Construction machinery bridges the development of fasteners

China's fastener industry has been accelerating its pace of adjustment, pursuing a one-sided pursuit of output value output, improving the quality and brand effect, and pursuing a one-sided pursuit of transformation from a production-oriented model to a production-oriented model. Therefore, the concentration of the fastener industry has become apparent. Initially formed three major fastener industry clusters in the Yangtze River Delta, the Pearl River Delta and Bohai Bay, and built a number of fastener industry bases such as Jiaxing, Ningbo, Wenzhou, Suzhou, Dongguan, Hebei Xingtai, and Yongnian.

The huge market for construction machinery paves the way for the development of the fastener industry. The machinery industry is China's largest industrial sector. In 2011, China's machinery industry realized a total industrial output value of 16.89 trillion yuan. According to customs statistics, from January to November 2011, The import and export of machinery industry was 574.557 billion U.S. dollars, an increase of 24.09% over the same period of last year. Among them, the import value was 283.023 billion U.S. dollars, an increase of 23.34% year-on-year; the export volume was 291.534 billion U.S. dollars, an increase of 24.83% year-on-year; the import and export trade surplus was 8.517 billion U.S. dollars.

Fasteners are also the main basic parts of the machinery industry. The development of the machinery industry places higher demands on fastener products. According to reports, during the 12th Five-Year Plan period, the number of construction machinery such as loaders, excavators, and road rollers will reach 6 million units, and the annual sales volume will be around 50,000 units. According to this estimate, the annual demand for high-strength fasteners is about 20,000 yuan. ~ 3 million tons. The urban rail transit infrastructure construction involves many related industries, including railway equipment manufacturing, high-speed railway bearing railway communication engineering optical communication equipment, railway engineering construction and construction machinery, etc. The construction of these projects will bridge the development of fasteners. Take the road.

Including loaders, excavators, truck cranes, road rollers, forklifts, bulldozers, and concrete machinery, a large number of engineering machinery products have leapt to the top in the world, and China has become a truly world-renowned engineering machinery manufacturer. The rapid development of the machinery industry and the huge market size provide a broad space for development for the fastener industry. However, due to China's relatively late recognition of the importance of mechanical parts in the machinery industry and the lack of investment for a long time, the entire industry has a poor foundation, a weak foundation, and weak strength. In particular, with the increase in the level of China's host computer, bottlenecks that mechanical components lag behind the host are becoming increasingly apparent. In recent years, although the fastener industry has given certain support in terms of technology introduction, technological transformation, research and development, etc., there is still a small gap compared with current market demand and foreign standards.

At present, domestic ordinary standard fasteners have been oversupply, while high-grade fasteners are in short supply and rely on imports. High-strength fasteners With the improvement of the industrialization level and technological progress of the country, the usage has gradually increased. The basic parts represented by fasteners are not only the basic industries of China's equipment manufacturing industry, but also the important foundations for various fields of national economic construction.
