Aluminum Spiral High Speed Door
The Spiral door offers high-speed operation for high-traffic situations and rigid aluminum slat construction that eliminates the need for a second security door. Crisp lines give the Spiral door a stylish look that's great for many types of commercial, automotive retail, government, institutional and industrial applications. The Spiral is ideal for automotive dealerships, government, parking and security. Benefits No metal-to-metal contact reduces wear on the door panel and offers fast, quiet operation.
Aluminum spiral High Speed doors are usually used wherever goods traffic occurs and where the doors have to fulfill special requirements. In the food and beverage industry, or Medical industry for example, special climatic conditions have to prevail; short opening and closing times reduce cooling loss, avoid airflow and enable a smooth operating procedure. They can also be designed in larger dimensions for the mining and aircraft industries.

According to the national “13th Five-Year Planâ€, the high-speed railway network should be improved in the next five years. In addition to the continuous high-speed railway from Lianyungang to Urumqi, a large number of high-speed railway links from Beijing to Hong Kong (Taipei) will be built to expand the regional connection line. During the “Thirteenth Five-Year Plan†period, the mileage of high-speed railway will reach 30,000 kilometers, and the number of new high-speed railways will reach 11,000 kilometers in the next five years, covering more than 80% of cities.
The "four vertical and four horizontal" high-speed rail network is more intensive. The north-south high-speed rail has increased the number of lines from Hohhot to Nanning and Baotou to Haikou. The east-west high-speed rail has increased the routes from Xiamen to Chongqing. The above-mentioned high-speed rail belongs to the "13th Five-Year Plan" major project.
Wang Mengshu, a deputy to the National People's Congress and an academician of the Chinese Academy of Engineering, believes that railway investment during the 13th Five-Year Plan period may require more than 4 trillion yuan.
"13th Five-Year" high-speed rail expansion
The “13th Five-Year Plan†proposes to build Beijing to Hong Kong (Taipei), Hohhot to Nanning, Beijing to Kunming, Baotou Yinchuan to Haikou, Qingdao to Yinchuan, Lanzhou (Xining) to Guangzhou, Beijing to Guangzhou, Chongqing in the next five years. To Xiamen and other high-speed railway channels.
The Medium and Long-Term Railway Network Plan, adjusted by the National Development and Reform Commission in 2008, proposes to build a “four vertical and four horizontal†high-speed rail network by 2020. The “four verticals†refer to the Beijing-Shanghai, Beijing-Guangzhou, Jingha, and Southeast coastal passenger lines. "Horizontal" refers to the passenger line of Bohai, Shanghai Kun, Qingtai and Hu Hanrong.
According to the “Thirteenth Five-Year Planâ€, there are more than eight horizontal high-speed rail lines. There are mainly high-speed rail from Mudanjiang to Qiqihar, Beijing to Baotou, Qingdao to Yinchuan, Lianyungang to Urumqi, Shanghai to Chengdu, Shanghai to Kunming, Xiamen to Chongqing, and Guangzhou to Kunming.
There are more than 10 vertical trunk lines, namely, coastal high-speed railway, Beijing-Kowloon, Beijing-Guangzhou, Beijing to Fuzhou, Hohhot to Nanning, Baotou to Haikou, Yinchuan to Kunming, Beijing to Kunming, Yinchuan to Xiamen, and Xi'an to Guangzhou.
The Baohai high-speed rail is Baotou-Xi'an-Chongqing-Guiyang-Nanning-Haikou, which is different from the situation when the Baohai high-speed rail was originally proposed by Enshi, Jishou and Huaihua.
Peng Qiyuan, dean of the Jiaotong University of Southwest Jiaotong University, believes that the Baohai high-speed rail mainly passes through the provincial capital cities because the provincial capital cities are mostly transportation hubs, and the passenger flow is very large, which can exert the maximum effect of the high-speed rail.
“Baohai high-speed railway goes to Chongqing and Guiyang. I think it is mainly considered from the dense layout of the route. The layout of the provincial capital is better. Because the high-speed railway has to bear the role of the main large-scale channel, there must be passenger flow,†he said.
Wang Mengshu, an academician of the Chinese Academy of Engineering, pointed out that it is necessary to build the above-mentioned railway into a network. For example, Dalian to Yantai submarine high-speed rail repair, from Harbin can go straight to Shanghai, the line is conducive to the economic development of the Northeast. After the Zhanjiang-Haikou high-speed rail is repaired, tourists can enter Hainan via the high-speed rail around the island to travel to the island.
Vertical and horizontal trunk encryption
The high-speed rail line of the 13th Five-Year Plan is more than doubled than the high-speed rail line proposed in the Medium- and Long-Term Railway Network Plan adjusted in 2008.
Peng Qiyuan believes that all modes of rail transit should be developed together. Apart from high-speed rail, subways, light rails and trams in various cities are necessary to develop. Of course, it depends on whether there is demand in the city. At present, the number of cars in China has increased rapidly. Even in small and medium-sized cities, traffic jams have occurred. From the perspective of environmental protection and ease of traffic pressure, the development of urban rail transit is the right direction.
According to the national “Thirteenth Five-Year Planâ€, China will build the Hetian-Ruoyu Railway, the Northeast Boundary Railway and the Sichuan-Tibet Railway along the border railway in the next five years to promote cross-border passages with neighboring countries and the construction of the “Belt and Road†corridor.
In addition, it is necessary to build a 1-2 hour traffic circle between the central city of the urban agglomeration, the central city and the neighboring nodes, and create a one-hour commuter metropolitan area between the central city of the urban agglomeration and the important surrounding towns, and basically complete the Beijing-Tianjin-Hebei, Yangtze River Delta, and Pearl. The intercity railway network of the urban agglomerations such as the triangle, the main skeleton of the intercity railway network of other urban agglomerations, and the demonstration project of the city (suburb) railway.
It will also improve and optimize the super-large and mega-city rail transit network, accelerate the construction of urban rail transit with a population of more than 3 million, and increase the mileage of urban rail transit operations by about 3,000 kilometers.
Zhang Jiangyu, a senior railway planning expert, believes that the railways built during the 13th Five-Year Plan period are not only the contents of the current planning, such as the Tibet-Tibet Railway.
In the future, if the urban population is over 1 million, the city express railway will be built. The city express line is long and the cost is only one-fifth to one-third of the subway, which is relatively cheap. Zhang Jiangyu believes that all the megacities can repair such a city express line in the far-reaching areas. During the "13th Five-Year Plan" period, the city express line may be a bright spot for faster growth and better construction momentum.
The 13th Five-Year High-speed Railway will expand its mileage by 11,000 kilometers in the next five years.
