In the past 30 years, with the rapid development of metallurgical industry, machinery industry, electronic industry, etc., it has promoted the upgrading of global fastener products and the continuous progress of fastener industry. Since the beginning of the 21st century, the country’s major cross-century projects-West-East Gas Pipeline, South-to-North Water Transfer, High-speed Railway and West-East Power Transmission have been fully rolled out. The domestic automobile, machinery, household appliances, shipbuilding, and transportation industries have continued to grow, and there is a strong demand for production and construction. Will drive the substantial growth of the fastener industry. According to data released by the China Machinery General Parts Industry Association, from 2015 to 2019, my country's fastener production has increased year by year, and the output in 2019 will reach approximately 8.5 million tons.Metal fasteners are the main type of fastener production in my country. According to data released by China Machinery General Parts Industry Association, my country's metal fastener production fluctuates from 2017 to 2019. In 2019, my country's metal fastener production It reached 7.4323 million tons, accounting for 87.44% of the total output of fasteners; the output of metal fasteners in the first half of 2020 was 4,664,800 tons.Fastener products are in great demand in the market. All kinds of mechanical and electrical products, all large, medium and small projects, not only require a large number of fasteners in the initial assembly and initial construction, but also all equipment and various projects are in long-term operation. , The number of fasteners required for irregular maintenance and repair is also very large, generally several times the amount of initial installation and initial construction. From the perspective of market product categories, China’s fast-growing automobile industry, home appliance industry, electric power industry, transportation industry and many major and large projects urgently need all kinds of high-strength, high-precision, and high-performance fasteners. It is foreseeable. The domestic demand for fasteners will grow rapidly in the next few years.
