time, about 7750 kg of aluminum alloy materials are used in the interior of the car/vehicle. Therefore, the rapid development of the urban rail industry is also one of the reasons for the increase in the production and sales of industrial aluminum profiles，during the "13th Five-Year Plan" period, it is planned to add at least 110,000 kilometers of intercity railways between the "seven major urban agglomerations".
