The basic parts represented by fasteners are not only the basic industries of China's equipment manufacturing industry, but also an important foundation for all fields of national economic construction. During the “12th Five-Year Plan†period, the industry must rely on new advantages such as technological advancement, quality improvement, and product cost-effectiveness to achieve sustainable development while maintaining some cost advantages. It is expected that the total output of the industry will reach 7.5-8.0 million tons by the end of 2015. Under the overall situation of expanding exports, export products will assume a fluctuating growth trend. It is expected that the average annual export growth rate during the 12th Five-Year Plan period will be 8% to 10%. By 2015, the total export value of the whole industry will reach 30 billion Yuan.
The domestic market will continue to maintain a good momentum of growth in areas such as automobiles, agricultural machinery, high-speed railways, metallurgy, electric power, construction machinery, and infrastructure. This will bring about a broad market space for the growth of demand for fasteners.
1 Automobiles, it is expected that by the end of 2015, China's auto production and sales will both exceed 23 million. According to statistics, a light vehicle or passenger car fastener is about 500 specifications, 50kg, 400 pieces; and a medium-sized or heavy truck commercial vehicle requires about 7500 pieces of fasteners and a mass of 90kg. Calculated according to 70kg per vehicle, the annual demand for automotive fasteners is over 1.5 million tons.
2 Wind power, domestic market demand for megawatt wind turbines is very urgent, the national plan to 2015 wind power installed capacity to reach 70 million KW, and maintain a new rate of not less than 14 million KW per year. The demand for high-strength fasteners for wind turbines is calculated at 400kg per KW, and over 500,000 tons of high-strength fasteners are required for wind power.
3Nuclear power According to the national mid- and long-term plan, by 2020, China will start construction of more than 40 million nuclear power plants, and the total size of nuclear power will be equal to the current 20 Daya Bay nuclear power plants. More than 8.8 high-strength nuclear power special fasteners, special materials, fasteners, welding rivets products demand more than 8 to 10 million tons.
4 Agricultural machinery, the total output value of a series of agricultural machinery products such as tractors, rice transplanters and harvesters during the “Twelfth Five-Year Plan†period will reach 250 billion yuan. It is estimated that annual demand for various kinds of standard parts and fastening special-shaped articles will be more than 150,000 tons, and the output value will be about 20 100 million yuan.
5Construction machinery, during the "12th Five-Year Plan" period, the social machinery loader for construction machinery loaders, excavators, road rollers and other products will reach 6 million units, and the annual sales volume will be around 50,000 units. It is expected that the annual demand for high-strength fasteners will be 2~ 30,000 tons.
6 High-speed rail, the high-speed railway, passenger dedicated line and inter-city rail transit will increase rapidly during the 12th Five-Year Plan period. It is estimated that the annual capital investment will be 300-400 billion yuan, and the annual demand for high-speed rail fasteners will be nearly 300,000 tons.
7 The maintenance and new construction of power, various grades of high-voltage, ultra-high voltage transmission towers will greatly increase the demand for electrical fasteners, and will require nearly 220,000 tons per year.
During the “Twelfth Five-Year Plan†period, China’s fastener industry is faced with historical development opportunities of adjustment and rejuvenation, and from big to strong, domestic and foreign market competition has intensified, and domestic deep-level contradictions will inevitably affect the pace of advancement of the industry, but promote industrial technological progress and innovation. The basic strength of development is irreversible, and the entire industry will achieve stable growth with an average annual growth rate of 15% to 18% in the process of transformation and upgrading.
