Market Analysis my country's construction steel structure started early, industry standards and specifications are becoming more and more perfect, industry talents (including design, installation, construction) have gradually formed a scale, and some high-quality companies have begun to undertake overseas projects. According to the "2015-2020 China Steel Structure Industry Market Demand Forecast and Investment Strategic Planning Analysis Report" released by the Prospective Industry Research Institute, since 2000, my country's steel structure industry has entered a stage of rapid development, and the output of steel structures has increased from 8.5 million in 2002. tons, increased to 35 million tons in 2011, with an average annual compound growth rate of more than 15%, and the output in 2012 was about 39 million tons. my country's spatial steel structure is widely used, accounting for a large proportion of steel structure applications, mainly used in urban public buildings such as large stadiums, theaters, airports, and railway stations. By 2012, the market capacity of space steel structure is about 43 billion yuan. Steel structure buildings have the advantages of earthquake resistance, light weight, and low environmental pollution, which are in line with the direction of building energy conservation and environmental protection. In developed countries such as the United States and Japan, the steel structure building area accounts for more than 40% of the total building area, while in China, this proportion Only about 5%. Therefore, the promotion of steel structure buildings will greatly expand the demand market of the steel structure industry, and this market has great development space in China. Development prospects Steel structure development: three major areas should be paid attention to. According to the development of the industry, Liu Jun believes that the development of the three areas of offshore oil engineering equipment, steel structure housing, and steel structure bridges should attract the attention of the relevant national authorities. And policy encouragement can fully achieve the goal of industrial doubling. Liu Jun pointed out that the output of offshore oil will reach 100 million tons in 2015. The goal of marine engineering equipment enterprises is to provide a large amount of equipment for the mining of deep seas ranging from 1,500 meters to 3,000 meters. The industrial level and scale must be improved; Environmental protection, energy saving and emission reduction and circular economy policies, its industrialized and standardized steel structure residential products have a broad and unlimited market space; at present, less than 1% of the 590,000 highway bridges in the country are steel structure bridges, the railway system is developing rapidly, and new lines are built. With bridges instead of roads, 80% of them are prestressed reinforced concrete bridges. While steel structure bridges account for 41% in Japan and 33% in the United States, it can be seen that there is still a big gap between the market demand and industrial development of steel structure bridges in my country and developed countries. China's steel structure industry has developed rapidly in the past 10 years, and has become the world's largest steel structure country with the largest amount of steel structure, the strongest manufacturing and construction capacity, the largest industrial scale, and the largest enterprise scale. Steel structure enterprises: Pay attention to the development of the "Twelfth Five-Year Plan" Liu Jun pointed out that the successful construction of major steel structure projects in various places shows that my country's comprehensive steel structure technology level has reached the international advanced level. However, there is still a big gap between my country's steel structure industry and developed countries in terms of informatization, automation, standardization, scientific research and innovation. 2011 is the first year of the national "Twelfth Five-Year Plan". Relevant national ministries, industry associations, enterprise groups, and steel structure enterprises are all conducting research and analysis of the market and future development trends. The National Development and Reform Commission, the Ministry of Industry and Information Technology, and the Ministry of Science and Technology are also studying the determination and planning goals of relevant strategic new industries. For industries with international advanced level, strong independent innovation ability, strong international competitiveness and can occupy more markets, they will be included in the planning and given. Support and support policies. Opportunities are also challenges. Whether my country's steel structure industry can reach a higher level and scale, the development during the "Twelfth Five-Year Plan" period is very important. Liu Jun said that after investigation and research, and after listening to the opinions and suggestions of relevant experts, the China Steel Structure Association drafted the "Draft of Strategic Thinking and Suggestions on the Steel Structure Industry in the National "Twelfth Five-Year Plan", and was soliciting the opinions of relevant personnel. After the opinions, the association will organize relevant experts to implement and improve it, so as to promote the greater development of the steel structure industry during the "Twelfth Five-Year Plan" period.
