1. steel structure industry overview

Steel structure refers to the form of building structure with steel as the main bearing material, which has the advantages of light weight, strong shock resistance, short construction period, recyclable and so on. Steel structures are widely used in industrial plants, public buildings, bridge engineering, rail transit and other fields. According to different uses and forms, steel structures can be divided into heavy steel structures, light steel structures and fabricated steel structures.

In recent years, under the general policy of "double carbon", "emission reduction" and "sustainable development" have become the core of domestic industrial development, and the structural reform of the construction industry has become the general trend. Compared with traditional concrete buildings, steel structure buildings have obvious advantages in energy saving and emission reduction. According to data from the Shangpu Consulting Group, compared with concrete buildings, steel buildings can save energy during the life cycle.30%-50%Reduce CO2 emissions40%-60%Reduction of solid waste70%-80%. Therefore, national policies and market demand have given great attention and support to steel structure buildings.

In addition, with the improvement of people's quality of life, public buildings, commercial buildings, stadiums and other fields also have a greater demand for steel structures.

（3) technological innovation.2022The steel structure industry has achieved a series of results in technological innovation. For example, China's first super high-rise steel structure building——Shanghai Tower officially completed and put into use; China's first sea-crossing bridge——The Hong Kong-Zhuhai-Macao Bridge has successfully completed the entire line; China's first independent design, independent construction, and independent operation of the polar scientific research station——Kunlun Station officially opened; China's first world's largest single airport terminal——Beijing Daxing International Airport was officially put into operation. These projects fully demonstrate the technical level and innovation ability of China's steel structure industry in design, manufacturing and construction.

To sum up,2022The steel structure industry is developing well in the year, with production reaching10430Ten thousand tons, year-on-year growth9.5%. The largest amount of plate, reaching the total output60%Left and right.2022The steel structure industry's demand for sheet products exceeds6300Ten thousand tons, become the sunrise industry to drive the demand for plate products.

3.2023Development Trend Forecast of Steel Structure Industry in

Outlook2023In 2010, the steel structure industry will continue to maintain a high growth rate, mainly for the following reasons:

（1) policy continues.2023The year is the first year to fully implement the spirit of the 20th National Congress of the Communist Party of China. Global economic growth is facing slowing pressure. China's economy will gradually return to the normal growth track in the steady growth policy of expanding domestic demand. The steel industry will continue to adhere to green and low-carbon development,“Capacity reduction replacement”、“Ultra-low emission retrofit”、“Extreme Energy Efficiency Engineering”Advance will still restrict the release of steel production, steel demand decline has a certain easing, steel exports fell slightly; raw material prices further downward on the market support continues to weaken. In this context, steel structure building as an energy-saving emission reduction, efficient and environmentally friendly building form, will continue to be supported by national policies and market demand.

（2) market expansion.2023The growth rate of domestic infrastructure investment is expected to be6%, forming more physical workload, pulling the demand for steel structures to increase. Especially in rail transit, bridge engineering, airport facilities and other fields, the demand for steel structure is large. According to data from the Champ Consulting Group,2023National rail transit investment is expected to reach1.2Trillion yuan, year-on-year growth9.1%The national investment in new bridge projects is expected to reach1.4Trillion yuan, year-on-year growth7.7%; investment in airport facilities nationwide is expected to reach0.9Trillion yuan, year-on-year growth12.5%. In addition, with the improvement of people's quality of life, public buildings, commercial buildings, stadiums and other fields also have a greater demand for steel structures.

（3) technological progress.2023The steel structure industry will make more breakthroughs in technological progress.

Challenges and Suggestions for Steel Structure Industry in 4.

Although the steel structure industry has broad prospects for development, it also faces some challenges and problems that need to be paid attention to and solved. Mainly in the following aspects:

（11) The steel structure standard system is not perfect. At present, the standard system of China's steel structure industry is not perfect, the lack of some key technical specifications and quality standards, resulting in steel structure design, manufacturing, construction, testing and other links there is a certain degree of randomness and non-standardization, affecting the quality and safety of steel structure buildings. It is suggested to speed up the formulation and improvement of the standard system of steel structure industry and improve the technical level and quality level of steel structure buildings.

（21) Lack of steel structure talents. At present, the talent team of China's steel structure industry is not strong enough, lack of some high-level professionals and technical personnel, resulting in the lack of innovation and competitiveness of the steel structure industry, it is difficult to adapt to the changes and development of market demand. It is suggested to strengthen the training and introduction of talents in the steel structure industry, and improve the talent level and innovation ability of the steel structure industry.

（3) The steel structure market is highly competitive. At present, the market competition in China's steel structure industry is very fierce, and there are some vicious competition and low-price competition, which leads to the compression of the profit space of steel structure enterprises and affects the healthy development of the steel structure industry. It is recommended to strengthen the supervision and regulation of the steel structure industry, crack down on violations of laws and regulations, and maintain the fairness and order of the steel structure market.

（44) The popularization and application of steel structure is not wide enough. At present, China's steel structure buildings have not been fully promoted and applied in some fields, and there are some misunderstandings and obstacles to use, resulting in the market potential of steel structure buildings has not been fully released. It is suggested to strengthen the publicity and promotion of steel structure buildings, and improve the awareness and acceptance of steel structure buildings from all walks of life.

Anyway,2023The steel structure industry will continue to maintain a high growth rate, and the demand for steel products such as plates and profiles will increase. But at the same time, we should also pay attention to solve some challenges and problems faced by the steel structure industry, and promote the healthy development of the steel structure industry.
