Xirong Steel Structure Company announces industry trends

Xirong steel structure steel structure company feels that the steel structure industry in the construction industry in recent years a building material is constantly developing, but the steel structure industry in the development also has many problems, now with the Xirong steel structure steel structure company to understand the specific development trend of the steel structure industry.

The "Eleventh Five-Year Plan" building steel structure development goals are clear, vigorously promote the development of building steel structure, must further improve the level of application technology. High-rise and supertall buildings give priority to reasonable steel structure or steel-concrete structural system. Long-span buildings actively adopt spatial grid structure, three-dimensional truss structure, cable membrane structure, and structural system with prestress. Low-rise buildings vigorously promote the use of affordable steel structure systems. It is necessary to summarize the pilot experience, combine market demand, actively develop the steel structure residential building system, and gradually realize industrialization. In 2010, the amount of steel used in building steel structure strives to reach 6% of the total national steel output, and at the same time, the comprehensive technical level of building steel structure is close to or reaches the international advanced level.

Actively expand the variety of steel used in building steel structures to improve product performance. Research and development of high-performance building special steel series products, including high-quality welded structural steel, high-strength high-quality thick plate, thermoformed pipe, high-quality weldable cast steel, etc. Expand the variety and specifications of cold-formed and hot-rolled H-beams, including large-section cold-formed pipes, large-section H-beams and light H-beams. Reasonably promote the use of weathering steel, refractory steel, Z-oriented steel and flux cored electrodes. In 2010, the goal of localization of steel for building steel structures was basically realized.

According to the proportion of national economic growth, the output of steel structure increases at an annual rate of 10%, reaching 17.38 million tons in 2006 and 20 million tons in 2007. According to the current economic development rate, the output of steel structure in 2010 will reach 26 million tons, and there will be a breakthrough. The following statistics reflect the considerable development momentum of steel structure: in 2006, the steel structure in Xiaoshan area of Zhejiang reached 1.7 million tons, the amount of radio and television microwave communication towers and masts used was more than 500,000 tons, the transmission and transformation tower was 1.5 million tons, the railway bridge reached 500,000 tons, and the amount of steel used for highway bridges and installations increased rapidly.

In the coming period, the amount of steel structure in several fields in China will increase. Mainly: the construction of thermal power plants will be accelerated, and the amount of steel used in the main plant and boiler steel frame will increase (including steel for nuclear power plant buildings, steel for wind power generation, etc.); Bridges in traffic engineering will increase, railway bridges are made of steel structure, in recent years highway bridges using steel structure has also become a development trend, Beijing-Shanghai high-speed, cross-sea, cross-river bridges using steel bridges, highway guardrails, toll stations, traffic signs steel structure consumption is also a lot. and the construction and expansion of airports and railway stations; The amount of steel structure used in municipal construction will increase, and steel structures are increasingly used in subway and light rail projects, urban overpasses, viaducts, environmental protection projects, urban public facilities and temporary houses. Especially in Beijing, Shanghai, Tianjin, Chongqing and major provincial capitals, economically developed medium-sized cities, steel consumption will increase significantly. For example, Beijing uses more than 20,000 tons of steel for viaducts every year. The supporting facilities of the Beijing Olympic Games, Shanghai World Expo, Guangzhou Asian Games, and Shenzhen World Youth Games will adopt a large number of steel structure buildings; Steel structure residences will increase. The state advocates the construction of energy-saving and land-saving housing, and the design specifications and supporting technologies and materials of steel structure houses are basically available. At present, there are only a few million square meters of steel structure housing in China, but 40~50% in developed countries. For example, 5% of China's 600 million square meters of urban residential construction completed every year adopts steel structure, and the amount of steel used will reach 1.5 million tons per year according to the average of 50 kg of steel per square meter of multi-storey and high-rise buildings. The above figures do not include the steel structure used in rural buildings; Due to the lower price of steel in China than the international price, low labor cost, excellent steel structure production quality, and strong competitiveness in the international engineering market, foreign enterprises have increased their purchase of steel structures in China in recent years, and many steel structure factories have undertaken overseas orders.

However, at present, there are still many problems in China's steel structure industry, mainly including: First, the understanding that the steel structure industry is in line with energy conservation and environmental protection and sustainable development needs to be improved. In recent years, the governments and research institutions of Japan, Canada, and the United Kingdom have published many articles specifically on the advantages and measures of developing steel structure houses, which can be used for reference. Second, the design concept cannot meet the needs of the market. For example, most of the buildings with special requirements are won by foreign architects, and they do have unique features in planning, environment, architecture and function. However, the connection nodes are too complex, consume too much steel, create more difficulties with production and installation, and increase engineering costs. Third, steel structure enterprises in some areas are blindly on the horse and rush up, resulting in overcapacity and wasting a lot of resources. Fourth, the market operation is not standardized, bidding enterprises compete to reduce prices and steel prices rise, resulting in losses for processing and installation enterprises. Fifth, the funds for steel structure scientific research and development are insufficient, and the revision cycle of standards and specifications is too long; Missing items and lagging standards and application specifications and procedures; Steel standards are not connected with engineering design and construction specifications and regulations. Sixth, steel structure processing plants and construction and installation enterprise equipment, computer management, labor productivity need to be further improved. Seventh, there is a shortage of professional and technical personnel and skilled workers in steel structures, especially in small and medium-sized enterprises, and the technical quality and management of enterprises are not suitable for the needs of production. Eighth, the role and function of industry associations are far from in place. In particular, there is still a lot of work to be done in regulating and guiding market order, serving enterprises, opening up the steel structure market, the preparation and revision of standards and specifications and the training of professional talents.
