In order to consolidate the strength of enterprises, guide technological innovation, solidly promote the implementation of the construction of a quality strong country, and promote the high-quality development of the industry, we aim to; Green, low-carbon, intelligent construction, promoting high-quality development of steel structure construction industry; The 2023 National Building Steel Structure Industry Conference with the theme of. At the meeting, the focus was on“ Dual carbon; Based on themes such as goals and intelligent construction, the latest industrial policies and the challenges faced by the steel structure industry were interpreted. Several experts and scholars shared cutting-edge technologies, new materials and processes for steel structures, future trends in steel structure building applications, technological research achievements and practical experience. They also provided suggestions and recommendations for the development and innovation of China's steel structure industry, promoting continuous innovation and upgrading of the entire steel structure industry chain
“ Accelerate the construction of a new development pattern and focus on promoting high-quality development;, As an important pillar industry of the national economy, the construction industry must vigorously develop green buildings, promote the application of green building materials, and promote new green construction methods such as prefabricated buildings to achieve high-quality development. This will have a significant impact on the future steel structure industry. Vigorously promoting steel structure buildings will force the steel structure industry to accelerate technological innovation, further improve product quality, and make greater contributions to the transformation and upgrading of the construction industry and the realization of green and low-carbon development
From a macro perspective, the fundamentals of China's strong economic resilience, ample potential, and long-term improvement have not changed, maintaining a stable development momentum. In the general environment of national fixed assets investment growth and economic stability, with the help of“ Dual carbon; The goal is to achieve green and low-carbon development, promote the coordinated development of intelligent construction and building industrialization, and provide a more favorable environment and stage for the promotion and application of steel structure buildings
From the perspective of the construction steel structure industry, facing the impact of the three-year epidemic and economic pressure, the entire industry has conscientiously implemented the new development concept, and the construction steel structure industry has achieved gratifying results. The promotion and application of steel structure buildings have maintained a growth trend. From the perspective of output value, the total output value of the construction industry in China in 2022 will be 31.2 trillion yuan, of which the output value of steel structures will reach 991.85 billion yuan, accounting for 3.18% of the construction industry. The production of building steel structures is 92 million tons, with a production increase of 3.4%, accounting for 9.08% of the crude steel production
According to statistics, the construction area of steel structures under construction in 2022 was 481 million square meters, accounting for 3.07% of the total construction area that year. The output value, production volume, and proportion of under construction area of steel structures have steadily increased. Although the proportion in the construction industry is still not high, it has broad development prospects and significant room for improvement
From the characteristics of industry operation, the concentration of construction steel structure production capacity and technological agglomeration are evident. According to incomplete statistics, the top 100 steel structure enterprises in the industry completed a steel structure production of 36.624 million tons in 2022, accounting for 39.8% of the national construction steel structure production. The steel structure output value reached 231.42 billion yuan, accounting for 23.3% of the national construction steel structure output value
From the perspective of the development of large-scale enterprises, as of the end of 2022, there are 2842 first-class steel structure professional contracting qualification enterprises and more than 13800 second-class qualification enterprises in China. Among them, provinces with a large number of steel structure production enterprises include Jiangsu, Shandong, Fujian, Zhejiang, Henan, etc
From the perspective of industrial environment and policy background, with the increasing promotion of steel structure buildings by the state and local governments, relevant industrial policies have been introduced and implemented, driving the promotion and application of steel structures in the construction field. Steel structures are widely used in high-rise, large-span and spatial structures, industrial plant buildings, and large bridges, maintaining their advantages. In recent years, the proportion of their application in hospital and school buildings has increased significantly. The collaborative promotion characteristics of the industrial chain of steel structure buildings are obvious. Design, production, construction, and scientific research units work together to make up for shortcomings and strengthen buildings. The growth rate of enclosure wall panels that are matched with steel structures is fast, and the market for lightweight composite wall panels is promising. The production of floor support panels is increasing year by year, and the construction of steel structure residential buildings maintains a certain growth momentum
From the perspective of technological innovation, steel structure enterprises actively promote the construction of a scientific and technological innovation system, continuously increasing research and development investment. Through data from 41 high-tech enterprises in the industry, it was found that research and development investment accounted for about 3.2% of total operating income in 2022. The per capita scientific research investment of the declared enterprise is about 353000 yuan. The amount and proportion of enterprise research investment have been increasing year by year, and attaching importance to scientific research development has become a new trend
Currently, China has entered a stage of high-quality development, and the industrial structure will undergo deep adjustments, with economic growth shifting from high-speed development to high-quality development. The steel structure industry in our country should take industrialization, informatization, and intelligence as common goals. Give full play to the leading role of technological innovation support, vigorously promote the deep integration of new generation information technology, advanced manufacturing technology, energy-saving and environmental protection technology, high-performance material technology and the construction industry through pilot demonstration and application of innovative achievements, use information technology and intelligent construction technology integration to maximize the integration efficiency and intelligence level of prefabricated buildings, promote the transformation and upgrading of industry industrialization, digitization, intelligence and green development, continuously shape new driving forces and advantages for development, and play a leading and demonstrative role in the field of green and low-carbon development of urban and rural construction
