High-strength fasteners help build high-speed rail

With the increased market capacity of railways and subways, the market demand for fasteners is accelerating production. Although the construction of the railway can not be separated from the role of fasteners, but not all specifications and models of fasteners are suitable for railway construction, the strength of some ordinary fasteners simply can not adapt to the high-speed rail vibration, rail and subway rail traffic All require stronger fasteners. With the continuous increase in railway construction, the demand for high-strength fasteners in China will also increase rapidly.

Therefore, domestic fastener companies should gradually reduce the proportion of ordinary fasteners and increase the output of high-margin high-strength fasteners to meet market demand. According to China's “Eleventh Five-Year Plan” railway development plan and investment plan, from 2008 to 2010 there will be an average annual investment of 350 billion yuan, which will ensure that in the next two years, the compound annual growth rate of railway investment is about 20%. If we consider that the country is increasing its investment in the railway industry to ensure stable economic growth, the investment growth rate of the railway industry will further increase. It is expected that the growth of the railway industry will not be lower than 25% in the next 2-3 years. Great protection. The guaranteed growth of rail transit will undoubtedly lead to a relative increase in the growth of the fastener industry. The guaranteed growth of the entire industry does not mean that all fastener companies can enjoy their food and clothing. In order to meet the needs of industry growth, domestic fastener companies have actively adjusted the product structure, gradually reduced the output of ordinary fasteners, gradually increased the proportion of high-strength fasteners, and achieved strategic transformation.

In 2009, the State Council has approved plans for subway construction in 22 cities, with a total investment of 882.003 billion yuan. Up to now, about 27 cities are preparing to build urban rail transit, 22 of which have been approved by the State Council. According to the author's understanding, around 2015, 22 cities including Beijing, Shanghai, and Guangzhou will construct 79 rail transit lines with a total length of 2259.84 kilometers and a total investment of 88,200.03 million yuan. According to incomplete statistics, there are about 50 cities in Beijing and Shanghai, and 1154 kilometers of rail transit lines are under construction. The constant “increment” of rail transit in China can not only promote the development of the railway industry, but also to a certain extent, it will also drive related industries, such as the huge development of the fastener industry.
